About the Role

We are looking for Full Stack Engineers to join our engineering team. In this role, you will build and scale high-impact systems across our digital product landscape spanning client-facing web applications, workflow automation, and the internal platforms that power our core operations. You will play a key role in delivering high-quality software and solid technical foundations by designing seamless user journeys or architecting robust backend microservices in a regulated environment. We look for engineers with strong product mindsets who know how to strike the right balance: moving fast to deliver immediate business value while building reusable, scalable architecture for the long term. Additionally, AI is central to how we work, you will work hands-on with modern AI tooling to build intelligent features into our products and internal engineering workflows.

Responsibilities

  • Build and maintain high-quality client-facing applications, internal tools, APIs, and microservices across our stack.
  • Work seamlessly across modern frontend interfaces, backend services, asynchronous queues, and cloud infrastructure.
  • Partner closely with Product, Operations, Design, and Data teams to streamline complex workflows and build scalable software solutions.
  • Write clean, testable, maintainable code with a strong emphasis on security, data privacy, and operational reliability in a regulated environment.
  • Contribute to architectural improvements, testing, observability, and developer experience.
  • Shape technical direction, mentor peers, and elevate engineering standards across the team.

Requirements

  • Degree in Computer Science, Software Engineering, or a related field or comparable practical industry experience building production-grade software.
  • Strong hands-on experience with TypeScript, modern frontend frameworks (React, Next.js), and backend frameworks (Node.js, NestJS).
  • Practical experience building and operating both frontend web applications and production backend services (APIs, databases, serverless/lambdas).
  • Good understanding of REST APIs, GraphQL, authentication/authorization patterns (e.g., JWT), and service-to-service integrations.
  • Working knowledge of modern cloud infrastructure and tooling, such as AWS, Docker, Git, CI/CD, and production observability/debugging.
  • Strong analytical thinking with the ability to make pragmatic engineering and product trade-offs while taking ownership from idea to production.
  • Clear, open, and concise communication skills, with professional fluency in English.
  • Experience with distributed systems, event-driven architectures, queues, or asynchronous workflows.
  • Familiarity with additional backend languages (e.g., Python, Java, Kotlin).
