Role Overview
As a Full Stack Engineer at Index, you will work across the frontend, backend, and platform layers.

What We Offer
About Us
Index is a UK-based company providing end-to-end remote-work services, powered by our digital platform. We help leading companies like GoEuro, Vodafone, Venly, YC startups, and 100 more companies to scale their engineering team by finding and managing high-performing tech talent.
The company was founded 2019 and headquartered in London. We unite top engineering talent from around the world and connect them with innovative companies seeking high-performing teams.
It was co-founded by an Oxford alumnus and tech executive with a track record of building successful global teams and scaling output rapidly.
Why Join Index.dev
We are officially recognized by the Financial Times as one of Europe’s fastest-growing companies: in 2024 we ranked 29th overall and 6th in IT & Software among the FT 1000.
We scale faster than market average — enabling us to offer frequent, meaningful opportunities for those who perform.
From Talent Marketplace to Full-Service Software Powerhouse
In October 2025 we completed the acquisition of Codemotion — a seasoned, U.S.-based custom software development company with a 60+ strong engineering team, decades of enterprise-project experience, and clients such as NASA, Neom, and MongoDB.
This strategic move transforms us from a talent-matching platform into a full-fledged software delivery partner: end-to-end solutions, from MVP to production, including CTO-level leadership, project management, design, QA, and scalable engineering teams.
As a result — along with helping hire developers, we’re delivering entire products and complex systems. We now serve clients in 180+ countries, offering broad timezone overlap, flexible staffing models, and a diversity of technical skills and cultural backgrounds.
Our growth trajectory ensures that high-performers don’t just onboard — they accelerate. With access to enterprise-level clients, cross-functional teams, and varied domains (FinTech, Blockchain, Healthcare, AI), talent can grow in ways rarely possible in traditional setups.
Our Vision & Mission: Where We’re Going Next
We are growing fast and have the vision of building the leading software development company in the world.
We believe that remote-first, globally distributed engineering teams are the future.
Our Goals Include
If you’re motivated by scale, impact, complex projects, and global collaboration, Index.dev is the kind of place where your efforts will be amplified.
