Title : Senior Software Engineer (Fullstack)

Location : Mumbai, India

• Are you excited by the idea of helping scale a fast-growing tech business across London, Mumbai and Austin
• Do you want to contribute towards building cutting-edge automation systems that power real-time analytics and GenAI tools

We'd love to hear from you!

The Role

As a Senior Software Engineer, you'll build the products our customers rely on every day to make multi-million dollar media decisions. You'll work across the full stack - from crafting responsive, intuitive frontend experiences through to designing and scaling the backend microservices that power them - and, given the seniority of this role, you'll also help shape system design and infrastructure decisions as we scale. You'll work alongside engineers, product managers, and AI agents as part of our AI-first operating model, where lean, high-autonomy teams ship fast and learn faster. This is a hands-on engineering role for someone who's comfortable owning a feature end-to-end - from initial design through to production - and who wants to grow their craft in a fast-moving, ambitious environment.

Where you'll focus

• Frontend development using modern JavaScript frameworks (React.js or Next.js)
• Backend development using Python-based microservices
• System design and infrastructure, contributing to architectural decisions as we scale
• End-to-end feature ownership across the stack
• Nice-to-have: Exposure to Data Science / Data Engineering workflows

Key Responsibilities

• Design, build, and maintain full stack features - from frontend UI/UX through to backend services and APIs in Python.
• Contribute to system design and infrastructure decisions, helping evolve our technical foundations as we scale.
• Get involved across the full Software Development Lifecycle, from initial planning and design through execution, release, and monitoring in production.
• Write clean, well-tested, maintainable code, and champion good engineering practices across the team.
• Collaborate closely with product managers, designers, and fellow engineers to translate requirements into working software.
• Build and consume APIs (REST/GraphQL) that connect frontend experiences to backend services.
• Work with AI agents as part of our AI-first operating model, using clear specifications to shape high-quality, AI-assisted engineering work.
• Take ownership of the quality, performance, and reliability of the features you ship.
• Participate in code reviews, giving and receiving candid, constructive feedback.
• Stay curious about new tools and technologies, including opportunities to explore Data Science / Data Engineering problems as they arise.

You don't have to tick every box. If you're a strong engineer who's hungry to step up, we'd still like to hear from you.
