Backend Engineer Api Jobs

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. Edge Functions are server-side TypeScript functions, distributed globally at the edge - close to your users. They power use cases such as webhook receivers, AI inferences, OG image generation and real-time bots (Slack, Discord, etc). Built on top of Supabase Edge Runtime : an open-source, Deno-based runtime written in Rust that runs JavaScript, TypeScript, and WASM services. We want developers to be able to build truly global applications by distributing both compute and data globally. Infrastructure concerns like regions, cold starts, CPU and memory provisioning should fade into the background so developers can focus on iterating on business logic. We are looking for experienced and passionate engineers to help us go further in this vision. What You’ll Own Evolving Supabase Edge Runtime - an Open-sourced Rust-based host that runs the Deno isolate, manages the main/user runtime split, and enforces per-request memory and CPU limits. Implementing monitoring, alerting, and OpenTelemetry tracing across the runtime, then using that visibility to drive optimizations that improve latency and reliability of the service. Working closely with the Deno and other open-source teams, contributing to upstream and relaying our users' requirements. Participating in an on-call rotation to keep Edge Functions healthy in production. Help manage and improve features like scheduled functions, background tasks, WebSockets streaming, ephemeral file storage, and custom routing. Integrating functions more tightly with the rest of the Supabase stack - Auth, Postgres, Storage, and Realtime. Expanding functions to support more use cases (AI inference, MCP servers, hosting simple websites, URL shorteners). Improving the DX

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 Supabase manages millions of Postgres instances and is growing. We have strong teams across observability, release engineering, and incident management — and we're concentrating our reliability efforts into a dedicated SRE practice that ties the discipline together across the platform. You'll be embedded within Service Operations, and your primary job is to make every engineering team more reliable — not by owning their infrastructure, but by establishing the practices, frameworks, and feedback loops that let them own reliability themselves. You'll work across the org: sometimes setting the standard, sometimes pair-programming a fix, sometimes helping a team define their error budget, sometimes telling them it's exhausted. This role is ideal for someone who has a strong vision for how SRE should work and thrives in async, fast-paced environments where influence matters more than authority. What You'll Own Partner with service teams to define meaningful SLIs and SLOs grounded in customer experience, and build the error budget policies that turn them into engineering decisions Own and evolve the Operational Readiness Review (ORR) process — conducting reviews for new services and major changes across observability, alerting, runbooks, capacity, and graceful degradation Strengthen the incident-to-improvement pipeline: connecting postmortem findings to operational readiness gaps, identifying repeat failure patterns, and driving systemic fixes Act as the reliability expert teams pull in for architecture reviews, failure mode analysis, dependency mapping, and resilience design Identify and quantify operational toil across the org, and build or advocate for automation that eliminates it

About the Role We’re looking for a Postgres Deployment Engineer to join our PostgreSQL team and help elevate our PostgreSQL offerings. You’ll work closely with the PostgreSQL team, playing an instrumental role in technical decision-making and refining internal methodologies. This role is ideal for someone who thrives in async, fast-paced environments and is excited about building developer tools that scale to millions. The focus of this role is owning the stability and deployment of our products. You will act as a bridge between product and infrastructure teams to improve the reliability of deployments and upgrades. You will have co-responsibility for builds and deployments via our public supabase/postgres GitHub repository, which bundles features into Docker images and AWS AMIs for cloud and local use. What You’ll Be Responsible For Package software into our supabase/postgres repo using Nix (with flakes), and help us transition our packaging from traditional to Nix packaging more over time. Manage PostgreSQL lifecycles, ensuring timely major, minor, and extension upgrades. Expand platform release systems to allow developers to increasingly self-service. Optimize CI/CD and tooling, specifically expanding GitHub Actions, team tooling, and testing/release approaches. Resolve production issues by proactively identifying and fixing problems in customer deployments. Maintain best practices and tests to ensure enhanced stability and decreased deployment risks.

What You’ll Be Responsible for In this role, you’ll: Improve local development and the daily workflow Own local development environment stability; eliminate “works on my machine,” keep environments reproducible across teams, and make onboarding and setup self-service for every engineer Improve the daily editing experience, including IDE and editor tooling, extensions, and code search, indexing, and navigation that stays fast as the codebase grows Build paved roads: project scaffolding, templates, and golden-path workflows that make the right thing the easy thing Speed up build, test, and CI Improve our testing tooling and make sure it works well for engineers, including test orchestration, ephemeral end-to-end environments, and techniques like mutation and chaos testing that catch what ordinary tests miss Profile build and test performance, optimize CI pipelines, parallelize and shard tests, cache aggressively, and hunt down the bottlenecks that leave engineers waiting Integrate and optimize

Replit is the agentic software creation platform that enables anyone to build applications using natural language. With millions of users worldwide, Replit is democratizing software development by removing traditional barriers to application creation. About the Team Product Platform builds and owns the shared foundations the rest of Replit is built on, spanning the full stack so every other team can ship features safely and quickly: backend infrastructure, connectors, product primitives, and the frontend platform. Our work is high-leverage and horizontal: when our foundations are solid every other team moves faster, and the role gives you exposure across the whole of engineering. We are a small, collaborative team that values curiosity and clear thinking over pedigree, and we work in the open by bringing each other the problem rather than just the request. We care more about how you reason and build than the route you took to get here. About The Role As a Product Engineer , you can focus on frontend, backend, or full-stack work building the shared systems other teams depend on. The work is guided by a few simple questions: Are our shared systems fast, reliable, and cost-efficient as traffic grows? Are we making product development safe by default, consistent, and faster? Can a builder connect a third-party service once and have it work safely across every app they build? Are user-facing surfaces consistent and fast, with shared primitives teams can build on? Is our codebase easy to navigate, change, and extend, including for AI coding agents? What you’ll do Design reusable primitives and interfaces with clear contracts and documentation that other teams adopt Work directly with product teams to turn their friction into platform improvements Profile and instrument shared systems, then ship the improvements that move latency, cost, and reliability Harden systems against failure and abuse, and make safe defaults the path of least resistance Set technical direction in a
