Senior Backend Engineer II

AI-native engineers. You use AI to raise your bar, not just move faster forming your own hypotheses, pressure-testing and verifying AI output, catching its errors, and taking full ownership of code quality regardless of how it was produced. You stay current with a fast-moving toolset.

Comfort in unfamiliar code. You ramp fast into systems you didn't write, reason about blast radius, and de-risk changes rather than hoping they work.

Architectural ownership & operational readiness. You design for scale and availability, anticipate failure modes, and build with monitoring and alerting from the start.

Ownership start to finish. Just because a project has been deployed doesn't mean it's done. You own outcomes, think end to end in terms of product and are customer obsessed

Collaboration you can trust. You let others speak, seek to understand their viewpoints, and are the kind of teammate people want to build with.

Product judgment. You care about the customer outcome, make the technical calls that produce a great product, and know when to challenge a spec.

Growth & learning. You actively improve your craft, your team, and how you work.

Proactivity. You act without being told, identify areas of improvement, and drive best practices.

Comfort with ambiguity. You can operate without a fully-specified problem and bring structure to it.

Organization & planning. You break large projects into smaller pieces that are easier to estimate and deliver.

Strong communication. Clear in writing and in person, across technical and non-technical audiences.
