Job summary

Alter Domus is seeking an API Developer to build platform APIs using TypeScript and Python, owning Kubernetes deployments, Helm charts, and GitOps workflows. You’ll design OpenAPI contracts, write clear docs, and ensure backward compatibility while delivering reliable APIs for internal developers.

You will work across deployment, observability, and security aspects, using OpenTelemetry, Docker, and GitHub Actions to ship robust, scalable services in a production environment.

Qualifications

• 3–5 years building production APIs; proficient in TypeScript and Python.
• Strong API design with OpenAPI, REST conventions, versioning and error handling.
• Kubernetes engineering; capable of debugging pods, not just deploying.
• Hands-on with Docker and Helm, CI/CD with GitHub Actions.
• Familiar with OAuth2, OIDC and JWT authentication patterns.
• Experience with relational databases and data modeling.
• Daily use of AI tools to explore options and speed up routine work.
• Autonomous, able to own a platform component end-to-end.

Responsibilities

• Build APIs in TypeScript and Python that other teams rely on.
• Design with OpenAPI contracts and clear documentation to aid adoption.
• Package services as containers and deploy to Kubernetes with Helm charts.
• Maintain CI/CD pipelines (GitHub Actions) for tests, builds and releases.
• Configure routing, authentication, rate limiting and versioning at the API layer.
• Instrument services with OpenTelemetry for traces, metrics and logs.
• Collaborate with security and operations to align with controls.

The Role

We are looking for an API Developer who builds the platform APIs other teams depend on, and runs them in production. You will write the code in TypeScript and Python, and you will own the Kubernetes deployments, pipelines and monitoring that keep it running.

These are platform APIs, so your users are other developers. That changes how you work: an API only succeeds if it is easy to adopt. We want someone who puts themselves in the user’s shoes before shipping.

Building Platform Capabilities

• Design and build APIs in TypeScript and Python that other teams use as building blocks
• Treat other developers as your customers. Talk to them, understand how they will integrate, and design for that
• Write clear OpenAPI contracts, useful documentation and error messages that actually help the caller
• Pick sensible defaults so the common case works with minimal setup
• Keep versioning and backwards compatibility in mind, so adopting your API today does not create work for someone tomorrow

Deployment & Operations

• Package services as containers and deploy them to Kubernetes, writing and maintaining your own Helm charts
• Ship through GitOps with Flux, so what is in the repository is what is running in the cluster
• Build and maintain CI/CD pipelines in GitHub Actions for automated testing, building and release
• Configure the API layer in front of your services: routing, authentication, rate limiting and versioning
• Instrument your services with OpenTelemetry so traces, metrics and logs show you a problem before a user reports it
• Debug issues across application code, infrastructure and networking

Working in the Team

• Take a problem with its context and come back with a proposal. You will not be handed a solution to implement
• Review other people’s code and take review well on your own
• Work with security and operations to keep services aligned with our controls

Qualifications & Skills

Must Have

• 3–5 years building production APIs, comfortable in both TypeScript and Python
• Good grasp of API design and OpenAPI (REST conventions, versioning, error handling, pagination)
• Real Kubernetes experience: you can debug a pod that will not start, not just deploy to a cluster someone else built
• Hands‑on with Docker and Helm
• CI/CD experience, ideally GitHub Actions
• Familiar with authentication patterns such as OAuth2, OIDC and JWT
• Working knowledge of relational databases
• You use AI tools every day, to get up to speed on unfamiliar technology, to explore options before committing, and to move faster on routine work, while still understanding what you ship. Tell us how you use them.
• Able to work autonomously, raise questions early and own a piece of the platform end to end

Nice to Have

• API gateway experience such as Kong, a plus and not a requirement. We will train the right person
• GitOps tooling such as Flux or Argo CD
• OpenTelemetry and an observability stack (Prometheus, Grafana, Loki, Tempo or similar)
• Event‑driven architectures and messaging (Kafka, RabbitMQ, SQS, Azure Service Bus)
• Cloud platform experience (AWS or Azure)
• Terraform basics, enough to provision your own databases, caches and queues
• GraphQL
• Previous platform engineering or developer experience work
• Background in financial services or another regulated industry

Mindset

We are looking for someone who:

• Thinks about the developer on the other end of the API, and asks \"would I want to integrate with this?\" before shipping
• Enjoys building the foundations other people build on
• Is curious and self‑directed, you research what you do not know rather than waiting to be taught
• Uses AI as a normal working tool, not a novelty, and stays critical of what it gives back
• Is comfortable owning a service from the API contract through to production
• Prefers asking a good question early over guessing quietly

WHAT WE OFFER

We are committed to supporting your development, advancing your career, and providing benefits that matter to you.

Our industry‑leading Alter Domus Academy offers six learning zones for every stage of your career, with resources tailored to your ambitions and resources from LinkedIn Learning.
