Job description

Paydock is a fast-scaling payments orchestration platform empowering businesses to take control of their payment infrastructure. We're passionate about improving the way people experience payments and are dedicated to building innovative, secure, and scalable systems.

Role Summary

We are looking for a full-stack engineer to join our engineering team. You will be joining a team responsible for (not limited to) maintaining and building api-gateways, comprehensive authentication and authorization solutions and user and partner onboarding APIs. This role blends software engineering, research and app security.

You are a versatile Senior Full-Stack Engineer wanting to help us build our next generation payment orchestration platform. You should be passionate about creating robust, secure, and scalable systems, particularly within the domain of identity and access management.

Key Responsibilities

• Design and build core services: Own end-to-end feature development on microservices that are on Paydock’s critical-path.
• Secure the platform: Architect, implement, and maintain our authentication and authorization solutions, ensuring best-in-class security for all user and partner interactions.
• Identity management: Develop and enhance the organization, brand, merchant, user, onboarding and offboarding APIs and underlying systems
• Full-Stack Development: Contribute across the entire stack, from database design and back-end logic with occasional but necessary contributions to front-end development of internal and customer-facing management dashboards.
• Research and Security: Responds to identified security vulnerabilities and keeping up to date with authentication and authorization standards.
• Be a role-model: Mentor all engineers, participate in code reviews, and drive technical discussions to ensure high quality and architectural excellence across the team.
• Collaborate: Partner with Product Managers and other engineering teams to define specifications and deliver features that meet both performance and security requirements.

What We’re Looking For

• Five or more years working as an engineer in SaaS or PaaS companies.
• Production-grade experience in NestJS and Angular
• Experience implementing comprehensive authentication and authorization solutions (e.g., OAuth 2.0, OIDC, SSO/SAML, RBAC, ABAC, ReBAC). Our system is maintained in-house and this knowledge is critical. As you will be one of the main contributors to a fresh implementation of our identity access management solution.
• Experience with long-running asynchronous processes. Your team is often responsible for creating flows that allow financial-institutions to seamlessly onboard and offboard their customers and resources into our platform.
• Communication skills and the ability to work effectively in an asynchronous, research-driven engineering environment. We count on everyone to contribute to documentations, RFCs and, most importantly identify roadblocks as they arise to avoid surprises during delivery.

Nice to Have

• Familiarity with cloud platforms (e.g., AWS, Azure, GCP) and experience leveraging their managed services from an engineering perspective. We have a dedicated DevOps team that deals with infrastructure implementation and integration.
• Interest in Application Security and secure coding practices. We have a dedicated AppSec team to answer your questions and lead you towards success.
• Contributions to open-source projects or writing technical content related to security, APIs, or full-stack architecture.
• Previous work experience with Relationship Based Access Control (ReBac) authorization models (e.g., Google Zanzibar, Open FGA, etc.)

Why Join Paydock?

• Work with a passionate, remote-first team that's reshaping payments.
• Opportunity to lead and define AI use cases at a scaling fintech company.
• Flat structure, collaborative culture, and the chance to have a real impact.
• Competitive compensation and flexibility.
