Staff Software Engineer - Platform Architecture

Remote (US) · Full-time

Company Overview

b.well is solving healthcare’s fragmentation problem with our FHIR-based health data management platform. The platform connects data from EHRs, wearables, portals, and other sources, while our intelligence engine personalizes the consumer experience. By simplifying the complex healthcare ecosystem, we make it easy and convenient for consumers to engage and take action—whether it’s scheduling care, setting reminders, accessing health data, and more. For our clients, this means better health outcomes, operational efficiency, and stronger consumer engagement.

Position Overview

The Architecture team defines how that platform is designed and built. We set the patterns, contracts, and standards the rest of engineering builds on, run technical design reviews, and take on the hardest, most cross-cutting systems ourselves. We're hiring a Staff Software Engineer to own work like event-driven data integration on Kafka, large-scale distributed processing, and the API and federated GraphQL layer behind our SDKs — and to partner on making AI a dependable part of the platform.

This is a hands-on role. You design these systems, you build them, and you help operate them in production. You work horizontally across teams rather than inside a single product squad, so the patterns and services you create show up everywhere. The hard problems here are about scale, correctness, distributed-systems behavior, and the real-world messiness of healthcare data.

What you'll do

* Design and build event-driven distributed systems on Kafka: orchestrator and worker services, schema and contract governance (AsyncAPI, CloudEvents), idempotent consumers, sagas and event choreography, and config-driven pipelines that onboard new data sources without code changes. * Own API architecture at scale across REST and a federated GraphQL gateway (WunderGraph Cosmo) that powers our SDKs, including schema compo...
