Sr. Principal Platform Engineer

Hi. We’re Hummingbird. We’re elevating patient access so patients can get healthcare how, when, and where they need it. We partner with healthcare systems to transform how patients access care, enabling their providers to focus on what matters most – caring for patients. By managing patient access as a technology-enabled service, we help health systems stabilize costs and improve patient experience while creating good jobs that attract and retain talent in the industry. Our team of experts is obsessed with the connection between the people, processes, and technology that make healthcare organizations hum. Join us and help build the healthcare experience we want for our communities, our families, and ourselves. Summary Responsibilities About the Role Build the platforms that power patient access, and help a growing engineering team do the best work of their careers. As a Sr. Principal Platform Engineer at Hummingbird, you’ll be the technical anchor for the team that builds our production platforms. You’ll spend most of your day hands on in the code: designing and building features, making the architecture decisions that shape our applications, and reviewing the work of earlier-career engineers so the whole team grows stronger. You’ll bring deep, independent engineering skill to the work and use AI tools to move faster without relying on them to do the thinking for you. You’ll work closely with your team and partner regularly with IT Security and Data and Analytics to keep our systems connected, reliable, and built to last. For a few engineers just starting their careers, you’ll be the person who helps them understand not just what we build, but why we build it the way we do. What You’ll Do Build and maintain the core of our production platforms, spending most of your time hands on in the codebase. Own the architecture decisions for our production applications, choosing where logic should live and how systems should connect. Review pull requests and designs from earlier-career engineers, reinforcing standards for quality and consistency. Mentor engineers who are early in their careers, helping them understand the reasoning behind technical decisions. Develop across the full stack, working in both front-end and back-end code as the work requires. Partner with IT Security and Data and Analytics to align on data access, integration, and system design. Troubleshoot complex technical issues, from failed integrations to system reliability problems, and resolve them at the root. Use AI-powered development tools to speed up delivery while keeping full ownership of quality and design judgment. Document decisions and tradeoffs so the team can build consistently and maintain systems over time.

What Helps You Shine Please note that we use both your resume and your written and oral communication throughout the hiring process to understand your fit for this role. Thoughtful, clear responses help us see your attention to detail, your professionalism, and your ability to communicate with care, all skills that are essential for success on our team. Expectations for Focus & Presence To support patients and each other, this role requires your full attention during scheduled work hours. Our Outside Employment Policy doesn’t allow overlapping work or “job stacking,” so any outside work must happen fully outside your Hummingbird schedule. We’re a camera-ready team, and you’ll need to be on camera during training and when needed during the workday after training ends. We value connection, teamwork, and being present, which is what keeps our patients safe and our team supported. If that’s what you’re looking for, you’ll feel at home here. If you’re hoping to hold another job during the same hours, this job won’t be the best match. Growth at Hummingbird This role is a key step in our engineering career path. You’ll receive support, collaboration, and real technical ownership from day one, with the chance to shape our platforms, grow the engineers around you, and take on broader architectural influence over time. At Hummingbird, we believe good jobs should lead somewhere, and that starts here. #LI-JF1 Please Note: The seniority level of this position may be adjusted during the recruitment process based on candidate skills and experience. A Note on Authentic Interviews We believe the best hiring conversations are real ones. Notes are welcome, and jotting things down during the call is completely fine. What we ask is that you don’t use AI tools or similar assistance to generate your responses in real time. We’re genuinely trying to get to know you: how you think, how you communicate, and what you’ve experienced. That connection matters to us, and it’s hard to find when answers are scripted rather than interactive. We’re a team that makes healthcare more human. We’d love to meet the person behind your application. The Hummingbird Approach We value a team that brings diverse perspectives and experiences to the work we do.
