A Full Stack Developer builds and maintains both the user-facing and server-side components of web applications, typically working across a JavaScript or TypeScript stack with React on the frontend and Node.js or a similar runtime on the backend. The day-to-day blends feature work — translating Figma designs into accessible UI components, wiring up API endpoints, modelling data in PostgreSQL or MongoDB — with the less glamorous reality of debugging production issues, reviewing pull requests, and refining CI pipelines. Most sit within a product squad of five to eight people alongside a product manager, designer and one or two other engineers, reporting into an Engineering Manager or Tech Lead. Unlike specialised frontend or backend engineers, Full Stack Developers are valued for their ability to own a feature end-to-end without handoffs, which makes them particularly common at startups, scale-ups, and agencies where headcount efficiency matters. Expect ticket refinement, sprint ceremonies, on-call rotations at larger companies, and a fair amount of stakeholder conversation about scope and trade-offs. Increasingly, the role also includes lightweight DevOps responsibilities — deploying to AWS, managing environment variables, monitoring with Datadog or Sentry — and, in 2024-2025, integrating LLM-powered features into existing products.
TypeScript at depth — 68% demand vs 40% supply (28-point gap)
Many developers list TypeScript on their CV but use it as 'JavaScript with annotations'. Genuine type system fluency (generics, conditional types) is rarer than postings suggest.
Cloud Infrastructure (AWS/Azure) — 55% demand vs 32% supply (23-point gap)
Full stack roles increasingly expect IaC and deployment ownership, but many candidates have only worked behind a DevOps wall and lack hands-on cloud experience.
System Design for Web — 50% demand vs 28% supply (22-point gap)
Beyond mid-level, employers expect candidates to reason about caching, queues, and data modelling. Many self-taught and bootcamp-trained candidates have feature-building skills but limited architectural exposure.
AI/LLM Integration — 28% demand vs 8% supply (20-point gap)
Demand is exploding as every product team wants AI features, but most developers haven't yet shipped production LLM integrations. Candidates with even one or two real projects stand out significantly.
Where the Full Stack Developer role sits relative to nearby roles in the market — what genuinely distinguishes it.
How people enter this role: Most enter via a Computer Science degree followed by a graduate scheme, a coding bootcamp with a junior role, or self-taught conversion from an adjacent technical field. A growing minority arrive via apprenticeships. Two to three years of focused web development experience is typical before earning the 'Full Stack' label outright.
Typical progression: Junior Full Stack Developer → Full Stack Developer → Senior Full Stack Developer → Tech Lead → Engineering Manager or Principal Engineer
Typical tenure in role: ~24 months
Common lateral moves: Frontend Developer, Backend Developer, Product Engineer, Solutions Engineer
