Senior Backend Engineer (Node.js, AI-Native)

Job Type: Full-time
Work Mode: Work from Office (5 Days a Week)
Experience: 7+ Years
Role: Backend Node.js Developer / Founding Backend Engineer
Industry: Wealth Tech / FinTech / Consumer Technology

About the Role

We are looking for a highly experienced Backend Node.js Developer to join the founding technology team of a seed-funded Wealth Tech startup.

You will take end-to-end ownership of backend engineering, from architecture and greenfield development to scalability, reliability, integrations, and engineering standards. This role is suited for someone who has built production-grade B2C systems at meaningful consumer scale and is comfortable working in an early-stage, fast-paced environment.

Key Responsibilities

• Design, build, and own scalable backend systems using Node.js.
• Lead backend architecture decisions for greenfield and existing products.
• Define service boundaries, data flows, caching strategies, queues, and failure-handling mechanisms.
• Build and maintain robust APIs and backend services.
• Integrate with third-party platforms and external systems.
• Design efficient database schemas and optimize queries and application performance.
• Work with SQL and/or NoSQL databases and perform performance tuning.
• Build highly reliable and scalable systems for B2C products.
• Develop and ship products powered by LLMs and agentic workflows for end users.
• Establish backend engineering standards, coding practices, testing approaches, and system design principles.
• Collaborate closely with product and engineering teams in a rapidly changing startup environment.
• Use AI-assisted engineering tools across the software development lifecycle.

Mandatory Requirements

• 7+ years of hands-on backend engineering experience with Node.js.
• Strong experience building production-grade systems for B2C products at meaningful consumer scale.
• Proven ownership of backend architecture, including greenfield product development.
• Strong understanding of:
• API development
• Service-oriented architecture
• Data structures and algorithms
• Clean coding practices
• Scalability and reliability
• Caching and queueing
• Failure modes and system trade-offs
• Experience designing, developing, and maintaining APIs and backend services.
• Experience integrating external systems and third-party platforms.
• Strong database knowledge across SQL and/or NoSQL, including data modeling, query optimization, and performance tuning.
• Experience building and shipping LLM-powered products and agentic workflows for end users.
• Experience in B2C product companies/startups at meaningful consumer scale.
• WealthTech, FinTech, or high-growth consumer product experience is highly preferred.
• Stable career history with consistent tenure; frequent job-hopping will not be considered.
• B.Tech or Dual Degree (B.Tech + M.Tech / Integrated MSc/MS) from a Tier-1 Engineering Institute, specifically IITs. Candidates from other institutions will generally not be considered unless they have strong experience with top-tier product companies.
• Comfortable with a compensation structure where the company matches the candidate's current CTC without a salary hike and provides ESOPs.
• Candidates currently working at Stable Money are not eligible.
• Must be comfortable joining an early-stage, seed-funded WealthTech startup with a fast-paced environment and changing priorities.
• Must be willing to work from office, 5 days a week.
• Must be comfortable taking complete ownership of backend engineering and establishing engineering standards.

Preferred Qualifications

• AI-native engineering workflow with practical use of LLMs and agentic tools across the SDLC, including:
• System design
• Code generation
• Testing
• Debugging
• Documentation
