Oneiros is an engineering company that designs, builds, and operates production-grade software systems for the world's most ambitious enterprises.
Founded in 2016 by systems architects who believed enterprise software could be beautiful, performant, and secure — without compromise. Today, our platforms serve millions across six continents.
A decade of relentless focus on one thing: building software that enterprises bet their business on.
Founded in a London co-working space by three systems architects who left Big Tech to prove enterprise software doesn't have to be ugly, slow, or insecure. First client: a seed-stage FinTech needing a real-time payments engine.
Signed our first Fortune 500 engagement — modernising a 20-year-old ERP monolith into cloud-native microservices. Delivered 6 months ahead of schedule. The client's CTO called it 'the fastest transformation I've witnessed in 25 years.'
Expanded the engineering team and built the internal platform engineering group that now powers our accelerated delivery model. Deepened enterprise client partnerships.
Launched the Oneiros AI practice — investing heavily in LLM engineering, MLOps, and responsible AI. Built our first AI-powered code migration tooling that now accelerates every modernisation engagement.
Launched the Oneiros product suite — Onei Service, Onei Supply, Onei Commerce, and Onei Identity. Shifted from pure consulting to a hybrid product + engineering model serving 200+ enterprise clients.
Growing engineering team based in Chennai. $2.1B+ in client revenue impacted. Expanding into quantum-readiness consulting, autonomous systems, and sustainability engineering. The best is still ahead.
Behind every number is a team that refused to ship anything less than excellent.
These aren't motivational posters. They're the operating principles embedded in every code review, sprint retro, and architecture decision.
We don't chase buzzwords. Every technology choice is justified by a written Architecture Decision Record, peer-reviewed by principal engineers. If it doesn't solve a real problem, it doesn't ship.
Open Slack channels, shared dashboards, weekly demos, and no black boxes. Our clients see everything — burn rates, velocity, blockers, and trade-offs. Trust is built on visibility.
CI/CD from day one, automated testing at every layer, and infrastructure-as-code as a non-negotiable. Speed without quality is just recklessness.
Every engagement includes structured knowledge transfer. We pair with your engineers, run workshops, and leave runbooks. When we exit, your team owns and operates everything.
We measure and minimise the carbon footprint of the systems we build. FinOps, right-sizing, serverless-first — sustainable engineering is just good engineering.
Our best architectures come from diverse perspectives. 42% of our engineers identify as women or non-binary. We actively recruit from non-traditional backgrounds because talent is everywhere.
We invest heavily in tooling, training, and developer experience. Our engineers choose the best tool for the job — not the one we already own.
We built the company we always wanted to work at — obsessively technical, radically transparent, and genuinely human.
Work from anywhere in the world. Our Chennai office is open for collaboration, but your desk is wherever you do your best work.
Conferences, courses, certifications, books — invest in yourself. We cover KubeCon, re:Invent, NeurIPS, and more.
One day a week to explore, prototype, and contribute to open-source. Some of our best internal tools started as Friday experiments.
Unlimited therapy sessions, mental health days, and a culture that genuinely respects work-life boundaries. No weekend Slack notifications.
Attend top conferences worldwide — from KubeCon to NeurIPS. Broaden your perspective, build your network, and bring fresh ideas back to the team.
IC and management tracks with published rubrics. Know exactly what's expected at every level. No guessing, no politics, just growth.
Whether you want to join our team, partner on a project, or just talk shop — we'd love to hear from you. The best conversations start with a simple hello.
We're always hiring exceptional engineers, designers, and domain experts. Remote-first, competitive comp, and the most interesting problems in enterprise tech.
