About the Role

We're looking for a Senior Back-End Engineer to lead the design, development, and evolution of backend systems and cloud infrastructure. This is a high-impact role with ownership over backend architecture, data modeling, cloud environments, and DevOps workflows that power the core platform.

In this role, you'll work hands-on with TypeScript and NestJS to deliver scalable backend services, while owning AWS infrastructure end-to-end. You'll collaborate closely with other engineers, contribute to architectural decisions, and help shape backend standards as the platform grows.

What You'll Do

  • Lead backend architecture and implementation using TypeScript and NestJS
  • Design, develop, and maintain scalable backend services and platform APIs
  • Drive data modeling, schema evolution, and query optimization in Postgres
  • Design and implement clean, reliable, and well-documented REST APIs
  • Own AWS infrastructure end-to-end, including ECS, Lambda, S3, API Gateway, SQS, VPC, IAM, KMS, and CloudWatch
  • Manage multi-environment setups, CI/CD pipelines, deployments, and secure role-based access
  • Improve local development workflows, tooling, environment parity, and system reliability
  • Support platform integrations, backend reliability, and operational excellence
  • Mentor other engineers and help define backend best practices and standards
  • Collaborate with cross-functional teams to deliver stable, production-ready systems

What We're Looking For

  • Senior-staff level experience in backend software engineering
  • Strong expertise in TypeScript, NestJS, and backend system design
  • Deep experience with AWS cloud architecture, infrastructure patterns, and scaling strategies
  • Strong understanding of IAM, security best practices, and cloud cost/performance trade-offs
  • Solid experience with Postgres, including data modeling and performance optimization
  • Experience designing and maintaining RESTful APIs
  • Experience owning production systems, debugging complex issues, and shipping reliably
  • Comfort operating autonomously in a fast-moving environment
  • Strong communication skills and a collaborative, ownership-driven mindset
  • Willingness and ability to mentor other engineers and influence technical direction

What It's Like to Work Here

  • Remote-friendly environment with collaboration across regions and time zones
  • A team that values quality, ownership, accountability, and thoughtful engineering
  • Opportunities to lead foundational platform work and influence long-term architecture
  • Supportive leadership that encourages growth, learning, and initiative
  • Clear ownership of systems and the ability to shape the next version of the platform
