About the Role:

As a Senior Full-Stack Software Engineer, you will be a key member of a dynamic engineering team, responsible for the design, development, testing, and deployment of robust and scalable web applications.

This position offers the opportunity to work on innovative projects within a highly regulated environment.

Responsibilities:

  • Develop scalable backend services (Node.js, Type Script) and performant user-facing applications (React).
  • Design extensible system architectures and make pragmatic trade-offs that balance performance, security, and maintainability.
  • Own full lifecycle delivery of complex features, from architectural planning and API design to UI implementation and post-release observability.
  • Ensure high availability and observability of our services; improve alerting, logging, and incident response across the stack.
  • Set and uphold strong engineering standards via code reviews, technical mentorship, and design documentation.
  • Partner with product, design, and stakeholders to align engineering with business goals and user needs.
  • Lead technical design reviews and system decomposition efforts across teams.
  • Proactively identify risks and gaps in operational or architectural resilience, and drive durable improvements.
  • Collaborate closely across engineering to reduce knowledge silos and ensure continuity in critical systems through cross-training and documentation.

Requirements:

  • Bachelor’s or Master’s degree in Computer Science, Software Engineering, or related field (or equivalent experience).
  • 8–12 years of software engineering experience, with deep expertise in backend systems (Node.js, Postgre

    SQL) and experience with modern front-end frameworks (React, Type Script).
  • Proven track record
