Opportunity Overview: This is a remote-first role that may require travel to Boston, MA for new hire onboarding and occasional in-person team meetings and company events. We are seeking a Senior Software Engineer to join our Engineering team. In this role, you will build and operate mission-critical healthcare technology that powers prior authorization for health plans covering 15+ million members. You'll work across the full stack — backend services, event-driven pipelines, and provider-facing web applications — to deliver systems that healthcare practitioners and clinical operations teams depend on daily. You'll partner closely with product, design, clinical, and platform teams to ship high-quality software in a complex, multi-tenant healthcare environment. This is an opportunity to solve distributed systems problems where engineering quality directly impacts patient access to care. What you’ll do: Own epic-level efforts end-to-end — from technical design and milestone decomposition through implementation, testing, and production deployment Design, build, and maintain services and applications across the full stack: backend (Java, Groovy/Grails), frontend (React, TypeScript), data (MongoDB), and event-driven messaging (Kafka) Proactively identify systemic technical risks including performance bottlenecks, reliability gaps, data consistency issues, and accumulated technical debt — proposing and executing solutions Evaluate technical approaches through design docs, pilots, and experiments — documenting decisions, tradeoffs, and outcomes to inform team direction Mentor engineers through code reviews, design discussions, and pairing — fostering a culture of ownership, learning, and technical excellence Lead technical design discussions, bringing data-driven analysis and written tradeoffs to resolve ambiguity and align cross-functional stakeholders Ensure launch readiness for your epics — comprehensive testing, rollout strategy, monitoring, and rollback plans — coordinating across teams when dependencies exist Collaborate with cross-functional teams (product, design, clinical, platform) to deliver high-quality experiences while balancing quality, delivery timelines, and operational constraints What you’ll need: 5+ years of professional software engineering experience with increasing scope and ownership Strong backend development experience using Java or Groovy, including designing and operating production-grade services Experience building modern web applications with React, JavaScript, and TypeScript Hands-on experience with NoSQL data stores (e.g., MongoDB), including schema design and query optimization Demonstrated ability to own and deliver epic-sized efforts — decomposing work into milestones, leading execution, and shipping with design-doc quality Experience building systems that integrate with external partners or upstream data sources, including APIs and event- or message-driven workflows (Kafka or similar) Proficiency with modern development practices including version control (Git), automated testing, and CI/CD pipelines Strong collaboration skills and ability to work effectively across team boundaries with product, design, and engineering partners Proven ability to mentor other engineers and elevate team quality through reviews and technical guidance Bachelor's degree in computer science, software engineering, or equivalent practical experience Experience in healthcare or life sciences industry, plus Familiarity with healthcare interoperability standards (FHIR, HL7), plus Experience with multi-tenant systems handling client-specific configurations at scale, plus Experience with API decomposition or monolith-to-services migration patterns, plus Hands-on experience with test frameworks such as Cypress, Playwright, JUnit, or Jest, plus Familiarity with cloud platforms (AWS) and distributed systems at scale, plus Pay & Perks: 💻 Fully remote opportunity with about 5% travel 🩺 Medical, dental, vision, life, disability in…
