Job description

MPL Technology is a founder-led Insurtech business building a suite of in-house, mission-critical platforms that support insurance claims, legal case management, underwriting, and data-driven decision making.

We are looking for a Full Stack Software Engineer to play a central role in the design, development, and evolution of our core technology platforms. You will work across the full application lifecycle, from user-facing interfaces and APIs through to cloud-hosted services and data pipelines.

The role spans a wide range of impactful projects, including the development of a proprietary legal and claims case management system, the ongoing enhancement and scaling of our claims platforms, and the integration of underwriting, actuarial, automation, and AI-driven capabilities into everyday business workflows.

You’ll work closely with technical and non-technical stakeholders to translate complex operational processes into scalable, maintainable software. This is a hands-on role offering real ownership, influence over technical direction, and the opportunity to shape products that are actively used in a regulated, real-world environment.

What you’ll be doing

• Design, develop, and maintain in house applications, covering front-end, back-end, and cloud infrastructure.
• Build and enhance in-house business and case management platforms, ensuring alignment with ISO 9001, ISO 17020, ISO 17024, and ISO 17025 quality management standards.
• Develop and integrate APIs, services, and data pipelines to support internal and external systems.
• Implement AI-enabled features and automation to improve data processing, analysis, and operational efficiency.
• Translate business processes and user requirements into scalable, maintainable software solutions.
• Collaborate closely with cross-functional teams such as client partnership directors and operational managers to understand end-user requirements and translate them into leading solutions.
• Continuously assess and improve application performance, security, reliability, and scalability.
• Contribute to architectural decisions, technology selection, and best practices.
• Maintain clear technical documentation and contribute to knowledge sharing across the team.
• Provide technical input and recommendations to the CTO to support strategic decision-making.
• Support user adoption by contributing to training materials and system documentation where required.

What We’re Looking For

• Minimum of 3 years’ professional experience as a Full Stack or Backend Developer.
• Bachelor’s degree in computer science or a related discipline (or equivalent practical experience).
• Strong experience with C# and .NET (.NET Framework and/or .NET Core).
• Solid understanding of RESTful APIs, databases, and data modelling.
• Hands-on experience with Microsoft Azure, including deployment and cloud-based services.
• Familiarity with AI or data-driven solutions (experience integrating AI services is a plus).
• Understanding of secure application development and best practices.
• Exposure to blockchain technologies is advantageous but not essential.
• Strong problem-solving skills with excellent verbal and written communication. You will be comfortable working in a fast-paced start-up environment with a high degree of ownership.

What we offer:

• Additional annual leave with service, plus additional paid day leave for your birthday.
• Wellbeing packaged including free PT sessions, private medical insurance & health cash back plan.
• Part-funded or fully-funded professional qualifications, with length of service.
• Free parking, pension, full time hours of 35 hours a week.
