Principal Java Developer - Fully Remote The Opportunity

Ocho is partnering with a fast-growing, product-led fintech that's building out a brand-new Development Centre from the ground up to deliver an innovative Greenfield platform.

As a Principal Java Developer, you'll be hands‑on in designing and developing backend, service, and portal systems that power secure, scalable payment processing. You'll work with a modern stack, agile practices, and an engineering culture that values autonomy, technical excellence and collaboration - without the red tape.

• Be part of a team shaping a new product suite from concept to release.
• No legacy systems - you'll work with modern tools, frameworks, and automation from day one.
• A culture that empowers engineers to focus on solving complex problems, not battling process.
• Continuous improvement built into the DNA - from BDD to CI/CD pipelines and beyond.
• Full ownership of your deliverables from design through deployment.

• Design, develop, and maintain backend systems focused on performance, scalability, and security.
• Understand client and partner needs, translating them into high-quality, innovative software solutions.
• Contribute to all stages of the SDLC - from requirements analysis to release and post-deployment verification.
• Collaborate across engineering teams to ensure deliverables are technically accurate, testable, and on time.
• Lead technical discussions around architecture, tooling, and process improvements.
• Support deployments to internal test environments and production data centres.
• Mentor and guide team members, promoting best practices in software delivery.

• 8+ years' experience in backend engineering, ideally within a Fintech or high-availability environment.
• Expert‑level Java / J2EE development, including design patterns, OO design, and refactoring.
• Proven experience delivering secure, scalable, high-quality services in production.
• Strong understanding of REST API design (JAX-RS, RESTEasy, OpenAPI, Swagger).
• Familiarity with CI/CD, automation, and Behavioural Driven Development (BDD).
• Excellent communication, analytical, and problem-solving skills.

• Salary up to £100k + annual bonus
• Fully remote working (UK-based)
• Industry-leading benefits package
• A modern engineering environment with autonomy, trust, and cutting‑edge technology
