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.

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)
