Job summary

You will design scalable, secure services used by multiple product teams, mentor engineers and collaborate with Security, Infrastructure and Architecture to deliver reliable solutions in a fully remote setup.

Qualifications

• Bachelor's degree in Computer Science or equivalent practical experience.
• 5+ years of professional backend engineering experience.
• Strong in Java, Go or another modern backend language.

• Own larger services end to end, including monitoring, alerting, on-call follow-up and support for the teams that use them.
• Design APIs that stay stable: contracts, versioning, backward compatibility and safe deprecation.
• Build and improve identity and access features, such as sign-in, sessions, tokens, permissions and account security.
• Make shared services resilient: rate limiting, graceful degradation, isolation between consumers and safe rollouts.
• Improve observability with useful metrics, logs and traces, and set service level objectives with the teams that depend on you.
• Lead design reviews and give thoughtful code reviews.
• Investigate production incidents, run root cause analysis and ship lasting fixes.
• Mentor mid-level engineers and share knowledge within the team.
