Find Backend Developers

About the profession

Backend developers own the data model, the APIs and everything that has to stay correct while under load. The visible surface is small; the cost of getting it wrong is not. Schema design, transactions, background jobs and failure handling are where the real work sits.

Language is a weaker filter than domain. Someone who has run a payments system or a high-write ingestion pipeline brings judgement that transfers across stacks more readily than syntax does.

Skills to look for

• Node.js, Python, Go, Java, PHP or .NET
• Relational database and schema design
• SQL performance and indexing
• REST and GraphQL API design
• Caching and queues
• Authentication, authorisation and security
• Docker and CI/CD
• Observability, logging and alerting

Common specialties

Payments and billing

Idempotency, reconciliation and provider webhooks.

Data pipelines

Ingestion, transformation and scheduled processing at volume.

APIs and integrations

Public APIs, third-party integrations and versioning.

Real-time systems

Websockets, streaming and event-driven architecture.

Security and compliance

Access control, auditability and data-protection requirements.

Experience and seniority

Junior developers implement defined endpoints and tests. Mid-level developers design a service and its data model. Senior developers make the calls that are expensive to reverse — schema, boundaries, consistency guarantees — and handle production incidents.

Remote, hybrid or on-site

Remote-first for most teams. On-site requirements usually come from regulated environments, on-premise infrastructure or hardware-adjacent work.

How unigrig matching works for this role

Tell unigrig about the system, not just the language: traffic, data sensitivity, existing infrastructure. Matching uses each professional's stated skills, seniority and industry background so domain experience surfaces properly.
