Elevate the technical judgment of engineers around you through design reviews, architectural guidance, and mentorship
Troubleshoot and drive resolution of the hardest cross-system issues in our stack
Participate in on-call rotation to ensure system reliability and rapid issue resolution
Engage directly with product and executive stakeholders to assess feasibility, cost, and risk of strategic initiatives
Drive architectural decisions and technical direction across multiple teams and systems
Directly build and ship software that tackles the hardest, most ambiguous technical problems in our stack
Set the engineering standard through your own code, design patterns, and technical approach
Own cross-cutting concerns: scalability, reliability, security posture, and cloud cost efficiency
Identify converging efforts across teams and consolidate before they become compounding tech debt
Design and evolve system architectures for our B2B portals, collaboration tools, internal platforms, and customer-facing APIs
Evaluate build-vs-buy decisions, technology bets, and system design tradeoffs with direct business impact

Strong proficiency across multiple languages and comfortable ramping quickly on ones you haven't used before. Our stack includes Go, TypeScript, C#, and React
Proven ability to own the full software development lifecycle, from requirements and design through construction, testing, deployment, and production operations
Experience with cloud architecture and resource-efficient infrastructure design at scale
Full ownership mentality that extends beyond your own code to the health of systems, culture, and teams around you
Strong understanding of SQL databases, caching layers, event-driven architectures, and data pipeline design
Pragmatic technical judgment that optimizes for the right solution given real constraints, not the theoretically perfect one
Track record of driving technical alignment across teams with competing priorities
Enthusiasm for leveraging AI-assisted development tools and emerging technologies
Ability to translate between business language and technical language fluently, in both directions
Nice to have:
Experience with healthcare data standards (HL7, FHIR) or regulated industry environments
