Who Are CSL Looking For?

We’re looking for an experienced IoT Senior Business Development Manager to drive new business growth for CSL across Europe. This is a pure new business hunting role: you’ll own the full sales cycle, from identifying and opening doors with target organisations, through shaping solutions and leading complex tender responses, to negotiating and closing large, multi-year IoT connectivity deals that create significant recurring revenue.

You’ll bring an established network across the IoT ecosystem – device manufacturers, solution providers, system integrators, and enterprise buyers and a proven track record of winning major deals through formal procurement processes, including tenders, RFPs, and RFIs. You’ll work alongside our technical, product, bid, and commercial teams to put forward compelling propositions built on CSL’s critical connectivity, multi-network resilience, and eSIM capability.

This is a high-impact role for a senior hunter who wants to make a visible difference in a fast-growing, private equity-backed business, with real influence over how we win in new markets and an incentive plan designed to reward large, high-value deals.

Duties & Responsibilities:

This role will encompass a range of responsibilities including but not limited to:

• Identify, target, and win new logos across Europe, focusing on large-scale IoT connectivity opportunities with significant recurring revenue potential
• Build and execute a territory and account plan aligned to CSL’s priority sectors and markets
• Open doors at senior level using your existing network, referrals, and targeted outbound activity
• Own a largely self-generated pipeline, maintaining the coverage needed to consistently deliver against targets
• Tenders & Complex Deal Leadership
• Lead CSL’s response to tenders, RFPs, RFIs, and other formal procurement processes, from qualification and bid/no-bid decisions through to final submission
• Coordinate technical, product, legal, finance, and bid colleagues to build compelling, compliant, and commercially sound proposals
• Shape deal structures, pricing, and commercial terms, including minimum commitments and rollout plans, working within CSL’s bid approval process
• Negotiate and close multi-year contracts with end customers and channel partners
• Solution Selling
• Understand customer use cases, device estates, and deployment plans to position the right mix of CSL connectivity, platform, and service capabilities
• Present complex IoT propositions clearly and confidently to technical, procurement, and executive audiences
• Build business cases that demonstrate value and clearly differentiate CSL from competitors
• Market & Partner Development
• Maintain a sharp view of the European IoT market, competitor activity, and procurement trends
• Develop relationships with OEMs, system integrators, solution providers, and industry bodies that open routes to large-scale opportunities
• Represent CSL at industry events, trade shows, and conferences to raise our profile and grow your network
• Pipeline, Forecasting & Handover
• Manage opportunities rigorously in the CRM (e.g. Salesforce), with accurate forecasting and deal reporting
• Work closely with Marketing and Sales Development to sharpen targeting and turn campaign activity into qualified opportunity
• Ensure a smooth handover to onboarding and account management so that won deals roll out on plan and convert into billed revenue

Key Skills & Qualifications Sought:

• Significant B2B new business sales experience (typically 8+ years), with a substantial part of that in IoT, M2M, or telecoms connectivity
• An established, active network across the European IoT ecosystem that you can bring to bear from day one
• A proven track record of winning major IoT deals, ideally multi-year contracts delivering six- and seven-figure annual recurring revenue
• Strong experience leading or contributing to tender, RFP, and RFI responses, across both public and private sector procurement
• Solid understanding of IoT connectivity, including cellular technologies (4G, 5G, LTE-M, NB-IoT), multi-network and roaming solutions, eSIM, and connectivity management platforms
• Confident negotiator, comfortable structuring complex commercial deals and engaging at C-level
• Excellent communication and presentation skills, with the ability to make complex propositions simple
• A resilient, self-motivated hunter mentality – you thrive on opening new doors rather than managing existing accounts
• Comfortable working across a European territory, with regular travel to customers, partners, and industry events
• Fluent English essential; additional European languages a strong plus
• Experience in one or more of CSL’s target sectors (Building & Security, Healthcare & Telecare, Infrastructure, Retail & Hospitality, Transport & Logistics) is desirable

What Success Looks Like:

• A strong, largely self-generated pipeline of large-scale new business opportunities across Europe
• Major new logos signed on multi-year contracts that create significant, sustainable recurring revenue
• High-quality tender and RFP submissions delivered on time, with a strong win rate on qualified bids

Who Are CSL Looking For?

We’re looking for a GTM Operations Manager to own the systems, data, and reporting that marketing and sales both depend on – and to be the person who can say, with numbers people trust, where revenue is coming from and what is holding it back.

This role starts as maternity cover for our Marketing Operations Specialist, so the marketing systems, data, and reporting engine has to keep running from day one. But it is deliberately broader than a like-for-like backfill. CSL has grown fast across multiple countries and integrated seven acquisitions – and the gap we need closing is the different definitions, different systems, and to build a full GTM operations function that supports go-to-market excellence, with an agentic first approach. You will be the first dedicated revenue operations hire, laying the foundations for a function that covers the full funnel.

Over time, the weight of the role shifts. As the marketing operations maternity cover ends, the focus moves towards sales operations – pipeline discipline, forecasting, territory and quota support, and commercial reporting – as part of an evolving revenue operations function. We are being open about that from the start: this is a role that changes shape, and we want someone who finds that interesting rather than unsettling.

