Meet Aperture Aperture is a growth consultancy and advertising partner for some of the world's most ambitious ecommerce brands. We plan, build, and manage performance marketing programmes across Meta, TikTok, Google, and beyond — with a strong focus on creative strategy and paid social. We work across performance marketing, creative strategy, and now, increasingly, proprietary tooling that gives us and our clients an edge. Founded in 2022 and based across London, we work with clients across the US and Europe. We're a small, senior team that moves fast, thinks carefully, and holds ourselves to a high standard. Our job is to make growth happen. Our culture Client success is our success. Period. We're direct. We say what we mean and we mean what we say. We do the work. No one here is above anything. We hire people we trust and we trust the people we hire. We move fast, but we don't cut corners where it matters. We operate with high standards and low ego. We're here to build something good, not just something big. We back our people when it counts. The role Aperture OS is an internal tool we've built to give us an operational edge. It helps us track performance, manage creative workflows, and surface insights across our client portfolio in ways that off-the-shelf tools don't. Now we want to scale it. We're looking for someone to own it. Not manage it. Own it. You will be the primary engineer and technical decision-maker for Aperture OS. You'll define what it becomes, how it's built, and how it serves the team. You'll work directly with the founder and client teams to understand what's needed and build it — properly. This is a serious ownership opportunity at a fast-moving company that knows what it wants and gives its people room to deliver it. What you'll own The full Aperture OS codebase — architecture, quality, and evolution. Feature development end-to-end: scoping, building, shipping, iterating. API integrations — pulling data from ad platforms, creative tools, and internal systems. AI and LLM integrations — we use AI heavily in our creative and analysis workflows. Database design and data modelling as the product grows. Infrastructure, hosting, and deployment — keeping things running reliably. Security, access control, and compliance for a multi-client environment. Who this is for This is for a serious engineer who also builds. You don't wait to be told what to do — you figure it out, propose it, and do it. You're comfortable with ambiguity and you thrive in environments where the spec isn't always written in advance. You can move quickly when speed is needed and slow down when precision matters. You care about the product you're building, not just the code. You think about the person using it, the problem it solves, and whether it's actually good. You've probably worked in a startup or early-stage environment before. You know how to operate without a lot of support infrastructure. You use AI tools in your daily workflow — not as a crutch, but as a force multiplier. You know when to trust them and when to check the output. You might have a background in performance marketing, growth, or adtech — or you might not, but you're genuinely curious about it. If something breaks at 2am and it's your product, you feel it. That's the kind of ownership we're looking for. How we work Aperture is remote-first and impact-first. You can work from wherever you are most productive. We care about the output, not the hours. We do occasional team meetups and we'll bring you in when it makes sense. You'll have direct access to the founder and the team. No layers, no slow approvals, no bureaucracy. Requirements Proven track record shipping with AI-first development tools: Lovable, Cursor, or similar. Experience owning a full codebase, not just contributing to one. Strong command of TypeScript and React on the frontend; and serverless/edge functions for backend logic. Good working knowledge of Supabase for authentication and database (Postgres). Experience integrating third-party APIs, especially AI and LLM APIs. Solid working knowledge of DNS, domain management, SSL/TLS, and hosting configuration. Experience scaling systems in a multi-tenant SaaS environment, with asynchronous processing such as worker fleets, pub/sub, queues and streams. A sensible approach to testing: you know what needs a test and what doesn't. You think about security and data compliance as you build, not as an afterthought. Strong product instincts: you know the difference between something that works and something that is right. Ability to set priorities and make tradeoffs without constant direction. Familiarity with performance marketing, ad creative testing, or growth tooling. Benefits Work from anywhere, with flexibility around how you structure your day. Regular team meetups and events. Travel to team meetups covered. Direct exposure to a fast-growing business and its founder. Real ownership of a product people use every day. A high-trust role with responsibility from day one.
