? Backend Engineer - Scale Systems with Real Impact ?
Tired of tinkering at the edges? Want to actually shape the backbone of a platform that’s transforming how the world’s biggest enterprises run their tech? This is one of those rare roles where you get in early, build the foundations, and watch your work scale across global businesses.
We’re working with a high-growth London startup on a mission to reinvent enterprise software. Their AI-driven platform is already saving household-name customers millions in IT costs, shaving months off ERP project timelines, and making sense of the mess that legacy systems leave behind. SAP is just the beginning - they’re building a whole new category of Enterprise System Intelligence.
The RoleAs one of the first Backend Engineers focused on platform and infrastructure, you’ll:
Build core systems capable of handling tens of millions of lines of code and large-scale LLM workloads.
Own big pieces of the architecture - from job orchestration to APIs, infra, and developer tooling.
Make product teams fly by building reliable, well-designed infrastructure that scales without slowing anyone down.
Tame complex LLM infrastructure (real-time usage, flaky providers, token routing - the lot).
Raise the quality bar across the board: observability, auth, reliability, and more.
This isn’t a role for passengers. It’s for engineers who love ambiguity, thrive under pressure, and see infrastructure as a multiplier.
What We’re Looking For
3+ years backend engineering experience (ideally with some distributed systems / infra focus).
Exposure to high-velocity startups and the shift from scrappy MVPs to rock-solid systems.
Strong system design skills - taking problems end-to-end, not just handing off parts.
Bonus if you’ve wrangled LLM infrastructure at scale.
Pragmatic, resourceful, and happy to operate autonomously in lean teams.
Excited to work onsite in Soho, London with a team that’s building something exceptional.
Tech Snapshot (don’t worry if you don’t know it all): Kotlin, TypeScript, Terraform, Azure/AWS/GCP, Temporal, Postgres, graph databases, OpenTelemetry, Grafana, containerised dev environments, CI/CD pipelines.
Perks & Culture Competitive salary + EMI share options ? Breakfast and dinner on tap, plus snacks that raise the bar ? Regular socials + full-team offsites twice a year Private health cover (dental + optical included) Monthly wellbeing budget Unlimited holiday (take what you need, no counting) High-trust, high-energy culture - serious about impact, never too serious about ourselves
If you’ve been itching to do meaningful engineering in a startup that’s scaling fast, this is your shot.
