Senior Staff Microservices Engineer - API Banking & Integration

Ignite Banking

About The Position

Ignite Banking is seeking a Senior Microservices Engineer with deep experience in API development, APIGEE, and IBM DataPower to support the delivery of next-generation open finance and digital banking platforms. This role sits within our API Banking & Integrations team, working directly with client architecture and engineering teams to design and build modern, scalable integration solutions. This is a hands-on development lead role — you will be expected to actively design, build, and deliver microservices and APIs, while also guiding technical direction and setting standards across engagements. This is not a purely oversight or architecture role; success in this position requires strong engineering execution paired with the ability to lead by example. This is not a traditional development role — this individual will operate as a front-line consultant (“tip of the spear”), leading early-stage technical execution across multiple engagements. You will be expected to bring both strong engineering capability and a consultative mindset, helping clients navigate complex transformation initiatives. This role is remote, however, strong preference will be given to candidates located in Charlotte or Raleigh, NC, who are open to working onsite with clients several days per week as engagement needs require.

Requirements

5+ years of experience building Java-based microservices (Spring Boot)
Strong experience designing and implementing REST APIs
Hands-on experience with APIGEE (proxies, policies, API products, developer apps, security)
Experience with IBM DataPower in API gateway or integration roles
Strong understanding of API design, JSON/XML, and service orchestration
Experience deploying services in Azure environments
Working knowledge of Kubernetes (AKS) and containerized applications
Familiarity with secure service-to-service communication (OAuth2, mTLS)
Prior experience working in a consulting or professional services environment
Ability to operate independently in client environments with limited direction
Strong communication skills with the ability to engage both technical and business stakeholders
Comfortable leading early-stage technical work and shaping solution direction
Experience working within banking or financial services environments
Familiarity with digital banking platforms, core banking integrations, or open banking architectures
Understanding of enterprise integration patterns and modernization strategies

Experience modernizing legacy integration platforms into API-first architectures
Exposure to event-driven or distributed system design patterns
Familiarity with observability tools (App Insights, Splunk, Dynatrace, etc.)
