Senior to Staff level Full Stack Engineer in London. Hybrid - 4 days in office. Permanent position with a salary of £110-150k (based on experience level) plus benefits, share options, and L&D budget.
We’re working with a company building genuinely difficult systems at the intersection of AI, infrastructure, and real-world operational complexity. The platform focuses on helping large organizations better understand, simulate, and optimize highly complex operational environments using large-scale data, AI models, and real-time system interactions.
A huge part of the challenge lies in turning messy, constantly evolving real-world inputs into reliable, scalable, and commercially useful systems that customers can trust. The team is intentionally language agnostic; they care far less about whether you write Go, Python, Rust, or Java, and far more about how you think.
The environment would likely suit engineers coming from high-scale startups, platform teams, AI infrastructure environments, developer tooling companies, or complex backend/product engineering organizations.
If you enjoy solving genuinely difficult engineering problems but can also connect those decisions back to product and business impact, this will probably feel very different from most opportunities currently on the market.
Are you someone who:
- naturally thinks in systems
- enjoys unpacking complexity
- can clearly explain trade-offs and architectural decisions
- understands the “why” behind technical choices
- takes ownership beyond just implementation
- can move between infrastructure, product, and business context comfortably
The strongest engineers here tend to:
- ask difficult questions early
- think deeply about scale, latency, resiliency, and operational behaviour
- care about communication as much as implementation
- understand customer and product impact
- bring structure and clarity to ambiguous problems
- enjoy collaborative technical discussion and healthy challenge
- platform and infrastructure design
