About the Role :

We are looking for a Senior Backend Engineer with strong Node.js expertise to join the founding technology team of an early-stage consumer product startup. You will own backend engineering end-to-end, from architecture and greenfield development to production reliability and engineering standards.

What You'll Do :

- Design and build production-grade Node.js services and REST APIs from the ground up.

- Own backend architecture, including service boundaries, data flow, caching, queueing, failure handling, scalability, and reliability.

- Make architecture decisions for greenfield systems while balancing performance, reliability, and engineering constraints.

- Build and integrate APIs with third-party platforms and external systems.

- Design efficient data models and optimize SQL/NoSQL databases, queries, and application performance.

- Develop and ship LLM-powered and agentic product features for end users.

- Use LLMs and agentic development tools across the software development lifecycle, including design, coding, testing, debugging, and documentation.

- Diagnose production issues and take ownership of system reliability and performance.

- Establish engineering standards, best practices, and scalable development processes.

Requirements :

- 6+ years of hands-on Backend Engineering experience with strong production experience in Node.js.

- Experience building backend systems for B2C products at meaningful consumer scale.

- Proven ownership of end-to-end backend architecture, including greenfield systems.

- Strong understanding of API development, service-oriented architecture, data structures, algorithms, and clean coding practices.

- Experience designing, developing, and maintaining APIs and backend services, including third-party integrations.

- Strong experience with SQL and/or NoSQL databases, data modeling, query optimization, and performance tuning.

- Experience in B2C product companies/startups, preferably in WealthTech, FinTech, or high-growth consumer technology.

- Proven experience building and shipping LLM-powered products and agentic workflows for end users.

- Stable career history with consistent tenures across organizations.

- Comfortable working in an early-stage, fast-paced startup with evolving priorities.

- Willingness to work from office 6 days a week and take complete ownership of backend engineering.

- Comfortable with a compensation structure where the company matches current CTC and provides ESOPs, without a salary hike.

- Candidates currently working at Stable Money will not be considered.

Preferred :

- Strongly AI-native engineering workflow, using LLMs and agentic tools across the SDLC.

- Engineering degree from a Tier-1 engineering college.

- Previous experience as a Founding Engineer or early-stage technology team member.
