This role sits on our Data Platform team and owns integrations that feed our industry leading AMS product and our new data platform. I'm [Scott Roberts](https://www.linkedin.com/in/scottrobertsprofile/), Senior Manager, Engineering at Teamworks, and I lead this team. Our AMS ingests athlete performance data through roughly 150 RESTful vendor integrations, both webhook and polling based, pulling from wearables, force plates, GPS trackers, and other IoT hardware. As our product complexity and customer base have grown, so has the surface area of those integrations, and they need a senior engineer who will treat them as a first-class system rather than plumbing. Your initial focus will be learning and strengthening this existing C# .NET integration platform. Over time, you'll help lead the migration of these integrations to Python and our modern lakehouse, which will become the hub for hundreds of performance data pipelines across Teamworks products. This role sits at the intersection of both: keeping today's integrations reliable while designing how they move onto tomorrow's architecture. # The Role * Own the reliability, resilience, and observability of our existing performance vendor integrations, including day-to-day and on-call support for data gaps and mismatches * Maintain and improve our C# .NET integrations against vendor IoT APIs, and independently drive investigations with third-party vendor support teams when the problem originates on their side * Raise the bar on how well our team understands these integrations through documentation and knowledge sharing that outlasts any one engineer * Lead architecture and implementation for progressively porting our C# .NET integrations to Python and writing their data into our lakehouse * Strengthen the architecture and security posture of our integrations so we can deploy them into military IL4 and IL5 environments alongside our Tactical customers # What I'm Looking For ### What You Must Bring * 7+ years of software engineering experience with genuine mastery of C# and .NET, since that is what our existing integrations are written in and you will be working in them from day one * Demonstrated experience designing and building highly scalable distributed architectures on AWS, with Terraform fluency * Experience building or maintaining RESTful API integrations across different systems, including working fluency with the authentication protocols vendors actually use, OAuth 2.0 and the Authorization Code grant in particular * Comfort independently managing technical communication with third-party vendors when their API is the source of a problem, and a track record of shipping permanent fixes and improving the operational health of systems you inherit * US citizenship and US-based residency, required to support our Tactical and military customers ### Even Better If * You are well-versed in applying modern AI techniques across the software development lifecycle, we work this way and expect it to compound * You are strong in Python, or ready to be, since our integrations are progressively moving there * You have worked with IoT, wearable, or hardware-adjacent APIs where data quality issues originate outside your own system # Why This Role The integrations you'll own are how performance data actually reaches coaches, sports scientists, and military readiness staff, so the reliability work here has a direct line to people making decisions about athletes on the field and personnel in the field. You'll also help shape a lakehouse that will bring hundreds of performance pipelines together into a data asset that does not exist anywhere else in this industry, one that will feed customer analytics, ML models, and AI agents for years. If you want the depth of a complex existing system and the leverage of designing what replaces it, this is a rare combination. _This role is not eligible for sponsorship at this time._ _To all recruitment agencies: Teamworks does not accept agency resumes.
