👨‍💻 Junior Software Engineer

📍 Hybrid - Southampton (1 day fortnightly) | 💰 £40-60k + Equity | 🧱 Deep-Tech Startup | 🌍 £60B Market Opportunity

We're hiring on behalf of a well-funded deep-tech startup that's going after a £60B problem - making enterprise databases interchangeable. Backed by £1.2M in pre-seed and scaling toward a £7M raise, they're already live with major customers and building out their UK engineering team as they hit their next growth phase.

If you're a curious, ambitious junior engineer who's comfortable across multiple languages and ready to take on hard problems - this is your shot to learn fast, contribute early, and grow with the business.

The Mission:

They're building a platform that lets enterprise applications move between SQL databases (PostgreSQL, MySQL, Oracle, etc.) without needing rewrites - solving deep interoperability and performance challenges that most teams wouldn't even dare touch.

What You'll Be Doing:

• Contributing to the development of a world-first database virtualisation platform
• Solving complex problems around speed, scale, and system design
• Working with modern tools and multiple languages (and learning new ones as you go)
• Writing clean, testable code and taking part in peer reviews
• Helping shape the early tech and product roadmap

What You'll Need:

• Proficiency in 3+ programming languages (e.g., C++, TypeScript, Python, Java, Rust)
• Solid understanding of data structures, algorithms, and system fundamentals
• Experience working with SQL databases (e.g., PostgreSQL, MySQL, Oracle)
• Willingness to tackle new tools and unfamiliar problems
• Strong communication and collaborative mindset

Nice to Have:

• Any experience with Docker, Kubernetes, or cloud platforms (Azure, AWS, GCP)
• Knowledge of database internals or data migration concepts
• Familiarity with CI/CD (e.g., GitHub Actions)

Tech You'll Touch:

Linux, C++, TypeScript, PostgreSQL, LLVM

Docker, Kubernetes, GitHub, Azure

Why You Should Join:

✅ Solve real-world, enterprise-scale problems from day one

✅ Work with senior engineers and learn in an environment that challenges you

✅ Join just before a major growth phase - real ownership, real upside

✅ Equity on offer - because your contributions will matter
