The Role:

As a Software Engineer, you'll work across the design, architecture and build of enterprise systems that support trading, operations and risk functions.

  • Own software quality, efficiency, cost and operational resiliency
  • Participate actively in cross-company technology efforts to support wider business goals
  • Work closely with heads of business lines and front office trading on system implementation and maintenance
  • Contribute to testing strategy, including unit, integration and functional testing
  • Support CI/CD pipeline development and containerised, automated deployments

What You'll Need:

Essential:

  • At least 2 years of experience in a technical role (fresh graduates also welcome to apply)
  • Bachelor's or postgraduate degree from a recognised university in a related field
  • Experience working in a cloud environment
  • Strong computer science fundamentals
  • Understanding of software architecture and design
  • Exposure to cloud infrastructure such as AWS or another major cloud platform
  • Database design and management experience, ideally PostgreSQL

Desirable / Nice to Have:

  • Extensive Java experience, ideally including Spring Boot
  • Experience with queue-based systems such as Kafka

Why Apply?

  • Circa £40,000 to £55,000, dependent on experience
  • On-site working in Belfast
  • High level of autonomy, with your voice heard by management
  • A culture that recognises substance over form and rewards performance
  • Genuine support for long-term development and growth

How to prepare for a job interview at Ocho

Brush Up on Your Coding Skills

For a full-time software engineering role, it's crucial that we stay sharp with our coding abilities. Expect technical questions that might involve solving problems on the spot or discussing algorithms. Practise on platforms like LeetCode or HackerRank to get comfortable with the types of questions that often come up.

Know Your Tools and Frameworks

Make sure we’re well-acquainted with the tools and technologies listed in the job description. Familiarise ourselves with any specific frameworks or programming languages mentioned. If Ocho uses React or Node.js, for instance, be ready to discuss how we’ve used them in previous projects or coursework.

Showcase Your Projects

Bring along a portfolio that highlights our best work. This could be code samples, GitHub repositories, or any side projects we’ve built. Make sure we can talk through our thought process for each project, especially the challenges we faced and how we solved them—this shows our problem-solving skills in action.

Prepare for Behavioural Questions

While technical skills are key, full-time positions also require cultural fit. Be ready to discuss our previous experiences and how we handle teamwork, conflict, and deadlines. Brush up on the STAR method—Situation, Task, Action, Result—to clearly articulate our past experiences when discussing how we've contributed to a team.
