Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Member of Technical Staff - Engineering Lead, Applications - **Company:** Reflection - **Location:** London, UK - **Experience:** Expert - **Contract:** Permanent contract - **Skills:** Admin Tools, Application Programming Interfaces (APIs), Software Architecture, Role-Based Access Control, Systems Integration, TypeScript, ReactJS, Fastapi - **Published:** July 17, 2026 - **Apply:** https://uk.indeed.com/viewjob?jk=626958b63c5f5bd5 ## About the Role * Experience building, mentoring, and growing engineering teams while staying technically hands-on. (Comfortable growing into leading a team of ~10 quickly if you haven't managed at that scale before.) * Deep full-stack engineering experience, with real ownership of production-grade applications shipped end to end. * Strong coding ability and the credibility to earn the technical trust of a strong team. * Comfortable across the full delivery surface - UI through API through auth - with depth in at least one layer and the ability to work across the rest. * Experience integrating with external systems or customer environments and making those integrations reliable and maintainable. * Ability to guide strategy and drive execution in a fast-moving, zero-to-one environment, and to partner effectively across research, platform, and product. ## Description Reflection's Applications team builds the product surfaces that turn raw platform capabilities into usable workflows - the internal dashboards, admin tools, and self-serve experiences our teams run on, and the customer-facing surfaces that connect Reflection to the outside world. This work sits at the intersection of engineering and product: translating ambiguous requirements into clean, operable systems and taking ideas from prototype to hardened production. As Applications Lead, you'll provide front-line leadership of the team that builds these surfaces. You'll build, mentor, and grow a team of full-stack engineers, guide the technical and architectural decisions that shape what we ship, and work closely with research, platform, and product to decide what gets built and how. You'll stay close enough to the stack - UI through API through auth - to make targeted contributions as an individual contributor and to maintain a deep understanding of the team's technical work., * Build, mentor, and grow a high-performing team of full-stack engineers. Coach and support your reports in understanding, and pursuing, their professional growth. * Provide front-line leadership of engineering efforts to build internal and customer-facing product surfaces dashboards, admin tools, and self-serve workflows. * Stay hands-on: become familiar with the team's technical stack enough to make targeted contributions as an individual contributor. * Manage day-to-day execution: prioritize the team's work and manage projects in a highly dynamic, fast-paced environment. * Guide technical and architectural decisions, emphasizing scalability, robustness, and user experience across React/TypeScript front ends, REST/gRPC APIs, Go/FastAPI services, and the auth, RBAC, and audit underneath. * Work closely with research, platform, and product to translate needs into clear system designs and usable interfaces, and to make integrations with customer environments reliable and maintainable. * Raise the bar for technical judgment, prioritization, communication, and execution in a fast-moving environment. ## Related Videos - [Build and Deploy a Fullstack App with Open Source Tooling](https://www.wearedevelopers.com/videos/775-build-and-deploy-a-fullstack-app-with-open-source-tooling) - [Intro to FastAPI](https://www.wearedevelopers.com/videos/462-intro-to-fastapi) - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [Do TypeScript without TypeScript](https://www.wearedevelopers.com/videos/327-do-typescript-without-typescript) - [Building and Deploying Multi-Agent Systems with ADK and Vertex AI](https://www.wearedevelopers.com/videos/1918-building-and-deploying-multi-agent-systems-with-adk-and-vertex-ai) - [Vuejs and TypeScript- Working Together like Peanut Butter and Jelly](https://www.wearedevelopers.com/videos/127-vuejs-and-typescript-working-together-like-peanut-butter-and-jelly) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [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) - [The Best X (Twitter) Accounts for Developers](https://www.wearedevelopers.com/magazine/294-the-best-x-twitter-accounts-for-developers) - [The Best Software Developer Blogs to Read](https://www.wearedevelopers.com/magazine/156-the-best-software-developer-blogs-to-read)
