Sr Software Engineer, PBM Member Experience

About Rightway Healthcare

Rightway is on a mission to harmonize healthcare by delivering superior care navigation and pharmacy benefits management (PBM). We leverage innovative technology, combining human expertise with cutting-edge tools to simplify the healthcare journey for employers, employees, and their families. By addressing key healthcare challenges, we ensure that our members receive high-quality, cost-effective care.

Role Overview

We're looking for a Senior Software Engineer to join the PBM Member Experience team at Rightway. This team owns the surfaces our members interact with: mobile (React Native), web (React), and the APIs that power them (Node.js/NestJS, gRPC, PostgreSQL).

This isn't a "write features to spec" role. Our senior engineers own initiatives end-to-end: they shape architecture, define technical direction, unblock other engineers, and drive delivery across multiple workstreams. You'll partner directly with product and design to make scope and sequencing decisions, not just implement them. You'll be the person your teammates come to when they're stuck, and you'll build the documentation, patterns, and tooling so they get stuck less often.

We ship in TypeScript across the entire stack. We're an AI-native engineering team that uses AI tooling daily in our development workflow and expects our senior engineers to lead adoption, establish best practices, and help the team get better at working with these tools.

What You’ll Do

• Own and drive technical initiatives
  • Lead the architecture and delivery of major features across mobile, web, and API layers, from design through production
  • Make architectural decisions (service boundaries, data modeling, API contracts) and document them so the team can build on them
• Elevate the team around you
  • Mentor mid-level and junior engineers through pairing, code review, and design discussions. Not just catching bugs, but teaching patterns
  • Transfer knowledge proactively, mentoring engineers to discover the "why" with a deep foundation of how systems are built
  • Establish and maintain coding standards, testing strategies for your initiative area
• Build and maintain production systems
  • Design and build gRPC APIs using NestJS
  • Work across React Native (mobile) and React (web) to deliver cohesive member experiences
  • Define and implement service communication patterns using Protocol Buffers and gRPC
  • Own observability for your systems. Maintain Datadog monitors, Sentry error tracking, and know when something is wrong before users report it
• Shape how we work
  • Contribute to architecture decisions in cross-team forums
  • Drive AI-native development practices by establishing workflows, sharing findings, and helping the team use AI tools effectively
  • Identify and raise risks early, including timeline slippage, technical debt, vendor reliability issues, and compliance gaps
  • Coordinate across team boundaries when your work touches other services or teams

Who You Are

• 5+ years of professional software engineering experience, with demonstrated progression into technical leadership
• Deep full-stack fluency. You've built and maintained production systems across frontend (React), mobile (React Native), and backend (Node.js/NestJS) layers
• Strong data modeling instincts. You think carefully about schema design, normalization trade-offs, and how data decisions cascade through a system
• Experience with service-oriented architectures. You've designed APIs, defined service boundaries, and dealt with the realities of distributed systems (failure modes, composition patterns, contract evolution)
• Comfortable with ambiguity. You can take
