Senior Software Engineer, Platform Engineering

Senior Software Engineer, Platform Engineering At Midi Health, we're not just building a company; we're reclaiming midlife for women as a new beginning. We're the leading force in midlife women's healthcare, providing expert-designed, clinician-delivered, and insurance-covered care that's changing lives. As a company founded by women, for women, we're dedicated to helping every woman embrace midlife as a powerful new chapter. Join us, and you'll be part of a team that embodies our core values every single day. Location: Hybrid- San Francisco OR Palo Alto Office, Tuesday/Thursday ABOUT MIDI HEALTH Midi Health is the largest virtual care clinic for women in midlife navigating perimenopause, menopause, and other hormonal transitions. We combine expert clinicians, evidence-based protocols, and a modern technology platform to deliver care that has historically been underserved by the healthcare system. We're a fast-growing, mission-driven company building the infrastructure and products that define this new category of care. HOW WE WORK - Hybrid by design. Two days a week in-office (Tuesday and Thursday) in Palo Alto or San Francisco. We believe high-trust teams are built in person and scaled remotely. - AI-native engineering. We expect every engineer to be fluent with modern AI coding tools (Claude Code, Cursor, Copilot, and similar) and to actively push the frontier of how we build software. - Low-ego, high-curiosity. We approach disagreement with humility and technical rigor, not politics. We invest in each other's growth. - Outcome-oriented. We move fast, own our work end-to-end, and balance speed with the durability that healthcare demands. THE DIFFERENCE YOU WILL MAKE As Midi scales, the systems and services underneath our product need to scale with us — reliably, securely, and without slowing down the teams building on top. You'll build the core services, shared libraries, infrastructure, and developer tooling that every product engineer at Midi depends on, making it easy for them to ship fast and safely in a regulated environment. WHAT YOU WILL DO - Build and own core platform services — authentication, authorization, notifications, jobs/queues, feature flags, and the shared building blocks product teams reuse - Build developer productivity tooling — local dev environments, test infrastructure, CI/CD, preview environments, internal CLIs, and the paved paths that make the right way the easy way - Design and operate the cloud infrastructure and deployment platform product teams build on - Drive improvements in reliability, observability, performance, and cost - Harden our security and compliance posture in a HIPAA environment (encryption, access controls, audit, incident response) - Own on-call and incident response practices; turn incidents into durable improvements - Partner with product engineers to unblock them and shape technical direction across services - Use AI tools actively across services, infrastructure-as-code, tooling, and day-to-day engineering ABOUT YOU - 6+ years of experience building production services and/or infrastructure at scale - Strong hands-on coding skills (Python, Go, TypeScript, or similar) — you ship real services and tools, not just configuration - Seasoned at system design: deep understanding of distributed systems, APIs, data modeling, networking, storage, and cloud primitives (AWS/GCP) - Fluent with modern platform tooling: Terraform/IaC, Kubernetes or equivalent, observability stacks (Datadog, Grafana, OpenTelemetry), CI/CD - Product mindset toward internal users — you treat product engineers as customers and measure success by how much faster and safer they ship - Solid command of AI coding tools and comfortable adopting team workflows - Good mentorship instincts — you bring product engineers along on platform decisions rather than imposing them - Strong communicator who can explain tradeoffs to non-platform audiences - Low-ego, curious, humble NICE TO HAVE ...
