WEX
About the Team/Role
As a
Staff Software Engineer
on the DCA team, you will be a key technical leader responsible for the stability, performance, and future architecture of our mission-critical
Digital Credit Application (DCA)
platform.
This role requires deep technical ownership, focusing on the backend services and complex transaction flows required before a credit decision (adjudication). You will be a vital link between Product and Engineering, actively
managing stakeholder relationships
by translating intricate business requirements into scalable, secure, and robust system designs.
Your mission is to guide the team toward a more
flexible microservice architecture
to address current platform limitations. You will drive solutions to persistent problems like data transaction conflicts, integration complexities with external fraud APIs (Plaid, LexisNexis), and operational challenges stemming from the current technology stack.
This is a hands-on position where you will set technical standards, provide critical
mentorship to junior engineers , and solve complex, large-scale problems that directly impact our core business success across
North America Mobility (NAM), Over-the-Road (OTR),
and
Customer Payment Solutions (CPS) .
How you’ll make an impact
Lead the design, architecture, and implementation of highly available and resilient microservices using Java and the Spring ecosystem.
Drive technical roadmaps, project plans, and architectural decisions, balancing rapid delivery with long-term platform stability.
Be responsible for critical non-functional requirements, including system performance, observability, security, and scalability under high load.
Define and advocate for engineering best practices, including code quality standards, comprehensive testing strategies, and efficient code review processes.
Partner closely with product management and front-end teams to design clean, effective, and robust APIs (REST/gRPC).
Advise senior leadership on complex technical trade-offs and lead technical initiatives across organizational boundaries, driving consensus and adoption.
Provide technical mentorship and guidance to mid-level and senior engineers, fostering a culture of high engineering standards.
Experience you’ll bring
A highly skilled, innovative, and experienced Software Engineer capable of acting and delivering to complex business needs.
Have
10+ years
of progressive software design and development experience at scale, with significant experience in a technical leadership or staff-level role.
Deep expertise
in
Java
and the
Spring ecosystem (Spring Boot, Spring Data)
.
Proven experience designing and operating
distributed systems
and
microservices architectures
in a cloud environment (AWS, Azure, or GCP).
Mandatory experience with high-volume
data modeling, transactional integrity, and database technologies
(both relational like PostgreSQL and NoSQL like Cassandra/MongoDB).
Strong practical experience with
event-driven architectures
and messaging systems (e.g.,
Kafka
or RabbitMQ).
Experience
working with
Service Mesh technologies like Istio
for traffic management, security (mTLS), and resiliency patterns.
Demonstrated commitment to engineering quality, including deep experience with
Test-Driven Development (TDD)
and designing robust
regression testing
strategies.
Expert knowledge of
CI/CD pipelines
, deployment automation, and modern observability tools (e.g., Prometheus, Grafana, Jaeger).
Excellent analytical skills and capability in identifying and resolving complex, cross-functional problems.
Strong written and verbal communication skills, able to present complex technical concepts clearly.
Bachelor's degree in Computer Science or a related field.
The base pay range represents the anticipated low and high end of the pay range for this position. Actual pay rates will vary and will be based on various factors, such as your qualifications, skills, competencies, and proficiency for the role. Base pay is one component of WEX's total compensation package. Most sales positions are eligible for commission under the terms of an applicable plan.
