UK Market • Multi-layered Smart analysis • Updated April 2026
TypeScript (Advanced/Production-Level) — 45% demand vs 28% supply (17-point gap)
While many developers list TypeScript on their CV, employers report that genuinely proficient TypeScript developers — comfortable with advanced generics, type narrowing, and large-scale type-safe architectures — are harder to find than the headline numbers suggest.
AI/LLM Integration — 22% demand vs 9% supply (13-point gap)
Employers want developers who can integrate LLM APIs, build RAG pipelines, and embed AI features into products. The skill is so new that supply lags well behind demand, and formal training pathways are still maturing. Developers who can demonstrate practical AI integration projects command a premium.
Security-Aware Development (DevSecOps) — 25% demand vs 12% supply (13-point gap)
Regulatory pressure (UK GDPR, FCA requirements) and rising cyber threats mean employers want developers who understand OWASP, secure coding practices, and dependency scanning. Most developers have limited formal security training, leaving a persistent gap.
Infrastructure as Code (Terraform/Pulumi) — 18% demand vs 6% supply (12-point gap)
As organisations shift deployment responsibility left to developers, IaC skills are increasingly requested in software developer roles. However, most developers have not been trained in infrastructure tooling, creating a significant gap. Candidates with this skill can differentiate themselves strongly.
Observability & Monitoring (OpenTelemetry, Datadog, Grafana) — 20% demand vs 10% supply (10-point gap)
With the shift to distributed microservices, employers expect developers to instrument their own code for observability. Most developers have relied on ops teams for monitoring, so hands-on experience with tracing, structured logging, and dashboarding remains scarce at the developer level.

The largest is TypeScript (Advanced/Production-Level) with 45% employer demand but only 28% of professionals listing it. While many developers list TypeScript on their CV, employers report that genuinely proficient TypeScript developers — comfortable with advanced generics, type narrowing, and large-scale type-safe architectures — are harder to find than the headline numbers suggest.
Emerging skills for Software Developer roles include AI/LLM Integration (e.g. OpenAI APIs, Copilot), Infrastructure as Code (Terraform/Pulumi), Rust, Platform Engineering / Developer Experience, AI-Assisted Development (GitHub Copilot, Cursor). These are increasingly appearing in job postings and represent future demand.
