Location: London (Hybrid, 3 days onsite)

Salary: £130,000 - £170,000 + Benefits

Want your engineering work to contribute to breakthroughs in cancer research, drug discovery and next-generation healthcare?

I'm working with a mission-led technology company building advanced software, AI and automation platforms that help accelerate scientific discovery. This is a genuine tech-for-good opportunity where the systems you build can have a real-world impact beyond traditional software products.

We're hiring for multiple Staff Software Engineers across the platform, including opportunities focused on:

Core Systems

• Distributed systems
• Event-driven architecture
• Platform engineering
• Real-time execution systems
• AI and automation platforms

Product Engineering / User Experience

• TypeScript and React
• Product architecture
• Complex workflows and visualisation
• AI-enabled user experiences
• Building software used in highly technical environments

This role probably isn't for you if...

• You're looking for a pure people-management position and want to move away from hands-on engineering
• You prefer straightforward CRUD applications over complex technical and distributed systems challenges
• You want highly defined requirements rather than helping shape technical and product direction

What you'll be doing

• Leading technical direction for a key product area
• Designing and building highly scalable software platforms
• Influencing architecture and engineering standards
• Mentoring senior engineers whilst remaining hands-on
• Working across Product, Platform, AI and Design teams
• Helping define the future direction of both the technology and engineering culture

Tech Environment

• Go, Python
• TypeScript, React
• GraphQL
• Kubernetes
• gRPC
• Event-Driven Architecture
• NATS
• OpenTelemetry
• AI / Agentic Systems

We're looking for engineers who

• Have experience building complex software products at scale
• Possess strong architecture and system design skills
• Lead through technical influence rather than pure people management
• Enjoy solving difficult engineering challenges

Why join?

• Work on technology helping accelerate scientific and healthcare breakthroughs
• Tackle genuinely difficult engineering challenges involving AI, automation and distributed systems
• Join a high-calibre engineering culture with significant autonomy
• Shape the architecture of a rapidly evolving platform
• Contribute towards technology supporting advances in areas such as cancer research, life sciences and healthcare innovation

If you're a Staff Engineer looking to solve meaningful problems, influence the direction of a world-class engineering organisation and build technology that can help drive scientific progress, I'd be keen to speak.
