Senior Software Developer

Senior Software Developer Surrey Hybrid £65,000 - £75,000

Are you an experienced systems-level engineer craving impact We're seeking a Senior Software Developer versed in Rust, or an equivalent systems language, who thrives in high-availability, mission-critical environments.

Our client is a fast-growing technology provider delivering next-generation communications solutions to a global customer base. With ambitious growth plans and investment backing, this is a chance to join a forward-thinking engineering team where you'll make a real impact.

You'll play a key role in architecting, building, and optimising telecommunications systems in Rust, contributing to secure, high-performance, and scalable solutions used worldwide.

You'll collaborate closely across DevOps, API (Java), front-end, and database teams, and be empowered to drive meaningful architectural and reliability improvements.

What You'll Do

• Build and scale: Develop production-grade features in Rust (or onboard quickly if transitioning from C/C++).
• High-availability focus: Help ensure uptime and performance in a real-time, mission-critical telecom platform.
• Collaborate broadly: Work across disciplines to improve stability, maintainability, and scalability.
• Mentor and learn: Benefit from peer mentoring, and share your knowledge in turn. Training and external learning support are available.
• Be proactive: Opportunities abound to own improvements, suggest architectural refinements, and shape technology direction.

What We're Looking For

Three key areas of experience, strong candidates may excel in any one or two:

• Rust programming or equivalent systems-level expertise
  • Proven experience in Rust development is ideal, but strong developers in C, C++, or similar systems languages are very welcome.
• Telecommunications or comparable high-availability background
  • Ideal: SIP, VoIP, 5G, or telecom protocol knowledge.
  • Alternatively: experience in sectors like fintech, trading, or infrastructure where reliability and performance are paramount.
• Low-level systems and distributed systems know-how
  • Familiar with designing or optimizing scalable, performance-critical platforms under pressure.

Experts in one area who can learn quickly in another are highly valued and will be supported through mentorship and training.

Qualifications

• Robust software engineering foundation (systems-level preferred).
• Some experience with Rust, or strong proficiency in another low-level language.
• Domain experience in telecoms, fintech, or similarly demanding architectures.
• Familiarity with distributed systems design, performance tuning, and system reliability.
• Proactive mindset and excellent cross-functional communication.

What's in it for you

• Competitive salary & benefits
• Health cash plans, enhanced leave for new parents, and ongoing training opportunities
• Supportive "Team First" culture with team events and industry networking
• A workplace committed to diversity, inclusion, and professional growth
