Lead-level backend ownership. AI-first delivery. Architecture decisions.
We are looking for a highly senior backend engineer who can operate at Lead Engineer / Architect level.
This is not a role for someone who only executes tickets. We need someone who can make architecture decisions independently, design systems with long-term scalability in mind, and turn ambiguous product needs into production-ready backend solutions.
This is a high-ownership role on a lean team. The default mode of execution is AI-first. Engineers use AI agents to accelerate research, planning, implementation, testing, and refinement, but ownership stays fully with the engineer. The person in this role must be able to use AI to move fast while maintaining strong judgment around architecture, correctness, security, performance, and reliability.
We are specifically looking for candidates who have already held responsibilities similar to Lead Engineer, or Architect in previous roles.
The work
Design and own backend services in NestJS and TypeScript, from schema to production
Make architecture decisions independently, with a focus on scalability, maintainability, and reliability
Build and maintain GraphQL APIs across a microservices environment
Own database design, optimization, and reliability in Postgres
Define technical direction, not just implementation details
Set and enforce quality standards across both AI-generated and manually written code
Translate ambiguous product needs into clear technical solutions
Contribute to system design, infrastructure decisions, testing strategy, and developer productivity
Operate in an AI-first workflow without compromising engineering standards
This is a fast-paced environment with real production stakes. You will be expected to move quickly, think at systems level, and make strong technical decisions with minimal hand-holding. If you are comfortable owning architecture and raising the technical bar in a high-accountability environment, this role is for you.
Bachelor’s degree in computer science or a related field, or equivalent experience.
Extensive hands-on experience with Node.js, Express.js or Nest.js
Hands-on Experience with GraphQL and TypeORM
Production experience with backend frameworks in high-scale environments.
Expertise in relational and non relational databases.
Advanced knowledge of MongoDB and/or PostgreSQL, with strong database design, administration, and optimization skills.
Strong experience designing and consuming RESTful and GraphQL APIs, and working with microservices architecture.
Proficient in client-side scripting, JavaScript frameworks, and handling cross-browser compatibility issues.
Experience with version control systems like Git and an understanding of CI/CD pipelines.
