Principal Full Stack Engineer (Enterprise SaaS)

We are seeking a  Principal Full Stack Developer / Engineering Lead  to define and drive the technical evolution of our platform, scaling it to support the next generation of our SaaS products. This is a  hands-on leadership role  at the intersection of architecture, system design, cloud infrastructure, and engineering leadership more about enabling and guiding teams than day-to-day feature delivery.

What Youll Do

Set the technical architecture  — design distributed systems, service boundaries, integration patterns, and data flows for scalability, performance, and resilience.

Lead design and architecture reviews , ensuring solutions align with long-term business and platform goals.

Guide senior engineers  in implementing backend services, APIs, and infrastructure with best practices and patterns.

Drive scalability strategy  — multi-region deployments, zero-downtime releases, resilience engineering, and disaster recovery.

Shape data strategy  — database selection, schema design, caching (Redis, CDN, edge compute), and event-driven architectures.

Ensure frontend excellence  through React / Next.js architecture, state management, and component design.

Advance DevOps maturity  — AWS infra automation, CI / CD pipelines, observability, and reliability engineering.

Elevate engineering standards  — performance-first, secure-by-default, design-for-failure principles.

What We’re Looking For

12+ years of experience  in software engineering, with several years as a Principal, Staff, or Lead Engineer.

Proven experience at scale  — architected or migrated event-driven, cloud-native SaaS applications, de-risked initiatives with Kubernetes, containers, serverless, and microservices.

Talent development  — hired and scaled distributed engineering teams, built processes for productivity, and codified engineering principles.

Strong product & design sense  — able to thrive in ambiguity, lead tech discoveries, manage tech debt, and deliver 01 products.

Hands-on developer  — contribute actively to backend (Node.js / TypeScript, Rails) and frontend (React / Next.js / React Native).

DevOps & Analytics expertise  — infra scaling, CDP, leveraging data for product conversion optimization.

Performance optimization  — query tuning, caching strategies, reducing latency in high-throughput systems.

Innovation at scale  — proven success integrating AI into both developer lifecycle and customer-facing products.

Current & Evolving Tech Stack

Backend :  Node.js / TypeScript (evolving), Python, ServiceNow

Frontend :  Next.js, React, React Native

Cloud & Infra :  AWS (ECS, S3, CloudWatch), Docker, GitHub Actions

Databases :  PostgreSQL, Redis

Other :  REST APIs, OpenAPI, Feature Flags, Advanced monitoring (Sentry)

You’ll have the freedom to  evaluate and evolve our stack , introduce new frameworks and patterns, and set architectural guidelines that outlast individual technologies.
