Company: Mortartec Location: Remote Experience: 1 – 2 Years

About Mortartec

Mortartec is building a next-generation CRM and data infrastructure platform for UK mortgage intermediaries. We are a fast-paced, high-autonomy startup on a mission to modernise how mortgage brokers manage their workflows, compliance, and client data. We operate a lean, agile environment where engineers are expected to own their systems end-to-end, think critically, and build scalable architecture.

The Role

We are looking for a highly capable, proactive Full Stack Developer to take ownership of core features across our platform. You will be expected to architect, build, and deploy end-to-end solutions, integrating complex third-party data APIs and delivering seamless, responsive user interfaces.

Key Responsibilities

• End-to-End Development: Architect and build scalable features from the database layer to the front-end user interface.
• API & Data Integration: Build and maintain robust integrations with third-party industry APIs (both REST and legacy SOAP) to power our core data engines.
• Infrastructure Management: Deploy, manage, and optimize our cloud infrastructure on AWS.
• Problem Solving: Independently research documentation, diagnose bugs, and deploy fixes without requiring heavy oversight.

The Tech Stack

• Backend: Java, Spring Boot
• Frontend: TypeScript, Next.js
• Infrastructure: AWS
• NoSQL databases

Who You Are

• Experience: 1 to 2 years of proven full-stack engineering experience.
• Startup Proven: You have successfully built and deployed end-to-end applications in a startup environment before.
• The Startup Mindset: You are a true self-starter. When faced with a blocker, you test hypotheses and bring solutions to the table rather than waiting for instructions.
• Product-Minded: You don’t just write code; you think about the user experience, application performance, and the most efficient way to solve a business problem.
