Careers

Who Are CSL Looking For?

We are looking for an experienced Proposal Manager with strong bid writing and coordination skills, and the confidence to handle technical material. This hybrid role combines hands-on writing with bid management, ensuring we deliver high-quality, competitive responses to RFPs, RFIs, and tenders.

You will work across teams including Sales, Business Development, Product, Engineering, Commercial, and Finance to produce proposals that bring our SIM technologies to life. Success in this role means writing responses that are accurate, persuasive, and enjoyable to read: capturing technical detail while keeping a clear, human voice.

In some cases, you will also support operator bid teams when they incorporate rSIM into their proposals, providing input, coordination, and technical material to ensure rSIM is positioned well. Each bid is unique. Success in this role means going beyond reusing content: it is about tuning into the customer’s language and priorities and shaping our response so it directly reflects their needs and evaluation criteria.

Duties & Responsibilities:

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

During Active Bids (RFPs, RFIs, Tenders):

• Lead the end-to-end bid process, from opportunity qualification through to submission
• Write and edit clear, persuasive responses that capture technical inputs in a way customers
  understand
• Coordinate contributions from Sales, Product, Engineering, Commercial, and Finance teams,
  ensuring deadlines and compliance requirements are met
• Support operator bid teams when they incorporate rSIM into their proposals, providing input,
  coordination, and technical material to ensure rSIM is positioned well
• Develop diagrams, solution descriptions, and value propositions that differentiate rSIM from
  competitors
• Analyse RFPs and RFIs to identify gaps, ambiguities, and opportunities, and frame strategic
  clarification questions that give us an edge
• Manage review cycles and sign-offs, ensuring proposals are accurate, consistent, and tailored
• Support bid presentations and clarifications where written responses extend into oral defence
  stages

During Non-Bid Periods:

• Build and maintain a knowledge base of case studies, technical explanations, and compliance
  documents, while ensuring all responses are tailored to each opportunity
• Work with Sales and Business Development to maintain a pipeline tracker of upcoming
  opportunities and ensure pre-qualification requirements are in place
• Collaborate with Product and Engineering to capture technical detail and turn it into customer-
  ready material
• Research competitor positioning, market developments, and regulatory changes to strengthen
  future responses
• Support Marketing in producing thought leadership, white papers, and case studies that can
  also be used in bids
• Support the sales team in using Proposify for smaller, routine offers, ensuring responses are
  clear, consistent, and aligned with rSIM messaging

We are looking for someone who is:

• A natural writer who takes pride in producing well-structured, engaging, human responses
  rather than relying on generic AI content
• Skilled at adapting writing style to reflect the customer’s language, priorities, and evaluation
  criteria
• A strategic thinker who can read between the lines of RFPs, asking smart questions that
  uncover customer priorities and create opportunities f or differentiation
• Detail-oriented, with a right-first-time mindset
• Resilient under pressure, with the ability to manage multiple deadline
• Flexible and adaptable, willing to work outside of standard hours when bids require fast
  turnaround (f or example, when partners such as T-Mobile provide short notice)
• Curious, proactive, and able to identify ways to continuously improve bid quality
• Comfortable switching between complex bids and smaller proposals in Proposify, keeping
  quality of writing high in both
• Comfortable in a hybrid role that blends technical writing, project coordination, and stakeholder
  management

Key Skills & Qualifications Sought:

• Proven experience as a Bid Writer, Proposal Manager, or Bid Manager within telecoms, IoT, or technology sectors

• Strong writing skills: able to translate complex technical inputs into clear, engaging responses

• Experience coordinating contributions from multiple stakeholders under tight deadlines

• Technical understanding of mobile connectivity, IoT, or telecoms (SIMs, eSIM, APNs, private networks)

• Excellent project management and organisational skills

• Commercial awareness and the ability to position solutions competitively

• Proficient in MS Office (Word, PowerPoint, Excel); experience with collaboration tools such as Teams, SharePoint, or Confluence is beneficial

• APMP qualification desirable but not essential
