Our process
How We Help You Hire Backend Developers
KPS can either assign an available developer from our core team or recruit a new specialist around your requirements. The route depends on the required backend stack, seniority, responsibilities, and availability. If a matching specialist is already on the KPS core team, they can start within 7 days, without a lengthy hiring process. Dedicated backend developers for long-term projects are recruited specifically for your team in several steps.
STEP 1:
Kick-Off Call
We define the backend stack, seniority, responsibilities, workload, time-zone overlap, and working model. These requirements form the candidate profile we use throughout the search.
STEP 2:
Sourcing
We search our internal network and external talent channels against the agreed candidate profile. The first week or two can be deliberately quiet: we source candidates and run the early screening without taking up your team’s time. You won’t receive raw CVs. Candidates reach you only after they have passed our HR and technical interviews.
STEP 3:
HR Interview
We check English proficiency, communication skills, availability, salary expectations, remote-work experience, and practical fit with your working model.
STEP 4:
Technical Interview
KPS engineers assess the technical skills relevant to your role, including backend architecture, languages and frameworks, APIs, databases, integrations, testing, performance, and security. The assessment is adapted to the stack and responsibilities defined for the position. Most candidates are filtered out at this stage, so you usually meet two or three finalists: candidates whose technical ability has already been evaluated by engineers.
STEP 5:
Client Interview
You interview the shortlisted developers directly, evaluate their fit with your team and product, and make the final hiring decision. KPS coordinates the interviews and handles any follow-up questions.
STEP 6:
Offer & Onboarding
KPS confirms the terms with the selected developer and handles the employment, contract, payroll, and administrative setup so they can join your team.
STEP 7:
Ongoing Support
After the developer starts, KPS stays involved on the employment and HR side. We keep in touch with both sides and help address workload, communication, or cooperation issues throughout the engagement.

Vetting
What We Vet Backend Developers For
When you hire backend engineers through KPS, we assess how they work with real production requirements, not just their knowledge of a particular framework. We look at their ability to work within an existing codebase, make sound technical decisions, and build backend systems that remain reliable and maintainable as the product grows.
Backend Architecture
We assess how developers structure application logic, separate responsibilities, manage dependencies, and make backend systems maintainable as products grow.
Databases & Data Modeling
We evaluate how developers design data models, write and optimize queries, choose appropriate storage approaches, manage migrations, and maintain data consistency.
APIs & Integrations
We assess REST, GraphQL, authentication, third-party integrations, service communication, error handling, and API design practices relevant to the product.
Performance & Scalability
We check how developers identify backend bottlenecks, optimize database and application performance, work with caching and asynchronous processing, and design services for increasing workloads.
Security
We evaluate practical understanding of authentication, authorization, data handling, input validation, API security, secrets, and common backend security risks relevant to the role.
Testing & Maintainability
We assess unit and integration testing, debugging, code structure, documentation, error handling, and the developer’s approach to making backend code easier to review, maintain, and extend.

Case studies
What Clients Say About Working With Our Backend Developers
Our backend experience comes from products already used in production. Here are examples of how KPS developers have handled backend systems, integrations, business logic, and technically complex product requirements.
BetterCare
BetterCare is a healthcare management platform that needed to modernize a difficult-to-maintain legacy product while continuing to support its existing clients.
Backend challenge: The platform was running on an outdated PHP codebase that was becoming difficult to maintain and scale. Rebuilding the entire product from scratch was not practical because the existing system had to remain operational.
KPS contribution: KPS audited the existing codebase and moved the backend from pure PHP to Laravel as part of a gradual modernization strategy. The approach allowed the team to improve the platform’s performance and security without requiring a complete rebuild.
Stack: PHP, Laravel
Outcome: BetterCare continued developing the existing product while modernizing its technical foundation. During the broader KPS engagement, the company grew from 5 to more than 30 engineers and reduced engineering costs by 53%.
Waddington’s
Waddington’s is a Canadian auction house whose digital platform supports online auctions and remote appraisal services.
Backend challenge: The new application needed reliable communication with the existing Node.js backend while securely transferring media and keeping scheduling, client, and auction-item data synchronized.
KPS contribution: KPS developed custom RESTful APIs connecting the React Native application with the Node.js backend. The APIs support scheduling, media storage, and client-item record updates, with media transferred to the backend through encrypted channels.
Stack: Node.js, RESTful APIs
Outcome: The platform supports nearly 100 online auctions annually, while the mobile app has attracted more than 3,700 users. 80% of Waddington’s transactions are now completed through the app.
Engagement options
Hire Backend Developers the Way Your Team Needs
Whether you need to hire backend developer for a specific technical task or expand backend capacity for long-term product development, KPS can adapt the hiring setup to your team and requirements.
One Backend Developer
Hire a backend developer to add a specific language, framework, architecture, or domain skill to your existing team. This works well when you need targeted support without changing your current delivery setup.
Several Backend Developers
Add several remote backend developers when your current team needs more delivery capacity across multiple services, integrations, or product areas. KPS can recruit developers around the same or complementary technology stacks while keeping the hiring and employment side centralized.
Dedicated Backend Team
Create a dedicated team for a separate product stream, ongoing platform development, or a long-term roadmap. Backend developers can be part of a cross-functional setup, alongside fullstack engineers, AI/MLOps engineers, or a forward deployed engineer, built around your product rather than a fixed frontend/backend split. The developers work as an integrated part of your organization under your management, while KPS handles recruitment, employment, payroll, HR, and retention.
Pricing
How Much Does It Cost to Hire a Backend Developer?
The cost depends on the engagement model. A specialist from the KPS core team works at a Time & Material rate. A developer recruited for your team is paid their actual monthly compensation, plus a fixed KPS service fee shown as a separate line. The fee is not a percentage of salary and does not increase when the developer gets a raise. Compensation depends mainly on seniority, technology stack, and the experience your product requires; backend engineers with expertise in architecture, high-load systems, cloud infrastructure, security, or complex integrations typically earn more.
*Example monthly compensation based on KPS’s 2026 salary benchmarks for the Ukrainian engineering market, before the fixed KPS service fee. These are reference figures, not fixed rates: actual compensation depends on seniority, stack, domain experience, and hiring requirements. Core-team specialists are billed at a Time & Material rate instead.
