What are back end developers?

A back-end developer (or backend engineer) owns the server-side path: data models, APIs, auth, jobs and the services your clients and apps call. A back end specialist should leave written contracts and runbooks so production is not tribal knowledge. They do not replace your product owner.

They typically own

  • Schema and migrations
  • API contracts and versioning
  • Auth, roles and permissions
  • Background jobs and queues
  • Observability for the services they ship

They share with others

  • Incident response with your on-call process
  • Performance work with whoever owns the client
  • Security reviews with your security owner

They should not own alone

  • Product priority without your backlog
  • Production secrets outside your vault
  • Release approval if your process requires a separate owner
Scope

What you can hire them for

Hire dedicated backend developers for greenfield APIs, live products, or backend consulting on architecture before you fund a seat.

New product development

Greenfield APIs and services that your mobile or web clients will call.

Existing application enhancement

Features, refactors and debt pay-down inside a repository you already run.

Migration and modernisation

Framework upgrades, service splits and data moves with rollback plans.

API and integration work

Third-party systems, webhooks and contract tests against partners.

Performance optimisation

Query plans, caching and load behaviour under real traffic shapes.

Maintenance and support

Ongoing fixes, dependency updates and on-call participation under your rules.

Stack

Back end stack developers we staff

Teams commonly hire Node.js developers, Python developers, PHP developers, Laravel developers, Django developers, .NET developers, Ruby on Rails developers and Spring Boot developers as dedicated backend seats when that matches the repo. Availability of a specific seat varies by week. For product builds rather than seats, see our mobile app development services.

Languages and frameworks

Node.js Python Django PHP Laravel .NET Ruby on Rails Java Spring Boot

Data and APIs

MongoDBMySQLRESTJSON APIsQueues

Expert block

What breaks first as your user count grows

When traffic rises, failure usually follows a predictable order. A backend developer you hire should be able to walk this list against your codebase without guessing.

1. N+1 queries

List endpoints that load related records one row at a time look fine in staging and collapse under concurrency. Ask how they find and prevent N+1 before it reaches production.

2. Connection pools

Database and HTTP client pools exhaust before CPUs do. Ask what pool sizes they set, how they size for workers versus web processes, and what saturation looks like in metrics.

3. Cache invalidation

Stale reads and thundering herds appear after you add caching to fix latency. Ask how keys are scoped, how writes invalidate, and what happens when the cache is cold.

4. Background jobs

Retries without idempotency double-charge users and flood partners. Ask how jobs are made safe to retry, how dead letters are handled, and who watches queue depth.

5. File storage

Local disks fill; unsigned URLs leak; large uploads block request threads. Ask where binary objects live, how access is signed, and how virus and size limits are enforced.

Profiles

What a strong backend profile looks like

Look for

  • Shipped APIs with stated contribution, not only stack lists
  • Clear talk about failure modes under load
  • Comfortable explaining trade-offs in your interview

Ask in the interview

  • How they would find an N+1 in a pull request
  • How they design a job that can safely retry
  • What they would check first when p95 latency doubles

A good answer sounds like

Specific systems, metrics and past incidents. Vague claims about “scalable architecture” without measurement are a weak signal.

Red flags

Cannot describe ownership boundaries, dismisses observability, or treats your production process as optional.

Seniority

Seniority described by capability

Mid

Delivers well-scoped tickets in an existing service, writes tests, asks when contracts are unclear.

Senior

Owns a service area end to end, designs for failure, reviews others with concrete risk notes.

Tech lead

Sets interface and operational standards across services, unblocks others, keeps architecture decisions written down.

Seniority here is capability, not a year count. “Expert” and “senior” labels only stick when the interview proves the capability.

Fit

When you need a backend developer, and when you do not

Hire when

You have an API or data backlog your current team cannot absorb, you need to hire a dedicated backend developer under your direction, or you are opening a new service with clear ownership.

Do not hire when

You only need a fixed deliverable by a date and do not want to manage a person. That is a project engagement, described on the hire developers hub, not a dedicated seat.

Models

Hiring and engagement models

Hire remote back end developers, hire offshore back-end developers, a single dedicated seat, a back-end developers team, or a short backend consulting pass before you fund capacity. The hub explains what each model commits you to, who directs the work, how change is handled and what scaling down means. Start with hire developers if you are still choosing the arrangement.

Joining

How to hire a backend developer

How to hire a remote backend developer for your project: free functional and technical discovery calls, then a mutual NDA, role definition, profile shortlisting, your technical interview, selection and onboarding. No joining timeline is promised on this page. Confirm notice and start dates in writing before you rely on them.

01

Discovery calls

Functional and technical calls at no charge.

02

Mutual NDA

Before detailed product or profile discussion.

03

Role definition

Ownership, stack, overlap window and success criteria.

04

Shortlist and your interview

You decide who advances and who receives an offer.

05

Onboarding

We handle employment paperwork; you grant repo and tool access.

Collaboration

How our developers work inside your existing team

Your product owner or PM sets priority. The developer works in your Git repository, follows your code review rules, passes your QA gates and ships through your CI/CD. Chat, tickets and CI tools are examples you choose, not a fixed Mobulous stack.

FAQ

Questions before you hire a backend developer

How do I hire a backend developer for my project?

Book a free discovery call, sign a mutual NDA, define the role and stack, review shortlisted profiles, run your own technical interview, then onboard into your repo and tools. The same path applies when you hire a back end developer for an existing product versus a new build.

What are back end developers responsible for?

Server-side application code, data, APIs, jobs, auth and the operational behaviour of services your clients call. They work under your product owner; they should not be the only person who understands production without a written runbook.

How to hire a remote backend developer?

Define overlap hours, ownership and success criteria, then interview for communication and production judgement as hard as stack fit. Remote and offshore back-end developer seats from Mobulous work in your Git, chat and CI under your direction.

How much does it cost to hire a backend developer?

Cost depends on seniority, stack, exclusivity and engagement model. This page does not publish rates. Use the free discovery call for a quote matched to the role you define.

Will the backend developer work only on my backlog?

Under a dedicated seat, yes: they work under your direction on your priorities. Part-time or hourly seats share capacity by agreement. Confirm exclusivity in the contract before you rely on it.

Do I interview them myself?

Yes. We shortlist; your technical interview decides who joins.

Who owns the code they write?

Source code and IP for work produced under the engagement transfer on delivery, as written in the contract.

How do I choose between one developer and a team?

One developer fits a clear backend backlog with an existing product owner. A team fits when you also need QA or design capacity under the same arrangement. The hire developers hub compares models.

Ready to hire backend developers?

One developer, a back-end developers team, or help choosing the model. Free discovery. Mutual NDA before deep detail.
