About The Team/Role
You'll join a high-performing engineering team building our modern payments platform,
currently powering corporate payments with plans to expand across all lines of business.
You'll work on an event-driven, microservices architecture in Kubernetes, using Terraform,
Kafka, and CI/CD to enable true continuous delivery. You'll embrace AI-assisted engineering
to improve quality, speed, and your own developer experience.
As a mid-level engineer, you'll work on meaningful features, ship production code regularly,
and grow your craft alongside experienced engineers. You'll contribute to technical
discussions, take ownership of well-defined pieces of work, and learn how to design and
operate systems that matter. Your work directly impacts WEX's ability to process payments
reliably and securely at scale.
Who This Role Is For
This role is for engineers who are past the early-career stage and ready to take on real
ownership, but still want to learn from people further along the path.
We're looking for someone who
- Takes ownership of the problems they're given and sees them through
- Writes clean, testable code and cares about doing things properly
- Is comfortable across the stack and wants to deepen in backend systems
- Communicates clearly and collaborates well with product and other engineers
- Wants to keep learning and welcomes feedback on their work
How You'll Make an Impact
Technical Delivery
- Build and ship features end-to-end with guidance on the harder calls
- Write production-quality C#/.NET code with appropriate test coverage
- Contribute to services that process payments reliably at scale
- Participate in architectural discussions and learn how technical decisions are made
- Use AI-assisted development tools effectively to accelerate your work
Quality & Operations
- Own the quality of what you ship, write tests, monitor production, fix issues
- Participate in code reviews that improve the codebase and help you grow
- Identify tech debt and improvement opportunities in your area
- Support operational excellence through observability, alerting, and incident response
Collaboration & Growth
- Pair with senior engineers and share what you learn with peers
- Work closely with Product to understand customer problems and help shape
solutions
- Communicate technical concepts clearly to both technical and non-technical
audiences
- Continuously improve your craft and stay current with modern engineering practices
Non-Negotiable Requirements
- You write clean, well-tested C#/.NET code, this is your primary language
- You've worked on distributed systems or microservices in production
- You have a working understanding of event-driven architectures and messaging
patterns
- You've worked with CI/CD pipelines and understand modern DevOps practices
- You take ownership, you don't just write code and throw it over the wall
Experience You'll Bring
- Around 2 to 5 years of software development experience as a signal, not a hard rule
- Solid experience with .NET/C# in a production environment
- Exposure to cloud-native development (Kubernetes, containerisation, infrastructure
as code)
- Some familiarity with event streaming, distributed systems, or data-intensive
applications
- Experience with modern frontend technologies (Angular, TypeScript) is a plus
- Financial services or payments experience is welcome but not required
Technology Stack
You'll work with (and should have experience in some of)
- .NET/C# and TypeScript
- Angular
- AWS
- PostgreSQL
- Kubernetes, Terraform, Terragrunt, containerisation
- Event streaming with Kafka
- CI/CD pipelines and infrastructure as code
- AI-assisted developer tools
- and more. We're not short on interesting tech to work with.
What You'll Get
- Work on systems that process real payments at scale, your code matters
- A team that values quality, ownership, and continuous improvement
- Opportunity to work with modern tech and grow into deeper technical work
- Autonomy to solve problems your way, with support when you need it
- An inclusive environment where your ideas are heard
