Senior Software Engineer role at a world leading technology organisation operating across 27 countries, focused on .NET and C# with distributed systems, cloud native architecture, REST and GraphQL APIs.

About the Company

Our client is a world leading provider of financial markets infrastructure, operating at the heart of global financial and commodities markets from more than 60 offices across 27 countries. With over 5,200 people globally, their engineering teams build and maintain the technology that underpins price discovery, liquidity and data distribution at enormous scale.

Self-organising, cross-functional Agile teams, a genuine focus on cloud native architecture and automation, and a culture built around continuous improvement and knowledge sharing. This is not a company where engineers are told what to build and left to get on with it. They are involved in shaping technical direction from day one.

Why Work Here?

This is a company that is genuinely investing in Belfast. They have hired 12 engineers here already this year, not as a cost saving exercise, but because they are building serious engineering capability in Northern Ireland for the long term. To support that growth, they have just moved into a brand new office in Belfast city centre, purpose built to house the expanding team and give engineers the environment they need to do their best work.

The Belfast team is not a satellite office doing maintenance work. It is a core part of a global engineering organisation tackling complex, large scale problems with modern technology and real autonomy. If you are a senior engineer who wants to work at the intersection of world class technology and global financial markets, where the systems you build genuinely have to perform and the problems are as complex as they come, this is worth exploring. The work is real, the scale is significant, and the opportunity to grow within a technically serious organisation is genuine.

Key Responsibilities

  • Collaborate with Solution Architects and Principal Engineers to design and implement solutions aligned with IT strategy and technical vision.
  • Take ownership of engineering deliverables, ensuring quality, scalability and adherence to best practices.
  • Design and develop distributed, event driven, cloud native systems across the full software development lifecycle.
  • Build and maintain REST and GraphQL APIs to a high standard.
  • Drive continuous improvement by exploring new technologies, tools and methodologies.
  • Mentor and support team members, fostering a culture of learning and technical excellence.
  • Communicate progress effectively and proactively raise impediments to minimise delivery risks.
  • Build automated testing solutions for complex systems.

What You'll Need

Essential:

  • Proven experience designing, developing and maintaining distributed, event driven, cloud native systems.
  • Expertise in modern .NET technologies (.NET Framework and .NET Core) using C#.
  • Strong experience in API design and development across REST and GraphQL.
  • Solid understanding of relational database design and optimisation with MSSQL or MySQL.
  • Hands on experience deploying and managing cloud environments on AWS or Azure.
  • Comprehensive knowledge of the full SDLC with proactive involvement across design, development, QA and post release support.
  • Strong problem solving skills and ability to validate approaches through proof of concepts.
  • Experience building automated testing solutions for complex systems.
  • Ability to balance pragmatism with innovation and deliver high quality solutions under tight deadlines.

Nice to Have:

  • Proficiency in WPF application development.
  • Experience with AWS serverless architecture and microservices.
  • Familiarity with Java, JavaScript or React.
  • Understanding of TDD, BDD or similar testing methodologies.

Why Apply?

  • Salary up to £65,000.
  • Hybrid working with a Belfast base.
  • Part of a rapidly growing Belfast engineering hub, with 12 new hires already this year.
  • Work on business critical systems at genuine scale within a world leading organisation.
  • Real opportunity to influence technical direction and mentor engineers around you.
  • Self-organising, cross-functional Agile teams with a strong focus on automation and cloud native architecture.
  • Collaborative culture with a genuine emphasis on continuous improvement, experimentation and knowledge sharing.
  • Direct access to Solution Architects and Principal Engineers across a mature, technically serious engineering function.

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.

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.
