Senior Full-stack Software Engineer II (Frontend Leaning)

About the role

The right candidate for this role will:

• Lead frontend and fullstack implementation workstreams for carrier and enterprise partner integrations, owning the architecture and delivery of complex, partner-specific experiences from kickoff through production
• Architect and implement scalable UI layers and API integrations, setting patterns for partner-facing surfaces that can be reused and extended across future implementations
• Author high-quality RFCs with little guidance — identifying opportunities to turn one-off partner work into reusable, maintainable patterns that reduce build time for every implementation that follows
• Partner with Implementation Managers, Business Systems Analysts, and TPMs to translate business requirements into well-scoped, actionable technical plans
• Provide technical leadership in code reviews, delivering substantive architectural feedback that raises the quality bar across the team
• Champion a consumer-first mindset — designing integrations that are intuitive for partner users and maintainable for the next engineer who touches the code
• Champion engineering excellence through comprehensive testing strategies, including unit, integration, and end-to-end coverage for all partner deliverables
• Foster a security-first mindset within the team, identifying non-compliant code and ensuring reviewed contributions meet security requirements
• Define AI coding tool standards and best practices for the vertical, balancing productivity gains with quality guardrails and measuring effectiveness over time

Experience

• 5+ years of professional software development experience with significant depth in React and TypeScript
• Strong fullstack capability with professional experience in Go or Python
• Understanding of GraphQL architecture, including schema design, performance optimization, resolver patterns, and the ability to guide architectural decisions around API design
• Demonstrated ability to lead complex implementation projects end-to-end, including scoping, RFC authorship, and delivery with cross-functional partners
• Experience designing and consuming gRPC/REST APIs and building reliable integration layers between systems
• Proven track record of delivering accessible, performant, and production-ready frontend solutions that balance technical quality with delivery timelines
• Experience with modern frontend tooling including component libraries, build systems, and CI/CD pipelines
• Strong communication skills; comfortable presenting technical topics and tradeoff decisions to engineering directors, implementation managers, and non-technical business stakeholders
• Peer feedback that demonstrates this person is highly looked up to technically and as a collaborator
• Experience with distributed systems or microservices preferred
• Advocate for Continuous Integration / Continuous Delivery (CI/CD) and incremental software delivery
• Familiarity with AI coding tools (GitHub Copilot, Claude Code, Cursor) and the ability to evaluate AI-generated code critically for security, maintainability, and architectural alignment. Not just speed.
