Lead Software Engineer - Fitpage & India Running

Mumbai (On-site) • 6–9 years • Engineering / Product Technology • Full-time

About Us

Fitpage and India Running are part of Saransh Ventures Pvt. Ltd., a fast-growing platform at the

intersection of fitness, wellness, and running culture in India. Fitpage builds content, training, and

nutrition programs that help people improve their cardiovascular fitness, while India Running operates

the country’s largest marketplace for running events — powering registrations and a full suite of services

for event organisers nationwide.

Alongside a portfolio of brands and events — including Wesness, Ascend, Captured, and partnerships with

global names like New Balance — we ship consumer products used by a fast-growing community of

runners and fitness enthusiasts. We’re a lean, fast-moving team where engineers own what they build

and see its impact directly.

The Role

We’re looking for a Lead Software Engineer to set the technical bar across Fitpage and India Running. This

is a hands-on technical leadership role: you’ll own the architecture and quality of major parts of our web

and backend platform, lead the design and delivery of complex features end-to-end, and multiply the

team through mentorship, design reviews, and rigorous code review.

You’ll stay one of the strongest builders in the room. This role leads through technical depth and influence

rather than headcount — working shoulder-to-shoulder with the Engineering Manager, product, design,

and founders to ship fast without compromising on quality.

What You’ll Do

• Own the architecture and technical direction for major product areas across Fitpage and India

Running, spanning React/Next.js front-ends and Nest.js/Node.js services.

• Lead the design and delivery of complex, high-performance features end-to-end — from data model

to API to responsive UI, using SSR/SSG where it counts.

• Make and document the hard architectural calls: service boundaries, data modelling, API contracts,

and scalability and cost-performance trade-offs on AWS.

• Set and enforce engineering standards — code quality, testing, security, performance, and

observability — and hold the bar through design and code review.

• Act as technical lead on cross-functional initiatives, turning ambiguous requirements into clear,

sequenced, shippable milestones with product and design.

• Design secure, scalable APIs and robust authentication/authorization (JWT/OAuth2) across services.

• Own reliability and maintainability: testing strategy, CI/CD, incident response, and keeping technical

debt in check as we scale.

• Grow the engineers around you through mentorship, pairing, and technical feedback — and help raise

the team’s bar through technical interviews and hiring.

What We’re Looking For

• 6–9 years of software engineering experience, with a strong track record of building and shipping full-

stack products.

• Deep, hands-on expertise across the stack: JavaScript and TypeScript, React and Next.js (SSR/SSG),

and Node.js/Nest.js.

• Strong relational data modelling and query optimisation in Postgres — schema design, indexing, and

performance; working knowledge of MongoDB.

• Proven experience designing scalable, secure APIs and implementing authentication/authorization

(JWT/OAuth2).

• Solid working knowledge of AWS — deployment, infrastructure, and cost-performance trade-offs.

• A track record of owning architecture for a product or domain and leading other engineers through

design and code review.

• The judgment to balance technical depth with delivery speed in a fast-paced, resource-constrained

startup environment.

• Excellent communication — comfortable working directly with founders, product, design, and non-

technical stakeholders.

• A bias for owning outcomes, not just output.

Good to Have

• Experience with microservices or serverless architectures.

• Familiarity with Docker, Kubernetes, and Terraform.

• Exposure to cross-platform mobile development with Flutter — our platform spans web and mobile.

• Experience in consumer apps, fitness/wellness, or community-led products.

• Contributions to open-source projects or meaningful personal side projects.

What You’ll Get

• High ownership and autonomy — your technical decisions directly shape the product.

• Direct access to founders and leadership.

• The chance to set the engineering bar and shape technical culture as we scale.

• Work on products used by a fast-growing community of runners and fitness enthusiasts across India.
