Who You Are
You are a Senior Back-End Engineer joining a new product initiative. You will be responsible for building and maintaining scalable, reliable back-end systems that power web and mobile applications.
You'll work closely with engineers, product managers, and infrastructure teams to design systems that are secure, high-performing, and built to scale. Your work will directly influence the architecture and evolution of new product offerings.
What You'll Do
- Design, build, and maintain scalable back-end services, APIs, and data systems that support web and mobile applications
- Architect reliable, secure, and high-performance server-side solutions
- Collaborate with front-end engineers, product managers, and infrastructure/DevOps teams to deliver end-to-end features
- Ensure systems are built with best practices around code quality, testing, observability, and deployment
- Contribute to architectural decisions across microservices and event-driven systems
- Work with modern cloud and containerized environments to support scalable deployments
- Leverage caching, messaging, and data pipelines where appropriate to improve system performance
- Stay current with modern back-end engineering practices, distributed systems, and emerging technologies
- Use AI tools and automation thoughtfully to improve engineering productivity and decision-making
What We're Looking For
- 7+ years of back-end engineering experience, including time in senior or lead roles
- Strong experience building APIs and services using Node.js, TypeScript, and frameworks such as NestJS or Express
- Solid understanding of SQL databases; exposure to NoSQL is a plus
- Experience working with microservices and event-driven architectures
- Familiarity with cloud platforms (AWS, GCP, or Azure)
- Experience with Docker and Kubernetes or similar containerization/orchestration tools
- Working knowledge of caching strategies and messaging systems (e.g., Kafka or similar)
- Experience using API tools such as Postman and version control systems like Git (or Bitbucket)
- Strong engineering fundamentals around scalability, reliability, and system design
Bonus Points
- Experience working in early-stage or fast-moving product environments (zero-to-one builds)
- Exposure to fintech, trading, brokerage, lending, or financial systems