You’ll be technical enough to build and troubleshoot, be commercial enough to know which numbers matter, and be curious to quickly adapt to new and evolving technologies. You will also be central to how CSL uses AI across the revenue engine – automating the repetitive, and building the infrastructure that lets the wider team get business intelligence to know which levers to pull to grow revenue.

Duties & Responsibilities:

This role will encompass a range of responsibilities including but not limited to:

Revenue Reporting, Forecasting & Insight

• Own end-to-end funnel reporting – from enquiry through to closed won – so marketing, sales, and leadership work from one set of numbers.
• Build and maintain the forecasting process with Sales: pipeline coverage, conversion rates by stage, deal velocity, and forecast accuracy.
• Own attribution and source reporting, and make sure regional and Group reporting reconcile.
• Turn data into insight and recommendations for the CMO and commercial leadership – what to do differently, not just what happened.
• Report on the commercial return of marketing and sales investment, including cost per opportunity and pipeline contribution by channel and region.

Sales Operations & Pipeline

• Own pipeline hygiene and CRM discipline: stage definitions, exit criteria, close dates, and data completeness.
• Own lead lifecycle and routing end to end – definitions, scoring, assignment rules, SLAs, and the handover from marketing into sales – and hold both sides to it.
• Support sales process improvement, including building a revtech roadmap quoting, and improving the operational detail that slows deals down.
• Provide the operational inputs behind territory design, target setting, and quota and commission calculation.
• Partner with Sales leadership on shared process, definitions, and reporting across the funnel.

Marketing Operations (Maternity Cover Period)

• Own the marketing technology stack – administration, integration, adoption, vendor relationships, licences, and cost.
• Own marketing automation build and governance: templates, programmes, scoring, nurture logic, and preference management.
• Support the marketing team with campaign setup, tracking, and quality assurance so activity is measurable from the start.
• Manage deliverability, consent, and compliance across markets, including GDPR obligations.
• Provide the regional marketers and the Senior Marketing Manager with the reporting they need against their pipeline and coverage targets.

Systems, Data & Governance

• Own data quality across CRM and marketing platforms – deduplication, enrichment, segmentation structure, and account and contact hygiene across regions.
• Define and document the data model, naming conventions, and taxonomy that marketing and sales both work to.
• Manage integrations between systems so data flows without manual intervention.
• Bring data from acquisitions and third-party sources into the core platforms cleanly.
• Set and maintain governance so the numbers mean the same thing in every report, in every country.

AI, Automation & the Revenue Brain

• Identify and automate the repetitive operational work across marketing and sales, using AI and workflow tooling where it genuinely saves time.
• Build and maintain the technical infrastructure behind CSL’s central ‘brain’ – the shared, structured store of positioning, messaging, proof points, customer language, and performance data – extending it to cover sales conversations and commercial outcomes.
• Build agents and workflows that let marketing and sales query performance data and reusable content without waiting on a report.
• Use AI-assisted analysis for reporting, anomaly spotting, and post-campaign and post-quarter review, with proper validation before anything is acted on.
• Set practical standards for safe, compliant AI and data use across the commercial team.

Key Skills & Qualifications Sought:

• Solid revenue operations, sales operations, or marketing operations experience in a B2B environment – with genuine exposure to both sides of the funnel.
• Hands-on experience administering CRM and marketing automation platforms (e.g. Salesforce, Pardot, HubSpot).
• Strong command of pipeline and funnel metrics, and how commercial performance is actually built from the underlying data.
• Experience supporting a sales forecasting process, and the judgement to know when a forecast is being optimistic.
• Strong data skills – comfortable with data structures, segmentation, deduplication, and reconciliation across systems.
• Experience building dashboards and reporting in BI or AI tools, and explaining the results to non-technical stakeholders.
• Working knowledge of GDPR and data compliance across multiple countries.
• Confident building AI-assisted and automated workflows, with sound judgement on data quality, security, and validation.
• Comfortable working with integrations, APIs, or scripting is a strong advantage.
• Credible with sales people – able to hold the line on process and data discipline without losing the room.
• Methodical, precise, and able to bring order to systems and data inherited from multiple sources.
• Comfortable with a role that changes shape, and interested in building a function rather than inheriting one.

How the Role will Evolve:

Months 1–12 – Cover and Foundations

• Full ownership of marketing operations during the maternity cover period: martech stack, marketing automation, campaign operations, data quality, and marketing reporting.
• Establish shared funnel definitions, a single agreed set of revenue metrics, and reporting that marketing and sales both recognise.
• Diagnose and fix the highest-value gaps in sales process and pipeline data – lead handover, opportunity hygiene, and forecast inputs.
• Produce the first integrated revenue reporting pack for the CMO and commercial leadership.

Month 12 Onwards – Integrated GTM/Agentic Operations

• Transition marketing operations back cleanly, with documented process, governance, and reporting.
• Shift the centre of gravity to sales operations: forecasting, pipeline management, territory and quota support, commission inputs, and sales performance reporting.
• Scale the function.

The above should not be viewed as an exhaustive list of skills and/or qualifications but rather CSLs view on the ideal candidate.
