The MCU Engineering team plays a critical role in delivering the scalable platform capabilities that power H1's products. Our engineers build the services, APIs, event-driven systems, and user experiences that transform complex healthcare data into fast, reliable, and intuitive products used by life sciences organizations around the world. Working across modern cloud infrastructure, distributed systems, and AI-enabled technologies, this team solves challenging technical problems at scale while partnering closely with Product, Design, and Data Engineering to continually improve the performance, reliability, and capabilities of our platform.

WHAT YOU'LL DO AT H1

As a Senior Software Engineer on our MCU team, you will own the delivery of complex product capabilities from technical design through production deployment with minimal guidance. You'll partner closely with Product, Design, and fellow Engineers to build scalable, high-performing applications that power H1's platform while helping shape technical direction across the team. This role is ideal for an engineer who enjoys working across the full stack, making architectural decisions, solving distributed systems challenges, and taking ownership of the quality and reliability of the software they build.

You will:

- Own features end-to-end from technical design through implementation, testing, deployment, and ongoing production support

- Develop and optimize APIs, backend services, and distributed microservice architectures.

- Design and optimize PostgreSQL schemas, queries, indexes, and database performance for large-scale applications.

- Build, maintain, and troubleshoot Kafka-based event-driven systems, including producers, consumers, consumer groups, replay strategies, and failure recovery.

- Develop and optimize Elasticsearch indexes, mappings, search queries, and performance for high-volume search workloads.

- Deploy, monitor, and support applications running in Kubernetes, including Helm charts, CronJobs, autoscaling, and production troubleshooting.

- Contribute to AWS-based cloud infrastructure and collaborate on Spark and EMR data workflows supporting the platform.

- Contribute to building and maintaining scalable full-stack applications across React frontends and NestJS backend services.

- Participate in architecture discussions, technical design reviews, and code reviews while helping establish engineering best practices.

- Partner cross-functionally with Product and Design to translate business requirements into scalable technical solutions.

- Continuously evaluate and improve system reliability, observability, scalability, operational performance, and infrastructure efficiency through thoughtful engineering decisions.

ABOUT YOU

You're a senior engineer who enjoys solving complex technical problems and taking ownership of the solutions you build.
