  • Work alongside the Principal Engineer to deliver new features from design through to deployment
  • Focus on robust back-end development, ensuring stability, scalability, and performance
  • Contribute to DevOps practices and infrastructure management (AWS, Terraform)
  • Design and implement reliable third-party integrations (finance systems, IoT, hardware, and more)
  • Collaborate with Product (PM/UX) to ensure solutions are practical, scalable, and user-centric
  • Build and refine API endpoints and data handling across the platform
  • Write clear documentation and contribute to internal knowledge-sharing
What You Bring
  • 5+ years working as a Back End Developer, ideally within SaaS or complex integration environments
  • Strong experience with Java (Java 24 preferred) and functional programming concepts
  • Solid understanding of cloud architecture (AWS S3, Lambda) and infrastructure as code (Terraform)
  • Proficiency working with databases and storage systems (SQL, CRUD operations)
  • Strong knowledge of Spring Security and best practices for security layering

Bonus Points For
  • Experience launching or scaling SaaS products
  • Knowledge of OAuth2 protocols and authentication flows
  • Familiarity with compliance, permissions, or operational modules in B2B platforms
  • Previous exposure to fast-moving, startup-style environments

This is an opportunity to work on an industry-first SaaS platform, building features that have immediate real-world impact. If you're back-end focused but excited by the chance to shape infrastructure and DevOps too, we'd love to hear from you.
