Help Build the Backbone of Cybersecurity and the future of Human Risk Management. Mimecast is a global leader in cybersecurity, dedicated to protecting organisations and individuals from an ever-evolving threat landscape. Our mission is to deliver scalable, secure, and resilient solutions that empower our customers to operate with confidence. Beyond technical defences, we are pioneers in addressing human risk—tackling the most unpredictable element of cybersecurity by equipping people to be a critical line of defence through intelligent awareness, behaviour change, and proactive prevention.

We’re looking for a Mid-Level Java Engineer to join our Core Database team. This is not your typical backend role. You’ll help architect and build Java applications that operate at petabyte scale, enabling powerful, performant backend APIs and data processing workflows across PostgreSQL databases. These systems underpin Mimecast’s advanced cybersecurity and human risk management platforms.

Why Join: We’re building the backbone of Mimecast’s global infrastructure—systems that directly power how we combat evolving cyber threats and manage human risk. This isn’t just a job—it’s a chance to solve challenges at scale, grow your technical depth, and be surrounded by people who genuinely care about their craft and each other. If you’re looking for a place to stretch your skills and make a real impact, this is it.

What You’ll Do:

  • Engineer the Backbone: Design, build, and evolve high-performance Java applications that power critical backend services and interact with petabyte-scale PostgreSQL databases.
  • Innovate with Intent: Develop robust libraries and applications using a combination of proprietary frameworks, Spring Boot, and Micronaut—helping to standardize engineering excellence across teams.
  • Champion Performance & Security: Tune systems for scalability and resilience, ensuring that every line of code contributes to secure, reliable, and responsive services in alignment with Mimecast’s cybersecurity standards.
  • Drive Ecosystem Integration: Evaluate and implement tools that complement the Java/PostgreSQL stack, enabling observability, automation, and operational efficiency at scale.
  • Be a Technical Steward: Lead by example in documentation, code reviews, and troubleshooting—empowering teams across Mimecast with reusable patterns, clear processes, and proactive problem-solving.

What You’ll Bring:

  • Technical Excellence: At least 3 years experience with Java and modern frameworks like Spring Boot or Micronaut.
  • Data Fluency: Strong understanding of PostgreSQL, including database design, optimization, and performance tuning at scale.
  • Architectural Awareness: Familiarity with RESTful APIs, microservices, CI/CD pipelines, and distributed systems—plus an appreciation for designing systems that last.
  • Security Mindset: Awareness of secure coding practices and the fundamentals of cybersecurity, with a drive to build resilient, trustworthy software.
  • Collaboration: You thrive in a team-first culture, where sharing knowledge, giving thoughtful feedback, and solving complex problems together is the norm.
  • Curiosity & Drive: A growth mindset with a willingness to learn, adapt, and engage with both technology and people to create lasting impact.

What We Bring: At Mimecast, we don’t just build cybersecurity solutions—we build careers. You’ll be part of a culture that celebrates curiosity, creativity, and continuous learning. Our engineering teams thrive in a collaborative environment where knowledge sharing is second nature, and where your voice matters. We offer competitive compensation, including an extensive package of benefits covering health, wellness, and professional development. But just as important, we provide purpose: your work will directly help protect people and organisations from real-world threats—especially those stemming from human risk.

Career Growth Opportunities: This role is a launchpad. Whether your ambition lies in platform scalability, cybersecurity innovation, or people leadership, we’ll help you get there. You’ll gain exposure to cutting-edge technologies and high-scale systems, while working alongside domain experts who are invested in your development. We support upskilling, certifications, and lateral mobility, ensuring you have the runway to define your own growth path—at your own pace, on your own terms.

Manager's Working Style & Team’s Purpose: You’ll be joining a team that’s deeply focused on impact, quality, and integrity. Our leadership values transparency, autonomy, and frequent feedback—encouraging engineers to speak up, try new things, and learn through action. Expect daily interactions with peers and stakeholders, regular design discussions, and a rhythm of experimentation backed by best practices.

DEI Statement: Cybersecurity is a community effort. That’s why we’re committed to building an inclusive, diverse community that celebrates and welcomes everyone – unless they’re a cybercriminal, of course. We’re proud to be an Equal Opportunity and Affirmative Action Employer, and we’d encourage you to join us whatever your background. We particularly welcome applicants from traditionally underrepresented groups. We consider everyone equally: your race, age, religion, sexual orientation, gender identity, ability, marital status, nationality, or any other protected characteristic won’t affect your application. Due to certain obligations to our customers, an offer of employment will be subject to your successful completion of applicable background checks, conducted in accordance with local law.
