About UpHill
At UpHill, our mission is to increase clinical capacity so healthcare professionals can focus on what matters most — the patients. Healthcare teams are either stretched thin by work that can be automated or weighed down by waste that can be avoided. UpHill's intelligent automated platform uses hospital data and patient conversations to turn chaos into useful and efficient interactions.
We build conversational AI agents, intelligent clinical pathways, and care orchestration tools that empower clinicians to work at their full potential — deployed across leading hospitals in Europe, with 100K+ lives impacted and over 1 million clinical interactions mediated. UpHill Route is a certified Class IIa Medical Device.
We're a team of curious and creative people who believe technology should enhance — not replace — the work of healthcare professionals. If you're excited about making a real impact in one of the most meaningful industries in the world, you just might be an Uphiller.
Today we're looking for a Senior Platform Engineer to join our platform team — a hybrid role sitting at the intersection of DevOps and core backend engineering. You'll architect and operate the cloud infrastructure that powers our product suite, build and maintain backend services, and own the internal developer platform that helps our engineering teams move fast and safely.
Stack Used
AWS — ECS/Fargate, Lambda, SQS, EventBridge, S3, RDS, CloudFront, Cognito, VPC/IAM — Terraform
Docker · Docker Compose
GitHub Actions (CI/CD)
Python · Java / Spring Boot (backend services)
PostgreSQL · Redis
DataDog · CloudWatch (observability)
Responsibilities
Architect and maintain cloud infrastructure: Build and operate secure, scalable AWS infrastructure using Terraform across a multi-account architecture. Own it from design to production.
Drive CI/CD excellence: Design, maintain, and improve deployment pipelines that enable fast, safe, and reliable releases across all engineering teams.
Contribute to backend services: Work directly on backend Python and Java/Spring Boot services when needed — the platform team is not purely infrastructure; you build things too.
Own observability and reliability: Improve monitoring, logging, and alerting across the stack. Ensure teams have the visibility they need to operate and debug production systems confidently.
Elevate developer experience: Identify and remove friction in the development workflow — better tooling, cleaner local environments, faster feedback loops, reusable infrastructure modules.
Optimize for cost and performance: Continuously evaluate infrastructure spend and service performance, proposing and implementing improvements.
Collaborate across engineering: Work closely with product and AI engineering teams to translate infrastructure needs into robust, scalable solutions.
Mentor and grow the team: Promote a culture of ownership, operational excellence, and continuous learning. Help junior engineers level up.
Ownership mentality: You ship and maintain what you build.
Autonomous but collaborative: Capable of owning initiatives end-to-end while working effectively with cross-functional teams.
Product-focused: You understand why reliability, scalability, and developer speed directly impact business outcomes.
Main Requirements
MSc/BSc in Computer Engineering, Software Engineering, or a related field
Minimum 5 years of hands-on experience with AWS (ECS/Fargate, Lambda, VPC, IAM, RDS, SQS, CloudFront, etc.)
Strong proficiency in Terraform for infrastructure-as-code
