Driving the evolution of payments, Unlimit is transforming its infrastructure from human-operated fintech into AI-native financial infrastructure — where APIs are consumed by machines, integrations are negotiated by agents, and systems evolve continuously through intelligent automation. Our next users are not only humans. They are AI agents acting on behalf of humans and businesses.
Unlimit serves more than the needs of businesses today; we are building the nervous system for a borderless global economy.
We are seeking a technically-adept Implementation Specialist to join our fast-paced Fintech environment. You will be responsible for the technical configuration and integration of merchant terminals and wallets, ensuring flawless execution while maintaining strict adherence to established SLAs and SOPs. This role is designed for a "builder" who isn’t satisfied with manual work and has the drive to automate repetitive tasks using AI principles and modern tooling.

    What you will do

  • Technical Integration & Configuration: Execute complex API integrations (REST) and manage the technical setup of digital wallets and physical terminals.

  • API & Endpoint Validation: Use tools like Postman to validate endpoints and ensure seamless data flow between merchants and our PSP systems.

  • Automation & AI Collaboration: Work in parallel with AI-driven workflows to identify manual bottlenecks. Review and analyse automation results to diagnose and fix broken scripts or API callback errors.

  • Certificate Management: Handle the lifecycle management of digital certificates to ensure secure and uninterrupted gateway configurations.

  • Technical Troubleshooting: Conduct deep-dive technical analysis into integration errors or configuration mismatches to provide rapid resolutions.

  • SLA & Quality Adherence: Meet all project deadlines, volume targets, and SLAs while following established SOPs.

  • Documentation: Maintain clear, concise project documentation in Confluence and track all active work streams via Jira.

    • Technical Requirements & Experience

  • Industry Experience: 1+ years in FinTech, specifically with PSP systems, Gateways, and Merchants.

  • Tooling: Proficiency in Salesforce, Jira, Confluence, and Postman.

  • Technical Skills: Solid understanding of REST API basics, API endpoints, and troubleshooting callbacks.

  • Hardware/Soft-pay: Direct experience with Terminal and Wallet configuration and API certificates.

  • Communication: Exceptional verbal and written English for technical coordination and stakeholder updates.

  • Mindset: Understanding of AI principles for process optimization and high adaptability to shifting priorities.

    • Soft Skills & Attributes

  • Initiative: A self-starter who actively looks for ways to improve system efficiency without being prompted.

  • Analytical Rigor: A natural problem-solver who enjoys deconstructing complex technical issues.

  • Deadline Driven: A disciplined approach to meeting timelines and adhering to strict operational standards.

  • Adaptability: Ability to thrive in a dynamic, high-growth environment where schedules and priorities shift rapidly.
