About Fadir Technologies

Fadir Technologies is building a next-generation platform. Fast, modular, and designed for multi-brand scalability, on Cloudflare Edge with TypeScript, Workers, Durable Objects, D1, KV, and R2. Evolving beyond a legacy Laravel PHP / AWS monolith toward real-time, low-latency scalability.

The Role

Lead our third-party integrations roadmap with a focus on PSPs and GSPs. You’ll design, implement, and own resilient, secure, and well-documented integrations. Covering APIs, reconciliation, and certification, so product teams can move quickly with confidence.

What You’ll Do

- Own PSP & GSP integrations end-to-end: Discovery, technical scoping, implementation, certification, and production rollout.

- Implement robust API layers: Design and implement endpoints, workflows and webhooks.

- Payments & transaction flows: Authorization/capture/refund/void flows, payout and settlement handling, reconciliation against provider reports, dispute/chargeback handling, and ledger consistency.

- Integration quality & reliability: Contract tests, provider simulators, automated e2e testing flows, observability, and alerting.

- Security & compliance: Secrets management, data minimization, audit logging, and alignment with relevant standards.
- Partner management: Coordinate with provider tech teams and oversee the integration process.


What You’ll Bring

- Experience building and maintaining third-party integrations at scale (preferably PSPs and/or GSPs).

- Strong TypeScript/Node.js skills

- Understanding of Cloudflare Workers or similar distributed systems.

- Deep understanding of API design, transactional systems, idempotency, retries, and other resilience patterns.

- Experience with payments lifecycle, reconciliation, and secure handling of sensitive operations.

- Excellent partner-facing communication.
- Proven ability to turn partner docs into clean, well-tested integrations.


Nice to Have

- Background with monitoring and BI/reporting for settlements and fees.

- Prior work building internal SDKs.


How We Work

- Remote-first with async-friendly collaboration; Europe time zones preferred for overlap.

Tech Stack:
- Backend: TypeScript / NodeJS • Cloudflare (Workers, D1, R2, Durable Objects) • Hono • Postgres

- Frontend: React • TypeScript • Material UI

- Infrastructure: Cloudflare, AWS (legacy hosting), Gitlab (source control, CI/CD, release management, task management)

- Legacy: Laravel PHP, Go
