Our client is a fast-growing, mission-driven organization transforming patient engagement at scale. They've built the leading platform powering communications for underserved populations, with proven impact reaching millions. Now they're looking for a seasoned backend engineer to lead their Messaging Team technical direction and mentor the next generation of engineering talent.

You'll own complex features end-to-end, drive architectural decisions that shape how millions of patient communications are delivered, and share team lead responsibilities with your peers. This is a highly visible, technically autonomous role with direct impact on health equity outcomes.

WHO WE'RE LOOKING FOR

• Deep experience building, maintaining, and scaling APIs and distributed systems
• Advanced SQL skills and comfort working with large, complex datasets
• Proven ability to independently own complex projects end-to-end and mentor junior engineers
• Data-driven mindset you rely on evidence, not intuition
• Excellent communicator (especially in fully remote environments)
• Passionate about mission-driven work and advancing health equity

BONUS POINTS

• Experience with Twilio, RCS, or MMS messaging platforms
• Familiarity with healthcare compliance (TCPA, consent workflows, carrier regulations)
• Tech stack: React, PostgreSQL, Google Cloud, Sidekiq
• Event-driven architecture or high-throughput message delivery pipelines

WHAT YOU'LL DO

• Own and drive the technical direction of key messaging platform features
• Design and build backend messaging systems (delivery pipelines, consent management, scheduling orchestration, API integrations)
• Mentor L2 engineers, lead technical design discussions, and set engineering standards
• Contribute to architectural decisions that shape messaging infrastructure at scale
• Participate in on-call rotations (PagerDuty) and help improve team processes
• Work cross-functionally with Product, Customer Success, and Data teams

YOUR IMPACT

• Month 1: Master the platform architecture and contribute to technical design discussions
• Month 3: Independently deliver complex features with meaningful impact on patient outcomes
• Month 6: Be recognized as a technical leader driving strategic initiatives across the engineering department
