What great Backend Developers look like

Strong backend developers design APIs others enjoy using, model data carefully, think about failure and concurrency, and treat security as part of every feature. They profile before optimising, write tests that describe business rules and make systems observable so problems are diagnosed quickly.

Questions we ask in technical interviews

• How would you design an idempotent payment endpoint?
• How do you choose between SQL and NoSQL for a feature?
• How do you handle schema migrations on a live database?
• How do you trace a slow request in production?

Typical projects for Backend Developers

• APIs for web and mobile apps
• Third-party integrations
• Performance and scalability work
• Background processing and queues

The first 30 days with a new back-end developer

Every engagement starts with a short, structured onboarding so you see useful output early and can judge fit quickly. A typical first month looks like this:

1. Week 1 — Orientation

   Runs services locally, reads the data model and API docs, reviews logging and alerting, and fixes a small bug.

2. Week 2 — First endpoint

   Delivers a new endpoint or job with validation, tests, migrations and documentation.

3. Week 3 — Observability

   Reviews slow queries and error logs, adds missing indexes or metrics, and reports findings.

4. Week 4 — Ownership

   Takes a feature across the API, data layer and integrations, including on-call handover notes.

What to look for beyond the CV

Years of experience and a list of technologies say little about how someone works. In our screening and in your interviews, these are the signals that matter most:

• Designs database schemas and migrations that are safe to run on live data
• Writes idempotent jobs and handles retries and partial failures
• Treats authorisation as part of every endpoint, not an afterthought
• Adds logs and metrics that make incidents faster to resolve
• Can explain an API design to front-end and mobile colleagues

Generalist or language specialist?

For most products, a strong generalist who knows your main language well is more valuable than a niche expert. Choose a specialist when your stack demands it — for example Java or .NET in enterprise systems, or data engineers for heavy pipelines. Tell us your stack and we will match accordingly.

What back-end developers own

Back-end developers build the parts of a product users never see but always depend on: the database schema, business rules, APIs, background jobs, integrations with other systems and the security that protects all of it. Their decisions determine how fast pages load, how reliably payments and emails are processed and how easily new features can be added years later.

Red flags when hiring back-end developers

• No experience with database indexes or reading query plans
• Calls third-party APIs without timeouts or error handling
• Stores secrets in code or configuration files in the repository
• Has never designed an API others had to depend on
• Thinks of monitoring as something to add after launch

Scaling a back end the sensible way

1. Measure first

   Find real bottlenecks with profiling and query analysis before changing architecture.

2. Fix the database

   Indexes, better queries and caching usually give the biggest gains.

3. Move slow work to queues

   Emails, reports and integrations run in the background, not in web requests.

4. Scale horizontally

   Stateless application servers behind a load balancer.

5. Split services only when needed

   Separate services when team size or workload clearly justify it.

A sample brief for a back-end hire

• Language, framework and database already in use, and any planned changes
• The main systems the back end integrates with (payments, CRM, ERP, email)
• Current pain points: slow pages, failing jobs, fragile integrations or missing tests
• How code is reviewed, tested and deployed today
• Two or three outcomes expected in the first six weeks

Including real pain points helps you find a developer who has solved similar problems before rather than one who only matches a keyword list.

How back-end developers work with the rest of the team

Front-end and mobile developers depend on the back end, so a good back-end developer publishes API changes early, keeps documentation current and agrees error formats and pagination conventions up front. They also work with operations on deployment, backups and monitoring, and with product owners on edge cases — refunds, cancellations, permissions — that are easy to overlook when a feature is first described.

Back-end languages we place most often

We place back-end developers across Node.js, Python, PHP and Laravel, .NET, Java and Go. The language matters less than experience with your type of system — transactional business apps, high-traffic APIs or data-heavy platforms — so we match on both.

Tell us about your stack and we will suggest the right profile.
