For enterprise systems where a slow query costs real business hours

Hire.NET Developers

The .NET ecosystem gives you enough abstraction to write something that works without understanding why, until it stops working under real load. These engineers are matched to that specific gap, evaluated on the work above, and onboarded inside the process your team already runs.

  • Profiles typically within two business days
  • Replacement Assurance: If an engineer is not the right fit, a replacement from our own team starts within ten business days of your request, at no extra cost
  • You interview before placement if you want to
  • At least four hours a day inside your core working hours. Two hours plus a daily written handover for the US West Coast
  • 14-Day Risk-Free Trial: For your first engineer on a time-and-materials engagement. Up to 14 calendar days or 80 logged working hours, whichever comes first. End within the trial and pay nothing for trial hours. Continue beyond it and those hours are billed at the agreed rate. Unpaid trial work remains ours if you stop

01Published, not promised

The assessment behind every engineer we send.

The .NET bar is published rather than promised: five competencies, real tasks from real failure modes, and the weak signals spelled out. Use them in your own rounds if useful.

What we listen forWhether they understand the threading model or just sprinkle async everywhere.

The task we set

Here is a controller action that deadlocks intermittently under load. Find the cause and explain the specific condition that triggers it.

What strong sounds like
Identifies a blocking call on an async path or a context-capture issue precisely, not a vague reference to threading being complicated.
What gives us pause
Suggests adding ConfigureAwait everywhere without understanding which specific call is actually causing the deadlock.

02Who you actually meet

The bench, priced by seniority.

Three seniority tiers, priced honestly, and the engineers who fill each one today. Real names and photos take their place as soon as we can share them, and the standard stays exactly the same.

Engineer

Features scoped tightly enough to ship inside your review bar, every time.

The right first hire when your seniors already set the standard.

$2,500–3,200per month

Senior

The hard module nobody else wants to own, taken end to end.

Ownership of a surface, without adding a manager to your headcount.

$3,500–4,400per month

Lead

The workstream's decisions, made daily, so nothing waits on a meeting.

One accountable voice for a pod or initiative that can't afford to drift.

$4,700–5,900per month

03From stated problem to first change

Four steps, each closing on evidence.

Four steps, each ending in something you can audit: brief, shortlist, watched assessment, first merged change. Exit freely between any of them.

  1. Define the performance problem

    We map what the system actually needs to hold under real query volume and concurrency. The role brief describes the problem to solve, not a list of NuGet packages to know.

    A brief your leads sign

  2. Match against your stack

    Candidates are screened against your framework version, your data layer and your review culture. Three engineers who fit beat thirty who list the right certifications.

    Three fits, not thirty CVs

  3. Assess on the real tasks

    The async-deadlock and EF exercises can run with your engineers watching every step. You see judgement under real performance conditions, not a rehearsed design pattern answer.

    Evaluation you can watch

  4. Onboard inside your process

    Access, standards and a first bounded change to a real service. Continuity cover means any departure is bridged by us, with a briefed successor rather than an empty sprint.

04Evidence and proof

Engineers who found the query nobody else looked at.

.NET proof is page loads that got fast and services that stopped needing scheduled restarts. Every record here waits for written client approval before production.

05Three shapes, one standard

Add an engineer, a backend pod, or a practice.

A named engineer inside your reviews, a backend pod with its own lead, or the .NET practice for platform-scale work. The right door depends on what the work is, and we say which.

  • One named engineer

    A single .NET specialist inside your direction and your reviews. The smallest commitment and the most common starting point.

    Team extension

  • A backend pod

    A led pod that owns a bounded slice of the platform, from contracts through deployment. You set priorities and acceptance while the pod carries delivery.

    Delivery pods

  • The practice, not the person

    When the work is a .NET platform build or modernisation rather than a role to fill, the .NET development practice carries delivery accountability instead.

06Straight answers

Asked before a .NET hire is signed.

Ask us directly Or browse every role
What does a .NET engineer actually do day to day?

Designs and maintains ASP.NET Core services, reasons about async correctness and Entity Framework performance, manages dependency injection lifetimes correctly, and keeps business logic testable independent of the database. The unglamorous majority of the work is the query patterns that quietly get slow over time.

Do you hire for legacy .NET Framework or modern .NET?

Both, and many engagements involve moving from one to the other safely. The evaluation focuses on correctness and performance judgement that transfers across versions, then confirms hands-on familiarity with whichever your codebase runs.

Can we run our own interviews as well?

Yes, add any rounds you want. The published tasks are reusable, and clients often sit in on the EF-performance exercise specifically.

How fast can a .NET engineer start?

Days to shortlist from a bench we evaluate continuously. Actual start dates then track your Azure and repository access approvals.

Who manages the engineer day to day?

You manage the work; the engineer sits inside your ceremonies and standards. We hold continuity, payroll and the replacement commitment.

What if the engineer is not the right fit?

Early flags cost you nothing: replacement is our expense, and the follow-up candidate is briefed on the precise mismatch.

Do your .NET developers use AI tools when writing code?

Yes, inside clear rules. AI drafts controllers, mappings and test scaffolds quickly; the engineer remains answerable for async correctness, EF query behaviour and every pull request. Client code never receives machine output that a person has not defended.

How does pricing work for a hired .NET engineer?

Seniority bands above, per-engineer confirmation with the shortlist, monthly billing, notice-period exit. No fee exists before an interview happens.
