Graduate Software Developer 

Role Overview

We’re seeking a curious, proactive Junior Developer to help extend OCU One, our bespoke workforce-management platform. You’ll work shoulder-to-shoulder with senior engineers—writing code, crafting tests and learning how we ship reliable, maintainable software that powers thousands of field activities every day.

From your first sprint you’ll pick up clearly scoped tickets, contribute to peer reviews and execute test cases that safeguard quality. You’ll receive mentorship in Ruby on Rails, SQL tuning, containerised development and modern CI/CD workflows while gradually taking on more complex tasks.

Expect exposure to the whole engineering lifecycle: analysing user stories, coding and QAing features, reviewing logs after release and proposing incremental improvements. If you thrive on learning by doing—and want to see your code make a tangible operational impact—this is the perfect step-up role.

1. Feature Development & Maintenance

• Build small, well-defined Rails (or similar) components and assist in bug fixes.
• Write basic unit and integration tests for new code.
• Document changes clearly in pull-request descriptions.

2. Code Quality, Testing & Peer Review

• Follow established coding standards; seek feedback and iterate quickly.
• Execute functional / regression test scripts and log clear defect reports.
• Participate in pair-programming and learn to give constructive PR comments.

3. Learning & Mentorship

• Shadow senior developers during design sessions and spike investigations.
• Complete agreed learning paths (framework, database, testing tools).
• Present occasional “what I learned” demos at team show-and-tells.

4. Tooling & Process Participation

• Use Git branches, commits and pull requests as part of daily workflow.
• Run local containers / dev scripts; raise issues and suggest tweaks to improve Developer Experience.
• Update tickets and contribute to sprint ceremonies.

5. Support & Continuous Improvement

• Reproduce simple issues in test/staging; help verify fixes during releases.
• Monitor basic application logs and surface anomalies to the team.
• Suggest documentation updates and lightweight process improvements.

Skills and Experience:

Essential Skills

• 0–2 years commercial or strong academic software-development exposure.
• Familiarity with Ruby (or another OO language) and web-framework basics.
• Basic knowledge of Git commits, branching and pull-request flow.
• Understanding of unit / integration testing principles; able to write simple RSpec or Minitest cases.
• Clear communicator—comfortable asking questions and explaining findings.
• Demonstrable enthusiasm for continuous learning and problem-solving.

Desirable Skills

• Exposure to Ruby on Rails and relational databases (PostgreSQL / MySQL).
• Experience with containerised development (Docker) or cloud hosting.
• Familiarity with CI pipelines (GitHub Actions, Jenkins, etc.).
• Knowledge of front-end tech (HTML/CSS/JS) or mobile (Flutter) basics.
• Participation in open-source projects or coding communities.
• Background in field-service, construction, or workforce management platforms.
• Experience working on in-house developed platforms or enterprise software
