Software Engineer ll: Platform

Every engineer at Flexport ships code that moves real freight across 112 countries. The faster and safer they can do that, the faster the world's supply chains move. The PSI (Platform, Security & Infrastructure) team makes this possible: we build the paved path and tooling that hundreds of engineers around the world rely on every day to ship.

As a Software Engineer II, you'll own well-scoped projects within our developer platform, typically working with a small group of teammates. You'll talk to the engineers who use our tools, dogfood the platform, and build a solid understanding of the problems and goals behind your work. Then you'll design and ship improvements that remove friction. You'll get support and guidance from senior engineers on the team while building real ownership of your projects from start to finish.

• Building paved paths and self-serve tooling that make the right thing the easy thing.
• Building and supporting CI/CD pipelines (Buildkite, GitHub Actions), build tooling (Gradle, Bazel, npm/pnpm/bun, Go and Cargo) and artifact repositories (Artifactory, ECR, GitHub).
• Improving the backend and frontend developer experience through projects you scope and deliver.
• Contributing to our GraphQL and gRPC ecosystem: middleware, federation and schema sharing, CLIs, codegen, servers and clients.
• Contributing to our IAM solutions and primitives so that things are easy and secure by default.
• Helping engineers use and understand our container orchestration (Kubernetes, ECS) and observability stack (OpenMetrics, Datadog), so they can run, understand and debug their services.
• Gathering feedback from internal users, turning it into clear problem statements, and working with your team to prioritize what's worth building.

• 2-5 years of software engineering experience, ideally including time spent on developer platforms, internal tooling, or infrastructure that other engineers depend on.
• Full-stack curiosity: you're comfortable in a backend service and are building comfort across frontend build pipelines, Kubernetes manifests, and CI configuration.
• Hands-on experience with some of: a CI/CD system (GitHub Actions preferred), a container orchestrator (Kubernetes preferred), build tooling (more than one language is a plus), backend-for-frontend (GraphQL preferred), service-to-service communication (gRPC preferred), metrics, or artifact storage. You don't need all of them. You should be ready to learn the rest.
• A good grasp of problems and goals: you ask the right questions, understand who you're building for and why, and can explain how your work connects to broader team goals.
• Care for internal users: you treat engineers as customers, gather feedback, and check whether what you shipped actually helped.
• Ownership of your projects: you take a project from idea to production rollout, keep stakeholders informed, and raise risks early.
• Pride in fixing what's broken: you tackle tech debt in your area and help carry out migrations, with guidance on larger or cross-team efforts.
• Good communication: you can write a clear design doc for your project, take part in developer interviews, and keep your teammates up to date.
• A helpful attitude: you're the person who gets people unblocked and makes their work easier.
• Growth mindset: you seek out feedback, learn quickly, and are building toward broader scope and impact over time.
• Exposure to data-driven DevX development using metrics such as DORA.
• Experience with AWS.
• Familiarity with Identity and Access Management (IAM) concepts such as JWTs, OIDC and fine-grained authorization.
• Experience with Terraform.
