## About the Role

You'll likely be someone who:

 * Has strong software engineering fundamentals.
 * Enjoys tackling unfamiliar technical challenges.
 * Thrives in ambiguous environments rather than waiting for detailed instructions.
 * Has excellent communication skills and enjoys collaborating with developers and stakeholders.
 * Can identify problems independently and drive solutions through to completion.
 * Brings a product mindset to engineering challenges.
 * Is passionate about developer experience, platform engineering, automation or internal tooling.

## Description

Build the Internal Developer Experience for One of the World's Largest Financial Institutions

We're looking for highly capable Software Engineers to join a newly formed engineering team responsible for transforming how thousands of developers build, deploy and operate software across a global enterprise.

This is not a traditional application development role.

You'll be helping shape a next-generation internal developer platform that aims to provide the same seamless experience developers expect from products such as Heroku, Render, Railway and Coolify. The goal is simple: reduce complexity, remove friction and create an industry-leading developer experience at scale.

The platform is in its early stages, making this a rare opportunity to influence architecture, tooling, workflows, usability and developer adoption from day one.

What You'll Be Doing

 * Building services, tools and capabilities that improve the software delivery experience for engineers across the organisation.
 * Identifying pain points in developer journeys and driving solutions from concept through to implementation.
 * Improving and evolving internal platforms and user interfaces.
 * Working closely with engineering teams to understand challenges and remove barriers to productivity.
 * Helping create intuitive, self-service experiences that minimise manual intervention and support.
 * Influencing technical direction, platform usability and engineering best practice.
 * Acting as a self-starter within a small, high-impact team with significant autonomy.

Technology

The environment is deliberately technology-agnostic. The team is looking for strong engineers who are excited by learning and solving problems, rather than specialists tied to a single stack. Current technologies include:

 * Java
 * Kotlin
 * Node.js
 * React
 * AWS
 * GCP

You'll also encounter technologies such as:

 * Go
 * Rust
 * .NET
 * Messaging platforms and distributed systems technologies

Exposure to these technologies is beneficial but not essential. Mindset and adaptability are valued far more than ticking every box.
