Introduction

H2B Group, a Poland-based software development company, faced rising demand as it expanded projects in FinTech, MedTech, and GreenTech. With its engineering team already at capacity, the company needed senior Python developers who could contribute immediately to backend-heavy systems. Within six weeks, DevsData LLC delivered three experienced engineers, enabling H2B to sustain delivery speed and uphold technical standards during this critical growth phase.

Client profile

H2B Group is a Poland-based software development company that works with clients across FinTech, MedTech, GreenTech, FMCG, and other innovation-driven sectors. Their team of approximately 50 engineers focuses on building complex, backend-oriented platforms tailored to technically demanding industries.

The company’s projects often involve designing cloud-native architectures, integrating third-party systems, and developing scalable data pipelines. Many of their clients operate in regulated environments, which puts added emphasis on code quality, security, and long-term maintainability.

To support their internal roadmap and growing workload, H2B occasionally partners with external vendors to access high-caliber talent. These collaborations help them accelerate delivery without compromising technical standards. For this engagement, H2B selected DevsData LLC due to its proven track record in sourcing backend-focused engineers, extensive database of pre-vetted specialists, and ability to run a fast yet rigorous recruitment process aligned with demanding technical requirements.

Highlights:

• Software development company with a focus on backend-heavy systems for FinTech, MedTech, and GreenTech sectors.
• Headquartered in Poland with a team of approximately 50 engineers.

Challenge

H2B Group approached DevsData LLC during a critical stage of growth. The company was onboarding several new projects across FinTech and MedTech verticals and needed to strengthen its backend capacity without delaying delivery timelines. Their internal resources were already allocated across active streams, leaving little margin for error or slow recruitment cycles.

The technical expectations were high: candidates needed deep experience with Python, familiarity with cloud-native environments, and a demonstrated ability to work independently within fast-paced agile setups. Just as important were communication skills and reliability – H2B’s distributed team model meant that hires needed to integrate quickly and work with minimal supervision. The combination of backend depth and real-world delivery experience narrowed the talent pool significantly. The number of developers with specific FinTech or MedTech experience is estimated at 12% and 6% respectively of the total available market. The company was looking for a partner who could both understand the nuances of their requirements and deliver a rigorously vetted shortlist quickly to de-risk project deadlines.

Speed was a key constraint. H2B had already experienced delays with traditional hiring routes and could not afford to lose further time filtering unqualified applicants. The company was looking for a partner who could both understand the nuances of their requirements and deliver a shortlist fast, without compromising on quality. The pressure was on to balance selectivity with urgency – two factors that are rarely aligned in senior technical hiring.

H2B needed engineers who could integrate quickly, work independently, and handle complex backend tasks without slowing down delivery across active projects.

Beyond urgency and selectivity, the stack itself posed challenges. Engineers needed fluency not only in Python but also in frameworks like Django and Flask, experience with containerization tools such as Docker and Kubernetes, and strong database skills across Postgres and Redis This full stack backend expertise was critical for autonomy and required candidates who could handle complex, end-to-end tasks.

Goals

The engagement centered around sourcing and placing highly competent Python developers with hands-on experience in backend system design and integration. The hires were expected to contribute from day one, taking ownership of core components within larger client-facing platforms.

Beyond technical capability, the client prioritized engineers with a stable track record of long-term project involvement and consistent delivery in complex backend systems, as well as remote collaboration habits and adaptability to rapidly changing priorities. The goal was to bring in developers who would improve the team’s velocity and reduce the overhead of constant supervision or onboarding, with an objective to make new hires self-sufficient within their first two weeks.

To meet these expectations, DevsData LLC aimed to design a tightly controlled sourcing pipeline that minimized back-and-forth, filtered out low-fit candidates early, and presented only top-tier professionals ready to join on short notice.

Our approach

We began by assigning a compact, high-efficiency recruitment team with prior experience in Python and backend engineering placements. Within the first day, we conducted a role calibration session to translate H2B’s hiring criteria into sourcing logic, focusing on both hard skills (frameworks, infrastructure experience, and Git hygiene) and softer, often-overlooked signals, such as asynchronous communication proficiency and a history of remote work in product-oriented teams.

Leveraging our database of over 65000 pre-vetted tech professionals, we ran segmented searches across Central and Eastern Europe, the Baltics, and Portugal. This targeted approach allowed us to tap into regions known for strong engineering talent, cost efficiency, and cultural compatibility, accelerating time-to-hire while maintaining quality. In tandem, we initiated direct outreach campaigns on GitHub and LinkedIn, emphasizing the engineering complexity and autonomy offered by H2B Group. This combination allowed us to quickly zero in on candidates who matched not only the technical profile but also the team dynamic and pace.

A similar approach had proven successful in a previous collaboration with Kanary Inc., a cybersecurity startup that required a senior backend Python engineer capable of operating independently within a high-stakes, privacy-first environment. In just under five weeks, we placed a candidate who significantly accelerated backend delivery and supported the company’s long-term infrastructure. Drawing from this experience, we tailored the H2B search strategy to balance technical rigor with speed, ensuring the client received candidates ready to contribute from day one.

Our team maintained close coordination with H2B throughout the process, adjusting parameters based on early feedback and refining the shortlist criteria in real time. We also incorporated flexible interview windows to account for H2B’s internal constraints, ensuring that the speed of the process didn’t lead to logistical friction.

Execution and delivery

Candidate screening was divided into three phases: asynchronous review, behavioral alignment, and live technical validation. We began with detailed portfolio and codebase reviews, followed by asynchronous video submissions to assess communication clarity and self-management. Those who advanced were invited to a technical evaluation built around practical backend challenges, including API design, DB handling, and real-time error tracing.

Only candidates scoring above our internal benchmark proceeded to the final interview with H2B’s technical lead. This filter ensured that the client only invested time in profiles that had already been vetted across technical, cultural, and logistical dimensions. Each candidate was presented with a full dossier, summary of strengths and weaknesses, work samples, availability, and risk flags, enabling H2B to make informed decisions quickly.

The first hire was finalized within three weeks of project kickoff. Two additional senior Python developers joined over the following month and a half, rounding out the team with stable, experienced talent. All engineers have remained in their roles, contributing to long-term backend initiatives, with performance feedback from H2B described as highly autonomous and delivery-focused. The engagement has since evolved into an ongoing relationship, with DevsData LLC serving as a trusted sourcing partner for future technical roles.

Outcome

Over a span of six weeks, DevsData LLC delivered three senior Python developers who seamlessly integrated into H2B Group’s backend teams. The new hires took ownership of key components tied to financial data processing, platform integrations, and service-layer optimization. Their onboarding pace and independent work style allowed H2B to stabilize delivery timelines across several high-priority projects.

The recruitment cycle was efficient, with clear two-way communication, high candidate responsiveness, and minimal drop-off between interview stages. Out of more than 95 sourced candidates, 71 were shortlisted for initial screening, 27 advanced to technical validation, and 13 reached the final interview stage. The overall time-to-hire averaged just under two weeks per role, with a candidate dropout rate below 5% and a 100% offer acceptance rate. H2B reported stronger velocity in backend delivery and reduced hand-holding of new engineers – factors that directly improved the overall team output.

Following the initial success, the cooperation continued to evolve. DevsData LLC is now retained as a preferred staffing partner for senior and niche engineering roles, supporting H2B’s roadmap as new client projects are launched across regulated industries.

Highlights:

• three senior Python developers hired in approximately six weeks.
• Streamlined multi-stage process with a high technical-bar candidate pipeline.
• Extended partnership in place for future technical staffing needs.
