Platform Engineer - Compute Capacity

About Supabase Supabase is the Postgres development platform, built by developers for developers. We provide a complete backend solution including Database, Auth, Storage, Edge Functions, Realtime, and Vector Search. All services are deeply integrated and designed for growth. About the Role We are seeking a platform engineer to join our Compute Capacity team. This team owns the capacity plan that keeps compute supply ahead of demand across every region we operate in — the forecasting, buffer policy, and provisioning systems that make sure a project never runs into a wall it didn’t know was there. You’ll work on the systems that turn a capacity plan into provisioned reality: reservation acquisition, fleet reconciliation, and the automation that keeps what we’ve committed to in sync with what we’re actually running. You’ll help build the metrics and alerting that let capacity problems surface months out, on vendor lead time, rather than at the moment someone needs the room. You’ll design, build, and operate systems that are both robust and highly automated — helping us hold the right buffer at the right cost, catch drift before it becomes a shortage, and give every team a single, trustworthy view of how much room we have across the millions of databases we manage. What You’ll Be Responsible For • Help build and maintain the capacity plan that keeps Supabase’s compute supply ahead of demand across regions and instance families • Support buffer policy by modeling headroom targets and their cost tradeoffs for review and sign-off • Build and maintain automation that turns the capacity plan into provisioned reality — reservation acquisition and top-up, fleet reconciliation, drift detection between committed and running capacity • Extend our infrastructure as code for capacity-relevant provisioning • Instrument capacity: build and maintain metrics for saturation, reservation coverage, idle buffer, forecast error, and provisioning latency • Build and tune capacity alerting so headroom, quota, and reservation issues surface months out rather than at the moment of impact • Support the demand gate — helping intake large customer commitments, launches, migrations, and new regions so they reach the plan before they reach the fleet • Contribute to mitigation projects: right-sizing, instance-family migrations, autoscaling improvements, workload consolidation • Help drive down compute cost per database through right-sizing, placement, and commitment coverage work • Participate in capacity incident response and post-incident follow-through You Might Be A Good Fit If You • Have 5+ years across infrastructure engineering, SRE, platform, or capacity engineering, ideally at SaaS or cloud infrastructure scale • Have production software engineering experience — you’ve owned and operated a service, not just a notebook. Comfortable in modern languages like TypeScript, Python, and Go • Are comfortable working against forecasts and assumptions that are incomplete, and can revise your work as those assumptions change • Have experience with Infrastructure as Code (Pulumi or Terraform) • Have built or maintained observability for systems you own — metrics that answer real questions and alerting people trust (Prometheus/Grafana, CloudWatch, or similar); • Have solid working knowledge of AWS EC2: instance families and generations, purchase options, capacity reservations, and quota mechanics • Have some financial fluency — you understand reservation economics and the basic tradeoffs between coverage, utilization, and cost • Communicate clearly across audiences, from engineers to finance stakeholders What We Offer • Fully Remote We hire globally. We believe you can do your best work from anywhere. There are no Supabase offices, but we provide a WeWork membership or co-working allowance you can use anywhere in the world. • ESOP Every team member receives ESOP (equity ownership) in the company. We want everyone to share in the upside of what we’re building together. • Tech Allowance Use this budget to set up your ideal work environment—laptop, monitor, headphones, or whatever helps you do your best work. • Health Benefits Supabase covers 100% of health insurance for employees and 80% for dependents, wherever you are. Your wellbeing and your family’s health are important to us. • Annual Off-Sites Once a year, the entire company gathers in a new city for a week of connection, collaboration, and fun. It’s a highlight of our year. • Flexible Work We operate asynchronously and trust you to manage your own time. You know what needs to be done and when. • Professional Development Every team member receives an annual education allowance to spend on learning—courses, books, conferences, or anything that supports your growth. About the Team Supabase was born-remote and open-source-first. We believe our globally distributed team is our secret weapon in building tools developers love. • ~400 team members • 60+ countries • 20+ languages spoken • Over $1B raised (including our $500M Series F) • 540,000+ community members We move fast, build in public, and use what we ship. If it’s in your project, we probably use it in ours too. We believe deeply in the open-source ecosystem and strive to support—not replace—existing tools and communities.
