Implementation Engineer

Company Description Today, when you go to your doctor and get referred to a specialist, your doctor sends out a referral and tells you, “They’ll be in touch soon.” So you wait. And wait. Sometimes days, weeks, or even months. Why? Because too often providers are overwhelmed with the painstakingly tedious work required to get paid by insurance companies. Powered by proprietary models, Tennr handles the complex paperwork that gets patients through the door and providers paid, helping operators get patients the right care, at the right time, in the right setting.

Role Description As an Implementation Engineer, you’ll build, test, and support automation solutions for Tennr’s most complex customers: large-scale health systems, national provider groups, and strategic partners. This is a hands-on, highly technical, customer-facing role that demands strong judgment, quality discipline, and the ability to deliver on committed timelines. You’ll work alongside an Embedded Solutions Engineer who owns solution design, while you own the build, the testing, and the health of the account after go-live. You’ll pressure test designs before you build them, ship work that holds up under real operational load, and keep multiple build threads moving at once. This role sits within Embedded Solutions and works directly with Solutions Engineers, Account Partners, Product, and Engineering.

Responsibilities

• Build, test, and optimize customer workflows on Tennr’s platform against the Solutions Engineer’s architecture

• Pressure test designs up front and flag logic gaps, edge cases, and downstream effects with a proposed fix

• Run multiple concurrent build threads while keeping timelines and status clear for internal stakeholders

• Test your own work end to end, including edge cases and failure scenarios, and prevent regressions on live enterprise deployments where a bug has immediate operational impact

• Own post-go-live support for your accounts, handling customer communication and issue resolution

• Stay with the customer past go-live to build on top of the core workflows, expand automation into new areas, and evolve the build as their business changes

• Write well-scoped product tickets and collaborate with Product and Engineering to improve the platform

• Work in an agile cadence (sprints, grooming, estimation) and give an accurate forward read on capacity and at-risk dates

Qualifications

• 3+ years building, testing, and deploying software integrations for external, enterprise customers

• A degree in Computer Science, Engineering, Data Science, Information Systems, or Industrial/Operations Engineering is preferred. Equivalent experience is welcome

• Comfortable working directly in code across APIs, data workflows, and system integrations, and able to debug your way through an unfamiliar system

• Fluency with agentic and AI-assisted workflows

• Strong QA discipline: you test your own work thoroughly and catch issues at build time

• Clear communicator with customers and internal teams

• Experience running work in an agile cadence (sprints, grooming, estimation)

• Able to manage several concurrent workstreams and own a date

• Comfortable with ambiguity and fast-paced, high-ownership environments

• Based in New York City area (or open to re-location) and able to work on-site 4 days/week

Nice to Haves

• Experience with healthcare systems and data, such as EHR integrations, HL7/FHIR, revenue cycle, or referral and authorization workflows

• Experience with enterprise go-lives

• Advanced fluency with agentic and AI-assisted development. Coding agents are a core part of how you work, you know how to scope and direct them through non-trivial builds, and you can spot when the output is wrong before it ships

• Familiarity with workflow automation, RPA, or enterprise integration platforms (e.g., Workato, UiPath)
