Full Stack Engineer IAM in Manchester

About Paydock

Paydock is a fast-scaling payments orchestration platform empowering businesses to take control of their payment infrastructure. We are 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 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: Respond to identified security vulnerabilities and keep 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.
• 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 documentation, 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.
• Interest in Application Security and secure coding practices.
• 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.
