About Antithesis We've been quietly reinventing how the world thinks about software reliability, and we're just getting started! At Antithesis, we start at the foundations - we run entire software systems inside a deterministic simulation and break them in every way imaginable. Every issue then comes with a perfect reproduction, so you can identify root causes fast instead of spending days trying to recreate what went wrong. The rise of AI-generated code has made this work more urgent than ever. Agents can write code faster than any human, but speed doesn't matter much when the output is buggy, stuck in review, or slipping through undetected. The verification bottleneck is real, it's growing, and solving it is one of the most consequential problems in software right now. That's what you'd be working on. We're well-funded and deeply technical, the kind of place where the hardest problems get the most attention and the best ideas win regardless of who has them. If you want to do work that actually moves the needle on how reliable software can be, keep reading. About This Role Antithesis is looking for an IT Engineer to drive and evolve our IT infrastructure as we scale in the UK. You'll be the person our engineers rely on to keep their environments running, their access managed, and their issues resolved quickly. This role sits at the intersection of endpoint management, network infrastructure, and internal tooling, and you'll have real ownership over the systems and processes you build. Day to day, you'll manage our Mac and Linux fleet using Mosyle and Apple Business Manager, support our network and VPN infrastructure, and serve as our primary escalation point for endpoint and application issues. You'll also help build the documentation and operational foundations that let us move fast without losing institutional knowledge. This is a hands-on role for someone who likes solving technical problems, working across teams, and building things that last. If you thrive in fast-moving environments and want to have a meaningful impact on how a rapidly growing engineering company operates, we'd love to talk. What You'll Do Manage and support our technology using tools like Mosyle and Apple Business Manager, keeping hardware and software environments running smoothly across the company. Maintain network infrastructure including VPNs, DNS, firewalls, and wireless systems, collaborating with engineering and other teams to keep things reliable and secure. Serve as Tier 1 and Tier 2 support for endpoint, network, and application issues, tracking and resolving problems through Linear with a focus on fast resolution. Own asset management and security compliance, maintaining accurate records in our corporate asset database and ensuring we're meeting relevant compliance frameworks. Build and maintain documentation on IT processes, configurations, and architecture so knowledge is shared and the team can scale without losing institutional context. What We're Looking For Hands-on experience in IT systems administration or a similar role, ideally in a fast-paced or high-growth tech environment. Strong working knowledge of macOS and Linux (Ubuntu or similar), with familiarity with NixOS and modern endpoint management tools. Experience with identity and access management platforms like Google Workspace, Okta, or Azure AD. Solid networking fundamentals, including DNS, DHCP, firewalls, VLANs, and wireless infrastructure. Clear communicator who documents well, troubleshoots methodically, and takes ownership of problems through to resolution. Nice to Haves: Experience working in a dynamic start-up environment working with complex systems Global experience supporting team members in other countries including the US & Asia

Right now, who gets funded depends on who you happen to know. If you're in Silicon Valley with the right warm intros, you raise. If you're a brilliant founder in Lagos, Karachi, Bogotá or anywhere outside the default networks, you spend months in cold email purgatory, regardless of how good your company or non-profit is. IRIS is rebuilding that. She's a personal AI fundraising agent for the most exceptional founders. She gets to know each founder, their stage and what they're raising, then makes the warm introductions that move their round forward. IRIS works both sides of that connection. For investors, she's signal: a stream of qualified, pre-vetted founders matched to their real thesis, with the warm path already mapped, and far less noise than their inbox. The founders get access; the investors get the right founders in front of them. Underneath, IRIS is a relationship intelligence layer, part network operating system, part CRM, part autonomous agent, that learns from every interaction and gets sharper the more the network uses her. She lives where founders and investors already work, across email, WhatsApp, phone and web. We're starting with women founders in Europe, and building toward every founder, in every market, who has been raising on the wrong side of the network. We're looking for a Founding CTO to lead the technical build of IRIS, shape product and architecture from day one, and grow the engineering team as the company scales. Tasks Translate real-world network behaviour into structured data and intelligent, AI-driven workflows Own the product architecture from MVP to scale across email, WhatsApp, phone and web, on a secure, serverless cloud foundation Design AI systems with a strong focus on safety, fairness, privacy and transparency, ensuring recommendations and matching logic are responsible, explainable and free from harmful bias. Implement best practices for AI governance, model evaluation and responsible data usage as the platform scales Understand user requirements and work with the CEO to build the technical strategy and roadmap Be hands on and build and lead the engineering team as the company grows Requirements Strong AI engineering background, with hands-on experience building and scaling AI or data-driven products in production Experience building trustworthy AI products, including model evaluation, bias mitigation, privacy-preserving systems and safe deployment practices Deep technical familiarity with modern cloud and serverless infrastructure Ability to move fast from zero to one with limited resources Product-minded engineer who understands user behaviour and real-world workflows (you prioritise frictionless data capture over clunky UI layers) Comfortable with ambiguity and shaping technical directionExperience in the venture ecosystem is a strong advantage Willing to work close to European hours Benefits Build a product that meaningfully changes who gets funded Shape a new category of AI product, one that lives where people already work and acts on their behalf, not behind another chat window Founding equity, high ownership, real impact Work directly with a founder who has built and raised VC capital before (Cellcraft, Series A in progress) Shape the technical and ethical foundations of the product from day one The way capital gets allocated today is inefficient and unfair. The best founders don't always get funded; the best-connected ones do. That's a routing failure, and it has real consequences for which companies get built and which problems get solved. IRIS is an attempt to fix it at the infrastructure level. We're opening access to networks that were closed, routing capital toward fit and merit rather than proximity, and moving founders forward with the coaching and preparation they need to actually succeed once they get the meeting. Done right, this changes who gets funded, and that changes what gets built.
