As a backend developer, you will be working on internal services that communicate with other internal services via HTTP. When communicating with other companies, you’ll be implementing whatever their specification needs, which to date has included technologies like SOAP, AS4, email, JSON over HTTP, XML over HTTP, and SFTP. Our services are written in Python and Scala. Our Scala code uses the Typelevel ecosystem extensively. Our Python code uses FastAPI and Pydantic extensively. We use open source technologies to underpin our backend services, things like Apache Kafka, Postgres, nginx, and Kubernetes. Our infrastructure is expressed as code using OpenTofu (the FOSS fork of Terraform).

What you’ll have:

- General interest in technology and problem‑solving; diligence and thoughtfulness.
- Experience/expertise in the following (in rough priority order):
- Scala, using an effect system like Cats Effect.
- Domain modelling.
- HTTP and REST APIs.
- Writing robust, fault‑tolerant and observable software.
- Apache Kafka and event‑based architecture.
- Postgres or other relational databases.
- Kubernetes.
- Python.
- Plus experience in the following would be a bonus:
- Terraform, OpenTofu.
- CircleCI.

What you’ll do:

- You and the Market Gateway team will continue to build a Market Gateway product for global clients and territories.
- You will be involved in designing and developing recent features for the Market Gateway.
- You will be interacting with members of other teams that use the Market Gateway to solve problems that they are having.
- You will be keeping the lights on: responding to incidents, triaging bugs, coding up fixes, and deploying and monitoring the product continuously.




- You will be working closely with the Market Gateway Tech Lead and Product Manager.
- You will be writing, responding and implementing tech proposals.
- You will be reading and writing documentation for Market Gateway.
