(Developers by technology)

Hire developers screened against the stack you actually run

Hire developers by technology rather than by job title: React, Node, .NET, Java, Python, Go, Flutter, React Native, Unity and data engineering. Screening tests the things your codebase will ask of them, and you run the final interview.

(Why the stack alone is not the brief)

Two React developers can be nothing alike. One has spent three years on a design system with strict accessibility rules; the other has shipped dashboards against a legacy API and knows exactly how to make a slow endpoint bearable. Both are genuinely senior. Only one of them fits your problem.

So the brief we work from describes the codebase rather than the keyword: what the system does, how old and how tested it is, where it hurts, and what the first three months of tickets look like.

(What we deliver)

Stacks you can hire for

Every engineer is a full-time employee here, working from Noida on your repositories and your board.

  1. React, Next.js, Vue and Node.js engineers for product front ends, design systems and API layers. Screening covers state management, rendering strategy and the accessibility and performance basics that separate a working page from a good one.

  2. C# and Java engineers for enterprise back ends: ASP.NET Core, Spring Boot, SQL Server and Oracle. Useful where the system is older than the team and the real skill is changing something large without breaking the parts nobody documented.

  3. Python for services, scripting and anything touching data; Go where throughput and memory behaviour matter. Screening looks at concurrency, error handling and test discipline rather than familiarity with a particular framework.

  4. Cross-platform engineers who have shipped to both stores, plus native Swift and Kotlin where the app needs it. Release process, offline behaviour and store review experience are part of the assessment, not an afterthought.

  5. Unity engineers from the studio’s game side, working on gameplay, tooling, optimisation and simulation or training builds. Profiling on target hardware is the part most CVs overstate, so it is the part we test hardest.

  6. Engineers for pipelines and warehouses: SQL, Spark, dbt, Airflow, and the cloud data platforms on AWS, Azure or Google Cloud. Modelling and data quality are assessed alongside the tooling, because that is where pipelines actually fail.

(How we work)

How the work runs

Every engagement is scoped in phases, priced per phase, and reviewed with you at the end of each one.

  1. 01

    Discovery

    We map the problem, the systems around it and what a good outcome looks like, then scope the work in phases you can stop after.

  2. 02

    Design

    Flows, architecture and interfaces agreed before anyone writes production code.

  3. 03

    Build

    Two-week increments, a working environment you can open, and a demo at the end of each one.

  4. 04

    Testing

    Functional, performance, security and accessibility checks run through the build, not bolted on at the end.

  5. 05

    Launch

    Deployment, monitoring, documentation and the handover your team needs to run it.

  6. 06

    Support

    Fixes, updates and the next set of features, at an agreed monthly capacity.

(Why Team of Keys)

How screening works, and what a good match looks like

A CV tells you what someone has been near. These steps are how we work out what they can do, and how you confirm it before committing.

  1. 01

    The brief starts with your code

    Before searching, we ask about the codebase, the tests, the deployment process and the first tickets. A match is someone who has worked at that scale and with that level of legacy, not simply someone who lists the framework.

  2. 02

    Technical screening by engineers

    Candidates are screened by a senior engineer in the same stack: a practical exercise or a walk through code they have written, plus questions about debugging, trade-offs and what they would refuse to do.

  3. 03

    Your interview decides

    Shortlists arrive with a written technical summary and a code sample. You interview, you set the bar, you say yes or no. Nobody is assigned on our assessment alone.

  4. 04

    A trial fortnight

    The first two weeks are a fit period. If the engineer is wrong for your codebase or your working style, tell us inside that window and the time is not billed.

  5. 05

    English and the working day

    Written and spoken English is assessed, because most of the communication will be asynchronous. Overlap hours with your team are agreed in the contract rather than assumed.

(FAQ)

Questions, answered

Yes, and you should. Shortlisted candidates come with a technical summary and a code sample, then sit whatever interview process you normally run — pairing, take-home, system design, a conversation. Our screening narrows the field; your interview makes the decision. If nobody on the shortlist convinces you, we search again at no cost.

The first two weeks of each engagement are a fit period. If the engineer is not right for your codebase or your way of working, tell us within that window and you are not billed for their time. Most mismatches show up in the first sprint, which is why the window sits where it does.

Ask. The list covers what clients hire most often, not the limit of the bench, and rarer skills — embedded C, Rust, Elixir, SAP ABAP, mainframe COBOL — are sourced against a specific brief. Scarce stacks take longer to fill, and you will be told that at the start rather than after a month of silence.

Seniority is described by what somebody has shipped and owned rather than by a title, because titles inflate at different rates across companies. A senior engineer in the same stack runs the technical screen, and the written summary tells you where the candidate is genuinely strong and where they are not. Your interview confirms it.

Everyone works from the Noida office on IST, on managed and encrypted laptops. The overlap window with your team is agreed in the contract: most of a shared working day for UK and EU clients, a shifted start for US eastern time, and a late shift where west coast hours are needed.
