Funding Engineering Manager

About the Team/Role

You'll lead a dynamic engineering team in our modern payments platform, currently powering corporate payments with plans to expand across all lines of business. Your team builds on an event-driven, microservices architecture in Kubernetes, using Terraform, Kafka, and CI/CD to enable true continuous delivery. You embrace AI-assisted engineering to improve quality, speed, and developer experience, and you guide teams to use these tools responsibly and securely.

As a servant leader who earns trust through technical credibility and genuine investment in your team's growth, you'll set clear technical direction, stay hands-on with the code, and foster an accountable, growth-oriented culture.

You'll tackle complex engineering challenges at scale, processing millions of transactions daily on a cloud-native platform that meets aggressive uptime SLAs. In partnership with Product, you'll align on outcomes and use delivery and reliability metrics to reduce friction and invest in resilient, observable systems. Your work directly impacts WEX's ability to process payments reliably and securely at scale, with opportunities to shape the future architecture of our payments ecosystem.

Who This Role Is For

This role demands genuine strength across both technical delivery and people leadership.

You'll write production code, lead architectural decisions, AND build high-performing teams. If you've moved away from hands-on engineering or prefer to delegate technical decisions entirely, this isn't the right fit. Similarly, if people leadership feels like overhead rather than core to your impact, you'll struggle here.

We're looking for someone who:

Gets energy from both solving hard technical problems AND watching their people grow

Can mass context-switch between a gnarly production issue and a difficult 1:1 conversation

Sees code review as a mentoring opportunity, not a bottleneck to clear

Believes the best technical decisions come from empowered teams, not top-down mandates

How You'll Make an Impact

Technical Leadership

Spend meaningful time hands-on each week - writing production code, pairing on complex problems, and leading design sessions

Be the person your team comes to for hard technical calls - you don't defer every decision to a tech lead

Own architectural direction and technical roadmap for your team's services

Model engineering excellence through deep, constructive code reviews that teach as well as critique

Champion responsible, secure adoption of AI tools across the SDLC to accelerate delivery and improve quality

People Leadership

Lead with a servant leadership style - you're there to remove obstacles, provide context, and help your team succeed, not to direct every decision

Build a safe, accountable culture where high standards and psychological safety coexist

Mentor and grow engineers through regular 1:1s, actionable feedback, and deliberate stretch opportunities

Enable autonomy by clarifying intent and guardrails, then trusting your team to make decisions

Have the hard conversations when needed - performance, behaviour, career pivots — with directness and empathy

Delivery & Operations

Deliver reliably, using meaningful metrics like lead time, change failure rate, and MTTR to drive improvement

Remove friction by unblocking work, reducing tech debt, and streamlining processes to maintain flow

Own complex technical, delivery, and operational problems end to end

Promote resilient architecture and operational excellence across services

Represent the team with stakeholders to reduce churn, align priorities, and amplify impact

Non-Negotiable Requirements

These aren't "nice to haves" — we assess all of them equally:

You can write, debug, and review production C#/.NET code today — not five years ago

You've built and led teams where people grew, stayed, and delivered — you can talk about specific individuals and how you helped them develop

You've owned architectural decisions for distributed systems and can defend them at a whiteboard, including the trade-offs you made

You've shipped software using CI/CD, IaC, and modern DevOps practices — not just approved others doing it

You actively use AI-assisted development tools and can coach others to get real value from them without overreliance

Experience You'll Bring

2+ years leading software engineering teams

10+ years of software development experience

Track record of building positive team cultures that balance high expectations with support and growth

Deep expertise in modern software engineering practices, cloud platforms, and DevOps approaches including test and deployment automation

Strong understanding of microservice architectures, distributed systems, and building data-intensive applications at scale

Excellent stakeholder management and communication skills

Experience with financial or payment systems (preferred)

Technology Stack

You'll work with (and should have experience in most of):

.NET/C# and TypeScript

Cloud-native development: Kubernetes, Terraform, Terragrunt, containerisation

Event streaming with Kafka

Modern frontend technologies (Angular)

CI/CD pipelines and infrastructure as code

Database technologies and data management practices

AI-assisted developer tools and LLM-based services

What to Expect in Our Process

We assess technical capability and leadership equally — strength in one doesn't compensate for weakness in the other.

Technical assessment: You'll complete a hands-on coding exercise and walk us through system design decisions you've made, including trade-offs and what you'd do differently

Leadership scenarios: We'll discuss real situations from your experience — how you've grown people, handled performance issues, navigated conflict, and built culture

Values alignment: We'll explore how you think about servant leadership, autonomy, and building inclusive teams

What You'll Get

Scope that matters — your team's work directly impacts payment processing at scale

Autonomy to shape your team's engineering practices and culture

The opportunity to stay genuinely hands-on while growing your impact through mentoring, hiring, and platform-wide influence

An inclusive, high-expectations environment where craft is valued

Access to the latest tech and AI tooling
