Principal Software Engineer - Document Processing (US Remote)

TREND Health Partners is a tech-enabled payment integrity company. Our mission is to facilitate collaboration between payers and providers for mutual benefit and waste reduction, ultimately improving access to healthcare. We achieve this by aligning the common goals of payers and providers and fostering collaboration through a shared technology platform and seamless workflows.

Joining TREND Health Partners means becoming part of a dynamic, growing organization that promotes a collaborative and innovative work environment. Our comprehensive compensation package includes competitive salaries, highly valued health insurance, a 401(k) plan with employer match, paid parental leave, and more.

The Principal Software Engineer will lead the development of innovative, scalable software solutions that support complex document review workflows for healthcare payers and providers. This role requires a deep understanding of modern web application architecture and cloud-native backend systems. The engineer will collaborate closely with architects, product, QA, and cloud teams to drive system-wide design decisions, optimize platform performance, and deliver new capabilities to our customers. 

The ideal candidate will possess strong technical leadership, a hands-on approach to coding, and the ability to mentor other engineers while ensuring alignment with architectural standards and business goals. 

• Documented professional software engineering experience, with a track record of shipping and operating production systems — we're looking at what you've built and owned, not just tenure.
• A habit of taking ownership of the problem space, driving the solution, and standing behind your decisions. We don't do blame here — when something goes wrong, we own it, learn, and move forward.
• Strong Go experience, particularly for backend/service work.
• Hands-on experience with document processing at scale — you understand PDF structure and edge cases well enough to reason about performance, reliability, and failure modes across variable real-world input.
• Experience designing and implementing metrics and observability for production systems — deciding what should be measured and building it, not just consuming dashboards someone else built.
• Comfort with AWS serverless patterns: Lambda, Step Functions, ECS, and event-driven architecture generally.
• Solid database fundamentals — schema design, query optimization, troubleshooting performance issues.
• A track record of driving something from an ambiguous starting point to a finished product.
• Ability to work independently and make sound calls without a lot of oversight.
• Strong communication — you'll need to explain tradeoffs to engineers and non-engineers alike.
• Experience mentoring engineers day to day — not just leaving comments in code review, but actively growing the people around you.
• Comfort handling sensitive data (PHI) responsibly and in line with HIPAA requirements.

• Proficiency in C++ — not required, but a plus given some of our high-performance pipeline segments are written in it.
• Interest or experience in Rust — not currently in use, but on the table for future performance-critical pipeline work.
• Hands-on OpenSearch (or Lucene-based search) experience. This space doesn't have a dedicated owner today — if it's a strength of yours, there's a real opportunity to take charge of it.
• Experience with document-centric pipelines (OCR, classification, extraction, or similar).
• Healthcare or payment-integrity industry background.
• Comfort using agentic coding tools as part of a modern dev workflow.
  
  A Note on Culture
  
  We're a laid-back team — plenty of memes, self-managed accountability, low ceremony. We care more about whether the work is good and the pipeline is reliable than about how you got there. We're Mac-shop, and we lean on modern tooling (including AI-assisted coding) without letting it replace engineering judgment.
