Company DescriptionAt Octo Health, we’re building the first AI health copilot for people with chronic conditions. A companion that truly understands patients, learns from their health over time, and helps them act before things spiral.Healthcare today is fragmented and reactive. We’re flipping that paradigm. Chrono Health puts people back in control of their health, helping them understand their condition, improve it, and live with more quality of life and peace of mind. This isn’t just another health app. It’s the start of a movement, where patients finally have a partner they can trust, and where technology serves the people it matters most to. RoleYou’ll join a team building a microservices platform on GCP, powering a product that combines healthcare and AI.You’ll start by shipping features. Quickly, we expect you to take ownership of services, decisions, and outcomes.We use AI as a core part of how we build. Planning with AI, generating code, reviewing outputs, refining approaches. Your role is to guide, validate, and push quality forward.This is not a corporate role. We move fast, we figure things out, and we expect people to step up.Tech stackJava 25, Spring Boot 4, MavenPostgreSQL, FlywayKafka, RedisGCP, GKE, API Gateway, Cloud SQLGitHub, GitHub Actions, HelmFirebaseWhat you’ll doDesign and build backend services using Java and Spring BootWork on a microservices architecture with Kafka and RedisBuild and evolve APIs, data models, and workflowsCollaborate on system design and technical decisionsDeploy and operate services on GCP using KubernetesContribute to CI/CD pipelines with GitHub ActionsUse AI as a core part of development, planning work in structured docs before implementationWork in an agentic flow, plan, generate, review, and refine until production readyValidate and improve AI generated code, ensuring quality and correctnessWhat makes you a great fit3+ years of backend experience with Java and Spring BootComfortable working in a fast moving environment with ambiguityStrong ownership mindset, you don’t wait to be told what to doExperience or familiarity with cloud and KubernetesYou already work with AI in a structured way, planning before coding, using documentation to guide execution, and validating outputs with tools like Claude Code, codex, gemini ; cursor, antigravity, etcFluent EnglishWe work from Lisbon, on-site. We are an early stage startup building from scratch. That means long hours, fast pace, and a lot of ownership. This is not a 9 to 6 role, and it is not meant to be.This is an early stage role with meaningful equity. You will have real skin in the game and a direct impact on what we are building.If you want to be part of something from the ground up, take ownership, and help shape the outcome, let’s talk.
