Job Summary
Architect and ship production code on Spring Boot + Kotlin and React + TypeScript while coaching a small, focused engineering team. Shape technical direction by defining architecture, tooling, and testing strategy from scratch, ensuring robust, scalable foundations for mission-critical public safety software used by police, fire, and rescue organizations. Integrate modern AI coding assistants and agentic tools as core daily workflow components to accelerate design, review, and delivery. Lead hiring, 1:1s, and direct feedback to cultivate a high-performance environment where senior engineers thrive.
Required Qualifications
- 7+ years of professional software engineering experience
- senior-level depth in both Spring Boot + Kotlin and React + TypeScript
- Proven experience leading engineers — formally as a manager/tech lead, or informally as a senior who consistently raises the bar around them
- Demonstrable experience starting a product codebase from zero and growing it into something that other engineers can sustainably build on
- Strong architectural judgment: API design, data modeling, modularization, testing strategy, and knowing when not to add complexity
- Comfort across the stack: REST APIs, MongoDB (or other document databases), build pipelines, observability, and modern frontend patterns (hooks, state management, type-safe APIs)
- AI literacy is a must — you actively use AI coding assistants (Claude Code, Copilot, Cursor, or similar) in your daily workflow and can show how they change the way you design, build, review, and ship
- Excellent communication in English, both written and verbal — you can write a clear RFC and run a productive code review
- A proactive, ownership-driven mindset and a real care for code quality, reliability, and team health
- Motivation to work on software that has real-world impact, globally
Desired Qualifications
- Experience in regulated, safety-critical, or high-availability domains
- Experience hiring and onboarding senior engineers
- Familiarity with cloud platforms (AWS/GCP/Azure), Kubernetes, and modern CI/CD
- Experience introducing AI tooling and practices at a team or org level
