Company mission
To provide a proven playbook that allows high-growth SaaS companies to leverage payments as a core part of their business model.
Role
Who you are
- 5+ years of experience building production backend services
- Strong experience with C# and the .NET ecosystem
- Strong experience in Payments, FinTech, or other high-volume transaction processing environments
- Experience designing and building RESTful and/or event-driven APIs
- Strong understanding of relational databases, data modelling, and distributed systems
- Experience building secure, scalable cloud-based applications
- Excellent problem-solving, communication, and collaboration skills
- Ability to provide technical leadership while remaining hands-on in development
What the job involves
- We are looking for a Senior Software Engineer, Backend to join our team and help build the backend of Payabli's interfaces and integrations that sit between complex financial infrastructure and the humans who use it every day – merchant dashboards, onboarding flow, embeddable components, and white-label experiences consumed by our platform partners and their end users
- In this hands-on role, you'll design and build the services that power intelligent payment routing, connector management, token intelligence, and platform configuration
- You'll work on complex, high-scale systems that enable merchants to optimize payment performance while building secure, extensible infrastructure for the future of payments
- You'll collaborate closely with Product, AI, and Engineering teams, mentor junior engineers, and play a key role in shaping the architecture of a platform used by substantial enterprise customers
- Design, build, and maintain scalable backend services using C# and .NET
- Develop the core infrastructure that powers payment routing, connector management, and platform configuration
- Design secure, extensible APIs that support both customer-facing applications, direct integrations and AI-powered workflows
- Build reliable, observable services that process high-volume payment transactions with performance and resilience in mind
- Contribute to platform architecture, engineering standards, and technical decision-making
- Continuously improve system performance, security, reliability, and developer experience
- Collaborate closely with other service owning teams to integrate via APIs and real-time data streams, ensuring seamless data flow across the stack & overall platform
- Raise the bar: Lead code reviews, champion backend standards, and drive architectural decisions that keep the codebase healthy as we scale
- Multiply the team: Mentor engineers around you and elevate backend engineering quality across the organization through pairing, documentation and leading by example
- Own the full lifecycle: Work across requirements, implementation, testing, and deployment. We don't throw things over the wall here
- Sweat the details: Optimize for performance, accessibility, and cross-browser compatibility
Our take
Though often overlooked as a necessity and functional aspect of doing business, Payabli is a software company that actually elevates what payments are capable of bringing to a company. Payabli’s platform aims to make payments not just a function that employees don’t think twice about, but something that can enhance their customers' experiences.
With an increasing number of companies migrating from legacy payment software to vertical SaaS (operationally specific) providers, Payabli is carving out a niche in the competitive space through simultaneous payout automation, stack optimisation, and customer payment services all on one platform.
Payabli’s focus on high-growth SaaS companies as its customers could be a slight gamble, given the turbulence in the sector, possibly leading to problems with customer retention. Payabli has not had any trouble so far, though, having tripled its growth in 2022 and benefiting from two rounds of funding within one year. It received further funding in 2025 and plans to use it to develop its products, particularly AI-driven personalisation experiences for customers.
