Polyglot Software Engineer

📍 Hybrid - Southampton (1 day fortnightly) | 💰 £60-80k + Equity | 🧱 Deep-Tech Startup | 🌍 £60B Market Opportunity

We're working with an early-stage deep-tech startup that's gunning for a slice of the £60B SQL database market - and doing so with serious technical firepower.

Fresh off a £1.2M pre-seed and mid-way through a further £7M raise, they already have live enterprise customers and a product solving high-stakes, real-world problems. This is a true ground-floor opportunity - you'll be working on core product and platform decisions, right as they scale their UK engineering team.

The Mission:
They're building a platform that makes databases interchangeable - allowing enterprise applications to move seamlessly between different SQL databases (PostgreSQL, MySQL, Oracle, etc.) without rewriting core logic. Think: zero-downtime migrations, deep system integration, and high-performance virtualisation.

What You'll Be Doing:

Building features for a next-gen database virtualisation platform
Tackling performance, scalability, and system interoperability challenges
Writing clean, well-tested code in multiple languages
Working cross-functionally with product, DevOps, and architecture teams
Helping shape the technical roadmap and scaling engineering processesWhat You'll Need:

Proficiency in 3+ languages (e.g., C++, TypeScript, Python, Java, Rust)
Strong fundamentals in algorithms, systems design, and data structures
Experience with SQL databases (e.g., PostgreSQL, MySQL, Oracle)
Ability to pick up new tech fast and solve complex problems independently
Comfortable operating in a fast-paced, early-stage environmentNice to Have:

Deep understanding of database internals or data migration
Experience with Docker, Kubernetes, and cloud platforms (Azure, AWS, GCP)
Familiarity with CI/CD and DevOps tooling (e.g., GitHub Actions)The Stack:
Linux, C++, TypeScript, PostgreSQL, LLVM
Docker, Kubernetes, GitHub, Azure

Why It's Exciting:
✅ Join at the inflection point - live customers, big funding round, rapid growth ahead
✅ Take ownership of core engineering challenges that actually matter
✅ Be part of building something technically ambitious and commercially disruptive
✅ Equity on offer - strong long-term upside

This one's perfect for engineers who love tough problems, clean design, and working across languages and platforms. If that's you, drop me a message and let's have a chat.
