Software Engineer

Software Engineer
UK Based | Remote Friendly
£35,000 to £70,000 depending on level

A high-growth engineering consultancy is expanding its software team as it scales significantly over the next 12 to 18 months.

This is not a maintenance role. This is an opportunity to build technically complex systems from scratch, often at the intersection of software and hardware, across cutting-edge sectors including biotech, quantum computing, heavy industry and government-backed R&D.

Due to strong inbound demand, the business is hiring across multiple levels.

The Role

You will work in small, multidisciplinary teams delivering bespoke engineering solutions. Projects are technically challenging and require strong engineering fundamentals, production-quality code and real ownership.

This environment suits engineers who enjoy solving complex problems rather than simply implementing tickets.

Opportunities are available at:

  • Graduate Software Engineer
  • Senior Software Engineer
  • Senior Software Engineer (Advanced / Principal Level)

There is flexibility on title for exceptional candidates.

Technology Environment

Core stack includes:

  • C++
  • Python
  • JavaScript or TypeScript

Frontend and backend development

Desirable experience:

  • Firmware or microcontrollers
  • Hardware integration
  • LLM tools or AI-assisted development
  • UX or interface thinking

Strong engineering principles matter more than matching every technology exactly.

What They Are Looking For

  • Graduate level:
  • Strong fundamentals
  • Demonstrable coding ability
  • Curiosity and fast learning capability

Senior level:

  • 3+ years commercial experience
  • Experience delivering production systems
  • Strong ownership and accountability

Advanced Senior level:

  • Deep technical capability
  • Architectural judgement
  • Comfort making engineering decisions
  • Potential mentoring influence

Working Model

  • UK based only
  • Remote friendly
  • Occasional office presence required
  • Flexible hours
  • Generous holiday allowance
  • Additional office-day benefits

Why Join

High-growth environment with strong financial backing

Complex, meaningful engineering challenges

Direct access to leadership

Opportunity to shape a scaling team

Strong project demand and pipeline

This is an engineering-led environment that values quality, intellectual honesty and high standards.

If you are looking to build real systems with impact rather than maintain legacy code, this is a rare opportunity to join at an exciting stage of growth.
