MCS Group is thrilled to be partnering with a fast-growing, forward-thinking tech company that's building a globally-used product utilised across multiple industry sectors. With significant investment secured and major scaling plans already underway for 2025, they're looking for a Principal Java Developer to play a pivotal role in the evolution of their core software platform.

As their Principal Java Engineer, you'll join a small yet collaborative, high-performing software engineering team and take ownership of a critical product area. You'll be at the forefront of architecture and development while mentoring the next generation of software talent and less experienced software engineers -all under the guidance (and support) of a visionary Head of Engineering and CTO.

If you're looking for a role where you can lead, innovate, and make a real impact, this could be the move for you.

Why You Should Apply:

• Be part of a compact, agile team that punches well above its weight
• Lead in a fast-paced environment where your ideas and impact will be visible
• Shape best practices and push cloud-native solutions forward
• Enjoy fast-tracked career progression in a well-funded business which is scaling

What You'll Be Doing:

• Architect and build complex, scalable applications using modern Java and AWS services
• Set and uphold engineering standards across the team
• Collaborate closely with product and hardware teams to deliver secure, high-performance systems
• Mentor and support junior engineers, fostering a culture of continuous learning
• Stay at the cutting edge-bring new ideas, tools, and methods into the team

What We're Looking For:

• Deep experience with Java (latest versions), Spring Boot, and microservices
• Strong hands-on knowledge of event driven systems
• Experience of working in scaling tech companies and/or product-focused tech start-ups will be highly advantageous
• Natural leadership skills with a passion for mentoring and team development
• A problem-solver with a drive for clean, modern software engineering

What's in it for You:

• Salary up to £90,000
• Share options
• Flexible hybrid working (2 days in office per week)
• Huge opportunity for growth and progression
