We’re hiring a capable, execution-focused API & Integrations Engineer to develop a production-grade API platform and build out a series of critical fintech-related integrations. You’ll help build out our API solution and connect our system with external services that drive messaging, personalization, and customer lifecycle automation.
This is a hands-on backend engineering role ideal for someone who understands real-world systems integration—how to work with third-party APIs, normalize data, and build reliable, well-documented services.
You can join on a project basis (3–6 months with scoped milestones), or as a full-time contributor with the opportunity to grow into a more senior or permanent role as we scale.
Key Responsibilities
* Design and develop REST APIs to expose customer, event, and trigger data to internal and external systems.
* Build secure, reliable fintech integrations by consuming third-party APIs and enabling real-time or near-real-time data flows.
* Handle authentication flows and payload mapping, working with APIs that use OAuth2, API keys, and token-based auth.
* Write and maintain API documentation using tools like Swagger or OpenAPI.
* Monitor and optimize integration performance, ensuring low latency, resilience, and clear error handling.
* Collaborate with front-end, product, and QA teammates to deliver complete, testable features.
* Own the integration codebase, with responsibility for maintenance, refactoring, and extensibility.
Required Skills and Experience
* 3–5+ years of backend development experience using Node.js, Python, Go, or equivalent.
* Strong background in building and consuming REST APIs; good understanding of API design patterns, authentication, and webhooks.
* Experience integrating with third-party platforms in fintech, banking, CRM, or martech domains.
* Familiar with async job handling and messaging systems (e.g. queues, retries, event consumers).
* Proficient in writing integration and unit tests, using Git, CI/CD pipelines, and API testing tools.
* Ability to work independently from spec or documentation and deliver reliable, production-ready code.
* Must be physically located in the GMT to GMT-2 time zone and available during standard GMT working hours.
Nice to Have
* Prior experience integrating with CRMs, banking APIs, marketing tools, or customer data platforms.
* Exposure to pub/sub architectures, message queues, or data pipelines.
* Experience with schema validation, API monitoring, or developer-facing API portals.
* Familiarity with fintech security and compliance best practices (tokenization, encryption, audit logging).
What We Offer
* Flexible work model: project-based or full-time, depending on your preference and availability.
* Clear roadmap with milestone-based delivery, well-scoped integration targets, and limited distractions.
* Growth opportunity: Full-time role may evolve into senior engineer or technical owner of the API layer as we scale.
* Direct access to product and engineering leads to unblock issues quickly and ensure focus.
* An execution-first culture with a small but close and capable team.
