You've owned production systems end-to-end, designed APIs other people built on, and modelled data that held up as it scaled. Your track record shows systems that shipped, stuck, and stayed up. * Strong judgement under ambiguity. You balance speed, reliability, and cost, push back when something's underspecified, and make pragmatic calls when it needs to ship. * Systems taste. You notice when an interface is wrong, when a failure mode is unhandled, when something will hurt at 10x the load, and you say so. * Cross-functional pragmatism. You work effectively with founders, designers, and AI engineers. You unblock yourself rather than waiting. * AI literacy. You're fluent with modern coding tools (Claude Code, Cursor, agents, whatever you've settled on). You treat them as collaborators, know when to trust them and when to override them, and have opinions about where they help and where they get in the way. * Security sense. We serve banks and we're SOC 2 Type II certified. Auth, data handling, audit trails, and tenant isolation are things you think about by default. Strong technical depth in: * TypeScript specialist. You write it well and you've owned services end-to-end in it. * API design and data modelling. * Building production systems with AI in the critical path. * Postgres and Drizzle, or equivalent. * Modern web infrastructure. Node, distributed systems, the usual., * Python. * Cloudflare experience: Workers, Queues, and the wider Cloudflare stack. We run on it, so this is a real plus. * Experience with Hono or Drizzle. * Experience in regulated industries: fintech, healthtech, legaltech. ## Description This is a senior backend role at the core of the platform. You'll own the systems everything else runs on: the public API other companies build against, the integrations that reach into our customers' tools, and the infrastructure behind an AI pipeline that reviews real client data every day. You'll talk to the engineers and customers building on our API, and as a senior engineer you'll have real input into the architecture of the platform as a whole. What you'll do * Own our public-facing API. The contracts, the versioning, the docs, the auth. Other companies build on this every day, so the bar for it is high. * Build out our MCP server, the surface that lets AI agents act inside Adclear safely. * Build the integration layer that reaches into wherever customers create marketing: Canva, Figma, Google Docs, Contentful, and the rest. Handle the messy parts well: rate limits, auth quirks, the integration that breaks because someone else changed their API. * Help architect the infrastructure behind our AI pipeline. Orchestration, queuing, retries, latency, cost, and the eval system that runs against real client data daily. * Help keep the plumbing the whole team relies on in good shape: CI/CD in GitHub Actions, database migrations, monitoring and error tracking, alerting, and metrics. The systems you build should stay up, and tell us quickly when they don't. * Set the bar for backend engineering as we grow. We're six engineers today. What you build and how you build it shapes the team that comes after. * Ship a change to production on your first day and a feature in your first week. We deploy continuously. ## Related Videos - [Boost Productivity with AI: Figma & Playwright MCP Workflows - Aris Markogiannakis](https://www.wearedevelopers.com/videos/1768-boost-productivity-with-ai-figma-playwright-mcp-workflows-aris-markogiannakis) - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Shipping Faster with Less: Render on Cloud Hosting, AI Workloads, and the Future of DevOps](https://www.wearedevelopers.com/videos/1894-shipping-faster-with-less-render-on-cloud-hosting-ai-workloads-and-the-future-of-devops) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Designing the Future of Human<>Agent Collaboration](https://www.wearedevelopers.com/videos/1447-designing-the-future-of-human-agent-collaboration) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 159: AI Pipelines, 10x Faster TypeScript, How to Interview](https://www.wearedevelopers.com/magazine/563-dev-digest-159-ai-pipelines-10x-faster-typescript-how-to-interview) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [The Biggest German Tech Companies](https://www.wearedevelopers.com/magazine/424-the-biggest-german-tech-companies)
