Our method for recruiting best Kotlin developers 

From the initial call to the first commit, our process is built to help you hire Kotlin programmers quickly and efficiently.

 

01

Calibration

We learn your requirements, values, and objectives. This call establishes non-negotiable skills and cultural traits.

02

Sourcing

HR specialists tap referral networks, proprietary ATS, and conferences to pinpoint high-potential Kotlin developers for hire.

03

Vetting

Each candidate completes a profile review, language check, live coding session, and behavioral interview. Only the strongest proceed to you.

04

Hiring and onboarding

We finalize the offer and compliant contracts in the engineer’s location, then set up equipment, access, and sprint workflows. Your new Kotlin developer starts pushing code right from the first iteration.

05

Retention

Regular check-ins, reviews, learning support, and growth opportunities keep your team engaged and growing alongside your goals.

Tackling major hiring challenges with Newxel

Common concerns, straight answers — here’s how Newxel handles the friction points of remote hiring.

Timeframe for hiring

Conventional HR cycles stretch to three months. Our model cuts that to one sprint: first CVs arrive within five business days, contract signed within a month. The pipeline is pre-loaded, so you’re never waiting for a cold search to start from scratch. Hire Kotlin developer sooner, launch MVPs ahead of schedule.

How do I source high-quality Kotlin developers?

Every candidate clears a structured gate before you see their profile:

  • Kotlin-specific technical screening
  • Behavioral and culture-fit interview

Only top performers reach your desk. No volume padding, no filler profiles — solely engineers who can contribute from sprint one.

How can I prevent losing developers mid-project?

We design retention to work naturally from day one, not as an extra. On top of solid pay, engineers get:

  • A career path that matches your product goals
  • Health coverage and wellbeing support
  • Regular one‑on‑ones with their HR contact

Our client retention sits at 98% — well above average.

Who handles compensation, benefits, and legal?

Newxel covers the full back-office stack: salary processing, tax reporting, leave tracking, local labor law compliance, and data security. You run the product; we run the operations. No ambiguity, no separate vendors.

Flexible growth

Need to scale from two engineers to ten? Hire Kotlin engineer by activating a new search within the same vetted talent pool, using your established onboarding template. No delays, no extra overhead — just a larger team ready to sprint.

How do I ensure programmers match my project vision?

We align engineers with your project goals through shared KPIs, regular quarterly alignment sessions, and real-time reporting dashboards that keep progress fully transparent. This ensures every Kotlin engineer stays focused on your strategic objectives.

If priorities or direction change, we adapt the team’s focus quickly—without the need to renegotiate contracts—so execution always stays aligned with your vision.

Need-to-knows for recruiting Kotlin talent

How much does it require to recruit a Kotlin developer?

Rates vary by stack. Mid-level Kotlin developers in CEE earn competitive salaries, while senior engineers in Western Europe may reach €75K+.

Add Newxel’s fixed fee, and you still save 20-40% versus in-house hiring in the UK. 

How promptly can I find a Kotlin developer

First resumes land in your calendar within five working days, allowing you to quickly start evaluating pre-vetted candidates. From signature, full onboarding and boot-up typically take just 2–4 weeks, so your engineer can be ready to contribute in a very short timeframe.

How do you maintain standards?

We ensure quality through a structured, multi-step evaluation process. Candidates go through CV screening, a Kotlin coding assessment, a live technical interview with a senior engineer, and a final team fit conversation to validate both skills and collaboration ability.

After onboarding, standards are maintained through regular monthly check-ins and KPI tracking, ensuring engineers stay aligned with your goals and consistently deliver at a high level.

Do you provide programmers in specific markets?

Our core coverage includes Ukraine, Poland, Bulgaria, Romania, Spain, Portugal, Israel, and Turkey, giving you access to strong engineering talent across Europe and nearby tech hubs.

This regional flexibility helps you build distributed teams that still work seamlessly with your in-house operations.

What hiring options are available?

We offer flexible outstaffing-based hiring options to support different scaling needs. You can choose IT staff augmentation, dedicated development teams, or R&D team setups depending on your project requirements.

In all models, you retain full control over the engineers and day-to-day work, while we handle sourcing, HR, payroll, and operational support.

How do you ensure project continuity if a developer leaves?

We prioritize stability from the start. Strong retention and structured team setup reduce turnover risk significantly—our engineers have a 98% retention rate and stay on projects for an average of 3.5 years, ensuring long-term continuity and deep project knowledge.

In the rare case a developer does leave, succession planning is already in place. The account manager quickly initiates a replacement process and backfills the role within one month at no additional recruitment fee, ensuring minimal disruption to delivery.

How do you guarantee results from day one?

Set-up completes workflows before the developer starts. Sprint rituals are shared, allowing code commits in the opening sprint.

Hire Kotlin developers now with Newxel and convert big ideas into shipped features — sooner, better, and cost-effectively.
