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 would 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 they are looking for
* 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.
