Bit Zesty is looking for a talented Full Stack Software Engineer to join our growing team. Our core stack is Ruby on Rails, but we are looking for engineers who are excited to work across multiple technologies — including React, React Native, Python, and Elixir — and who embrace AI-assisted development as a core part of their workflow.
We build high-quality, scalable digital products for public sector organisations, charities, and fast-growing companies. You will work closely with our UX designers, project managers, and technical leadership to deliver excellent software that stands the test of time.
If you love shipping clean, reliable code and want to be part of a team that takes craft seriously, we would love to hear from you.
What You’ll Do
- Build and maintain high-quality Rails applications, as well as services in other languages/frameworks where required.
- Use AI tools (Cursor, Claude Code, Droid, etc.) to accelerate high-quality delivery — not replace engineering judgment.
- Contribute to architectural decisions, technical planning, and system design.
- Debug issues, optimise performance, and proactively propose improvements.
- Work with wireframes, mockups, and user stories to deliver well-designed systems.
- Participate in code reviews and foster a culture of engineering excellence.
- Own features end-to-end: from concept, to development, to deployment and monitoring.
- Work across multiple live client projects and handle context-switching confidently.
What We’re Looking For
- Strong Ruby on Rails experience, ideally across multiple production applications.
- Comfortable working in existing codebases and shipping within real-world constraints.
- Experience with SQL (PostgreSQL/MySQL) and some exposure to NoSQL stores.
- Willingness and enthusiasm to work with React, React Native, Python, or Elixir when needed.
- Sound understanding of version control, CI/CD, testing, and deployment pipelines.
We Expect You To
- Be excellent at prompting and using LLMs effectively.
- Know when to use Claude, Cursor, etc. — and when not to.
- Understand the difference between AI-assistance and outsourcing your thinking.
- Use AI to enhance speed, quality, reliability, and documentation.
- Have a strong engineering foundation for debugging, algorithms, and systems without relying on LLMs.
- We are not looking for vibe coders. We want thoughtful engineers who use AI as leverage, not a crutch.
Personal Qualities
- Comfortable collaborating synchronously with a team.
- Excellent attention to detail and communication skills.
- Ability to work across several projects at once.
- Curiosity, adaptability, and a desire to continually learn new tools and technologies.
- Agency experience is a bonus but not required.
- A degree in Computer Science, Software Engineering, or equivalent experience is welcome.
At Bit Zesty, we offer a range of perks and benefits to help you enjoy your time with us, such as:
- Fully remote working – work from anywhere in the UK
- Flexibility with working hours (full-time or part-time)
- High-spec equipment (MacBook Air, iPhone, Jabra headset, SAD lamp, etc.).
- 33 days holiday (25 days leave + UK bank holidays + your birthday off).
- Health & wellness contribution for gym or fitness apps
- Conference/training budget
- Private medical insurance
- Regular virtual team activities and a friendly, collaborative culture
- The chance to work on meaningful, impactful digital services used by thousands
