• Conduct architectural and code reviews.
• Mentor engineers through clear technical discussions and constructive feedback.

• 8+ years of engineering experience with a bachelors degree, or 6+ years with a masters degree.
• Demonstrated experience designing and delivering significant production software systems.
• Strong full‑stack capability, including frontend architecture and backend services.
• Ability to explain technical tradeoffs and architectural decisions clearly.
• Experience solving complex engineering problems in a disciplined, high‑accountability environment.
• Ability to write software independently. Familiarity with AI‑enabled development tools is welcome but not a substitute for engineering judgment.

Preferred Experience

• Python
• TypeScript
• Complex data visualization
