The ideal candidate enjoys creating scalable platforms, developer tooling, and best-practice frameworks that enable engineering teams to build., Essential - Strong application-development experience, enough real-world app-dev depth to define how applications should be built well, and to encode that as patterns and quick starts others rely on. This is the core of the role. - Strong AWS application development and software engineering experience, ideally on developer tooling, delivery platforms, or cloud-native developer workflows. - You already use AI daily for engineering work. You build with a coding harness/agent as a matter of course, and the more experience you have driving one, the closer to spec-driven development, the better. This is central to how we work, not a bonus. - Solid knowledge of AWS serverless and event-driven services: - Lambda - API Gateway - Step Functions - Integration patterns across AWS services - Experience automating CI/CD, SDLC, and engineering controls: - GitHub Actions - Infrastructure as Code - Automated evidence capture - Experience building automated governance, compliance, or operational controls into delivery pipelines, turning policy and regulatory requirements into code and evidence. - Comfortable implementing both: - Deterministic scripted checks - Agentic applications that reason over the problem - Financial services or regulated-industry experience is a plus. - Good engineering practice as second nature: - API design - Automated testing - Observability - Documentation - Secure-by-default delivery - Comfortable operating independently in a fast-moving programme and contributing from early on. Nice to have - Python/FastAPI for building production APIs and services. - TypeScript/React for web front ends and developer consoles. - Experience building internal developer platforms or "platform-as-a-product." - Experience building agentic applications, or designing APIs/CLIs and reusable skills for both human and agent consumers. - You don´t need to have built agentic apps, but experience working through a harness matters. What you´ll be like - A hands-on engineer with a builder´s mindset, happy close to the code, shipping practical capability. - Fluent with AI-assisted engineering. You reach for a harness by default and think in terms of specs and outcomes. - Opinionated about good application development, and able to turn that judgement into patterns others can follow. - Pragmatic and self-sufficient, able to make progress where priorities shift as the platform is proven with real users. - Product-minded and customer-focused, genuinely interested in making the paved road useful. - Security- and automation-conscious. You build controls and quality in, rather than leaning on manual process. - Clear and collaborative across platform, application, security, identity, and service-management stakeholders. ## Related Videos - [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) - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [Blueprints for Success: Steering a Global Data & AI Architecture](https://www.wearedevelopers.com/videos/1577-blueprints-for-success-steering-a-global-data-ai-architecture) - [Engineering Mindset in the Age of AI - Gunnar Grosch, AWS](https://www.wearedevelopers.com/videos/1735-engineering-mindset-in-the-age-of-ai-gunnar-grosch-aws) - [Bringing AI Model Testing and Prompt Management to Your Codebase with GitHub Models](https://www.wearedevelopers.com/videos/1536-bringing-ai-model-testing-and-prompt-management-to-your-codebase-with-github-models) - [Hiring AI Native Talents](https://www.wearedevelopers.com/videos/100268-hiring-ai-native-talents) ## Related Articles - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Find a Developer Job: 12 Best Job Sites For Developers](https://www.wearedevelopers.com/magazine/165-find-a-developer-job-12-best-job-sites-for-developers) - [What is Software Engineering in the Age of AI?](https://www.wearedevelopers.com/magazine/640-what-is-software-engineering-in-the-age-of-ai) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated)
