Job description

Location : Remote (India)

Compensation : ₹50L–₹80L per annum (depending on relevant experience)

Company : [FileSpin.io] – AI-powered Digital Media Management Platform

About Us

FileSpin.io is a fast-growing B2B SaaS platform providing AI-powered Digital Asset Management (DAM) and Media Processing . We help enterprises scale their content operations with features like background removal, face recognition, video / image transformations, CDN delivery, and workflow automation.

We're looking for a hands-on Senior Developer / Technical Lead who can take technical ownership, lead execution, and grow into our Chief Technology Officer over the next 12–24 months.

This is a unique opportunity for someone who wants to take on and shape a product that is scaling globally.

We can’t match the salaries offered by large corporations but we offer something far more valuable — ownership and influence. At FileSpin.io, you’ll have the freedom to shape our technology, make real decisions, and see your work directly impact the direction of the company.

Role Overview

You’ll start as a Technical Lead , hands-on with backend architecture, APIs, and performance optimisation — and gradually take ownership of :

Technology roadmap & architecture
Infrastructure & scaling decisions
Team growth and mentoring
R&D direction for AI / ML features
Process improvement and automation

This is a rare opportunity for an ambitious engineer who wants to evolve into a CTO role within a fast-growing SaaS company.

As our Technical Lead , you will :

Take technical ownership of our core SaaS platform (Python, MySQL, Celery, OpenSearch, Redis, React frontend).

Train and Deploy ML models at scale

Make architectural and design decisions that impact scalability, performance, and reliability.

Lead and mentor a small team of developers; instill best practices in coding, testing, and deployment.

Drive DevOps & infrastructure choices (AWS, Docker, GPU servers for ML inference, Github.).

Partner with the founder (current acting CTO) and step into leadership of technical roadmap planning and R&D.

Collaborate with product, sales, and customers to deliver features that create clear business value.

Champion security, compliance, and reliability across the platform.

Our Tech Stack

Backend : Python, FastAPI, Celery, REST APIs

Data & Search : MySQL, OpenSearch, Redis / Valkey

Frontend / Design : React, Next.js, Tailwind, Framer Motion, Figma

Infrastructure : Docker Swarm, AWS S3, Cloudflare R2, n8n

ML / AI : NVIDIA GPUs, Triton inference server, custom models

Workflows : Celery distributed tasks

Technical Requirements

8+ years experience in software engineering with a track record of shipping SaaS products.

Strong expertise in Python, distributed systems, and cloud-native architectures.

Deep experience in databases, caching, queues, and search at scale.

Comfort with AWS services, Docker Swarm, Kubernetes, and CI / CD pipelines.

Experience with machine learning pipelines, GPU inference

Experience with Image / Video processing at scale is a plus

Leadership & Soft Skills

Clear communicator and a strong sense of ownership

Able to work with Startup Hustle — thrives in a fast-moving environment that values delivery speed, ambiguity, teamwork, and multi-hat ownership.

Experience (or interest) in mentoring and technical decision-making

Eager to learn business context and drive outcomes, not just code

Ambition to grow into a CTO role within 12–18 months

What Success Looks Like

Within 3 months : Owns key modules, delivers high-quality code, and improves system performance

Within 6–9 months : Independently leads product / feature releases

Within 12–18 months : Oversees all technical decisions, engineering operations, oversee enterprise customer infrastructure

Why Join Us

Impact & Ownership : Directly influence the technical direction of a growing SaaS platform.

Growth Path : Opportunity to step into the CTO role as we scale.

Cutting-edge tech : Work with AI / ML, distributed systems, and media processing at scale.

Global customers : Our clients include enterprises in events, e-commerce, media, and more.

Flexible work : Remote-first culture, outcome-driven, not time-clock driven.

Compensation : Competitive salary + performance bonus

Culture of learning, trust, and technical excellence
