Job Description
THE ROLE
This is not a promotion title for a mid-level developer. This is for the engineer who decides how systems are structured who owns architecture, not just implementation within it.
You'll work directly with the CTO and product leadership to translate ambiguous business problems into system design. You'll define scope, propose architecture, own decisions end-to-end, and be accountable for outcomes.
If you've always worked within someone else's architecture, this isn't the role. If you've been the person who defines that architecture keep reading.
WHAT YOU'LL OWN
System architecture: service design, inter-service communication patterns, event-driven design, and data modeling independently, from first principles
Technical requirement gathering directly with product and business stakeholders you define scope, not wait for a spec
AWS infrastructure architecture: compute, networking, data layer, and delivery
Real-time financial data pipelines on Kafka are critical to our core product
Data layer design across PostgreSQL (relational/transactional) and MongoDB
Backend engineering standards the rest of the team follows
Build vs. buy decisions with documented, defensible tradeoff reasoning
WHAT "SENIOR" MEANS HERE
You've designed distributed systems end-to-end not just contributed to someone else's design
You lead technical discussions with non-technical stakeholders; you don't wait for a ticket to start thinking
You identify over-engineering in your own work and in others' and course-correct without prompting
You make confident architectural decisions with incomplete information and articulate your tradeoffs clearly
You've shipped systems you designed, not just systems you inherited
REQUIRED STACK
Node.js AWS Kafka PostgreSQL MongoDB all required in production
REQUIREMENTS
45 years of backend engineering; minimum 2 years in architecture-owning roles
All stack technologies used in production environments not side projects
Product company background not services, outsourcing, or agency
Based in Bangalore or willing to relocate immediately
YOU'LL THRIVE HERE IF
Small team dynamics give you energy less process, more ownership
You're comfortable being the most accountable person for technical calls
You treat over-engineering as a problem, not a signal of seniority
Regulated or data-sensitive environment experience
YOU'LL STRUGGLE HERE IF
You need architectural direction before you can start
You've been technically strong but have always deferred design decisions upward
You've never led stakeholder conversations to define technical scope
WHY NOW
Stack Wealth is approaching Series A. The systems you design will scale with the company. The technical foundations you lay today will define the platform for the next three years.
