ENG-002 Engineering Full-time

Senior Engineer / Tech Lead – Backend & Platform

Chennai, India (Hybrid) 6+ years (Senior / Technical Lead)

We are looking for a hands-on Senior Engineer / Tech Lead to take significant technical ownership of our SaaS platform. The role combines architecture, implementation, code review, technical mentoring, and release ownership. This is not a management-only position. We expect the Tech Lead to remain deeply involved in the codebase and personally implement some of the most technically demanding areas of the platform. A major responsibility of this role is to establish an engineering system where developers can deliver consistently without every technical decision or code review depending on a single person.

Responsibilities

Provide technical leadership across backend and platform engineering
Review pull requests and maintain a high engineering quality bar
Guide engineers on architecture, implementation patterns, testing, and repository conventions
Own key backend services and shared platform capabilities
Design and review relational data models and database architecture
Ensure strong tenant and data isolation
Lead implementation of authentication, authorization, and policy enforcement
Design and maintain event-driven workflows and service integrations
Break specifications into clear, executable engineering tasks
Resolve difficult technical issues and implementation blockers
Contribute to architecture decisions and document significant decisions through concise architecture records
Improve engineering standards, CI pipelines, release processes, and production readiness
Mentor engineers through reviews and technical discussions
Work closely with Product, QA, and Design to convert product requirements into reliable releases
Remain hands-on and contribute directly to implementation

Requirements

6+ years of professional backend or full-stack engineering experience
Strong expertise in TypeScript
Deep practical knowledge of SQL, PostgreSQL, and relational data modelling
Experience designing production SaaS systems
Experience building or operating multi-tenant applications
Strong understanding of API design, application architecture, and data-access patterns
Experience with event-driven architecture, messaging, or technologies such as Kafka
Experience with caching and search technologies
Strong code-review capability and the ability to identify architectural and maintainability issues early
Previous experience acting as a Tech Lead, Senior Engineer, Staff-level contributor, or the most senior engineer within a team
Evidence of improving the effectiveness of other engineers through mentoring, documentation, review, and better engineering practices
Ability to make pragmatic architectural decisions in a small product company
Good judgment regarding what must be engineered thoroughly now and what can reasonably be deferred

Nice to Have

Experience with Hono, Bun, Kysely, or TanStack Start
Experience with policy-based authorization technologies such as Cerbos or OPA
Experience with Kafka, Redis, and OpenSearch
AWS architecture experience
Infrastructure-as-code experience using OpenTofu or Terraform
Experience with data-residency or regulatory requirements
Experience working on HR, payroll, accounting, financial, CRM, ERP, or other regulated business systems
SaaS product experience involving customers in India, the Middle East, or international markets
