About the role
Staff Backend Engineers shape technical direction across teams while remaining close to the systems and code. You will take on problems whose consequences extend beyond one service or delivery cycle.
This is not a people-management role. Its leverage comes from technical judgement, credible execution and the ability to help other engineers make better decisions.
What you’ll do
- Own high-consequence backend problems that span services, teams or product domains.
- Establish clear system boundaries and architectural direction without creating unnecessary central control.
- Lead technical decisions by making constraints, alternatives, risks and trade-offs explicit.
- Improve performance, resilience, data integrity, operability and failure handling across production systems.
- Resolve recurring structural problems rather than treating symptoms team by team.
- Remain hands-on where implementation, diagnosis or prototyping is the fastest way to create clarity.
- Mentor senior engineers, raise review quality and make strong engineering judgement easier to reproduce across teams.
- Partner with engineering and product leaders on sequencing, risk and long-term technical investment.
What you need to have
- Evidence of technical impact across multiple teams or a substantial product domain.
- Deep ownership of distributed backend systems operating at meaningful scale.
- Strong judgement in service boundaries, asynchronous communication, data ownership, consistency and failure modes.
- Deep knowledge of relational databases, transactions, concurrency and high-performance design.
- A track record of improving reliability, scalability, observability or developer effectiveness through durable mechanisms.
- The ability to influence technical direction through evidence, clarity and trusted execution rather than title.
- Clear communication that helps teams act on complex technical decisions.
- Strong engineering fundamentals and the judgement to choose when to standardise, simplify or leave a system alone.
Staff scope is assessed through ownership, judgement and sustained organisational impact—not years of experience or familiarity with every technology listed.

Trading 212
View Company ProfileTrading 212 (operating under trading212.com) is the premier, enterprise-grade fintech brokerage pioneer, democratized asset management innovator, and cross-border financial technology powerhouse engineered to operate as the definitive, high-velocity commission-free stock trading, fractional share investing, and contract-for-difference (CFD) execution layer for retail investors across the United Kingdom, Europe, and global financial markets. The company completely eliminates the severe systemic friction of traditional retail investing—where individual capital builders lose immense wealth-building momentum to predatory per-trade commissions, hidden account custody fees, rigid minimum investment thresholds, and fragmented currency exchange markups—by deploying an advanced, zero-commission multi-asset delivery matrix. Moving far beyond traditional, legacy retail brokerages or basic high-fee financial apps, Trading 212 natively unifies a seamless mobile-first equity ecosystem, automated savings and investment portfolios (\"Pies & AutoInvest\"), tax-free Individual Savings Accounts (ISAs), self-invested personal pensions (SIPPs), and its unique multi-currency payment card featuring zero FX fees at true interbank rates into a single high-availability digital workspace. Managing over 5 million active funded accounts and safeguarding more than £25 billion in total client assets, the platform handles massive transactional concurrency and high-throughput order routing with production-hardened engineering precision. Under the hood, its sophisticated technical architecture coordinates real-time financial market data feeds, high-volume automated collateralized stock lending pipelines, and robust regulatory compliance guardrails strictly audited under elite supervisory bodies including the UK's Financial Conduct Authority (FCA), BaFin in Germany, and CySEC in Cyprus. What sets Trading 212 apart is its uncompromising dedication to replacing complex financial gatekeeping with absolute transactional transparency, cross-border accessibility, and wealth velocity; by bridging the gap between performance-intensive low-level systems engineering and an intuitive, retail-optimized interface, the group remains the definitive cornerstone of modern algorithmic retail investing and worldwide fintech infrastructure transformation.
