Overview
Join a fast-growing technology organization redefining productivity paradigms in software engineering. This role offers a flexible, distributed model of global operation with strong career opportunities and high-caliber collaboration.
We are looking for a highly skilled and hands-on Lead Java Engineer to lead a focused engineering initiative centered on payment gateway integration. This role combines technical leadership with active coding responsibilities within a semi-autonomous structure to ensure fast, efficient delivery. You will guide implementation best practices, support junior engineers when needed, and own solution design and code quality.
Key Responsibilities
* Lead the technical design and development of integrations with multiple payment gateways (preference for Worldpay).
* Own and implement encryption/decryption logic using industry-standard security protocols.
* Translate and transform data formats for reliable communication with payment services.
* Interpret, navigate, and apply complex API documentation with minimal support.
* Troubleshoot systems at the network level to ensure robust and secure integrations.
* Contribute directly to coding, code reviews, and architectural decisions.
* Operate confidently in a cloud-hosted environment (primarily Azure).
* Support light administrative tasks related to project ramp-up, where needed.
Must-Have Skills
* Expert-level proficiency in Java.
* Proven experience integrating with payment gateways.
* Strong understanding of encryption/decryption techniques and secure coding standards.
* Experience resolving low-level systems and networking challenges.
* Ability to work independently and make sound technical decisions.
* Comfortable translating product needs into scalable technical solutions.
* Cloud experience in Azure and AWS
Nice to Have
* Experience using observability tools like Grafana or OpenTelemetry.
* Familiarity with agile delivery in lean, distributed team environments.
* Lead a small, semi-independent engineering initiative.
* Report to a Product Leader.
* Collaborate with other senior engineers based in the UK and Hungary.
Location
Spain, Portugal, or UK, Central London or Hertfordshire (hybrid). The position requires travel to the UK for project-related activities.
Benefits
* The chance to join an organisation with triple-digit growth that is changing the paradigm on how software products are built.
* The opportunity to form part of an amazing, multicultural community of tech experts.
* A highly competitive compensation package.
* Medical insurance.
