We invite a high-caliber Technical Team Lead who thrives on technical challenges and knows how to communicate effectively with CTO-level stakeholders to join our team. This hybrid role is split 50/50 between onsite and remote work. As the onsite anchor for a critical payment harmonization platform, you'll oversee and mentor a high-performing team bridging complex C/Perl legacy systems with modern enterprise standards. Your focus will be on collaborating with technical leadership, ensuring architectural integrity, and delivering high-throughput, reliable payment solutions fully aligned with client needs.

What's in it for you:

• Work on a mission-critical, real-time payment platform powering high-volume, multi-processor transactions
• Modernize a legacy C/Perl system into a robust, enterprise-standard architecture
• Collaborate with senior leadership to drive decisions that shape the platform and maximize client success

Is that you?

• 6+ years working with distributed payment systems and high-throughput processing
• 2+ years in the payments domain, with a solid understanding of the payment lifecycle (authorization, capture, settlement)
• Experience with payment orchestration, gateway integrations, tokenization, smart routing, retries, and multi-processor environments
• Experience with authorization and settlement pipelines
• Knowledge of card networks (Visa, Mastercard, Amex) and ISO 8583/SPDH messaging
• Understanding of PCI DSS compliance
• Experience with PostgreSQL and Unix-based systems, and familiarity with networking fundamentals
• Effective collaboration with senior engineers, architects, and technical leads in Agile teams
• Strong communication skills and ability to turn technical challenges into clear business plans
• Proactive, solution-oriented, and adaptable mindset, with openness to new ideas and constructive feedback
• Upper-Intermediate English level and native-level Croatian proficiency

Desirable:

• Experience with low-level C cores and complex Perl data-transformation layers
• Experience with C and Perl or willingness to learn
• Experience with Google Cloud Platform (GCP)

Key responsibilities and your contribution:

In this role, you'll be the face of the Dev.Pro partnership, identifying project development areas and ensuring the team delivers tangible, high-efficiency results that exceed client expectations.

• Lead the onsite payment team in its daily Agile execution
• Coordinate with senior engineers, architects, and CTO-level stakeholders to align team output with strategic goals
• Oversee payment platform delivery, including orchestration and gateway integrations
