• providing hands-on technical leadership and helping establish engineering patterns, standards, and best practices,
• translating product requirements and emerging ideas into pragmatic, scalable technical solutions,
• working across frontend and backend, with a strong focus on TypeScript, JavaScript, React, and Node.js or Deno,
• designing and integrating REST APIs, webhooks, event-driven integrations, and third-party SaaS platforms,
• contributing to technical decisions around authentication, authorisation, data access, security, performance, and reliability,
• mentoring engineers, sharing knowledge, and helping raise engineering capability across the team,
• collaborating with Product, Architecture, Platform Engineering, and other engineering teams,
• experimenting with emerging technologies and turning successful prototypes into production-quality solutions,
• supporting modern CI/CD, testing, observability, and production engineering practices.

Requirements

• 10+ years of professional software engineering experience, ideally across modern full-stack web applications and enterprise products,
• strong hands-on expertise in TypeScript and JavaScript, with significant production experience in React and backend runtimes such as Node.js or Deno,

• excellent problem-solving and debugging skills, particularly across complex full-stack and third-party integration scenarios,
• strong communication and collaboration skills, with the ability to work effectively across engineering, product, architecture, and platform teams,
• automation-first and product-focused mindset, comfortable working with emerging technologies while maintaining the engineering discipline required to operate software at enterprise scale,
• Work from the European Union region and a work permit are required.

Preferred

• experience using LLM APIs, AI SDKs, or developing AI-enabled applications,
• familiarity with the Vercel ecosystem, TanStack Query, React Router, Tailwind CSS, or shadcn/Radix,
• experience working with developer platforms such as GitHub or Jira.
• experience applying GenAI in a more structured way within the SDLC, including defined workflows, prompt patterns, or tool integrations embedded into daily work,
• interest in and familiarity with emerging AI-driven practices (e.g. agent-based workflows, automation patterns, AI-augmented development), with a willingness to explore and experiment beyond standard approaches.
