Job description

The opportunity

Unity’s commerce systems power the business infrastructure behind our developer ecosystem — from licensing and subscriptions to in‑editor purchases and platform integrations. At the heart of this architecture is commerce services: backend‑for‑frontend (BFF) services and integrations that encapsulates business logic and service orchestration for our commerce platform.

The Core Commerce Backend team plays a pivotal role in unifying frontend experiences with backend systems such as commercetools, user identity, entitlement services, and pricing logic.

We are looking for a Backend Engineer to lead architecture and implementation efforts across Bridge’s Typescript‑based services. You’ll design reliable, scalable APIs and evolve our backend foundation to support a growing suite of commerce experiences.

What you’ll be doing

As a Senior Backend Engineer you will be expected to be able to:
Take a partially defined specification, understand the underlying requirement and problem and turn it into either a detailed specification for a less senior engineer or deliver the solution yourself.
Work closely with business, IT partners (business analysts and project managers) and the integration team to understand and solve business problems.
Design, implement and deliver highly scalable solutions based on modern cloud‑based architectures.
Support, optimize and automate our internal processes.
Take ownership of problems and find solutions.

What we’re looking for

We are seeking a Senior Backend Engineer who:
5+ years as a backend microservice engineer
Demonstrated experience designing and developing scalable and reliable microservices.
Proficient in TypeScript, particularly for service‑layer development
Experience in designing, implementing and executing unit tests
Experience with some of the other technologies used by the team: SQL/NoSQL, queues, alerting
Strong track record designing and implementing RESTful microservices
Comfortable taking ownership of system design and architectural decisions

You might also have

Familiarity with Google Cloud Platform (GCP) services (Cloud Run, Pub/Sub, etc.)
Experience deploying and operating services in Kubernetes
Hands‑on Experience as administrator or integrator with any of Salesforce, Zuora, Commercetools or similar headless commerce platforms
Experience with CI/CD pipelines like Github Actions
Experience with automated testing
Prior experience working with enterprise systems such as commerce, subscriptions, ERP, CRM or Supply Chain solutions.
Exposure to modern API paradigms and design patterns
