Job Title

Senior Implementation Engineer

What does a successful Senior Implementation Engineer do at Fiserv?

You will develop, manage, and showcase innovative solutions to complex business problems that leverage the Finxact Core APIs and technical features. With a focus on ensuring customer success, the Implementation Engineer’s primary role is to provide technical consulting to clients and serve as a subject matter expert on the Finxact Core APIs and integration points. In addition, the Implementation Engineer role encompasses all components of client implementations, training, overall product feedback and client support. When clients present vendors that are not already integrated to the Finxact core, you will provide consultative guidance on how the vendor can be integrated into the ecosystem. Most importantly though, you will consult the client on best practices regarding integration models, workflows and you will support the client’s users through onboarding to help them get the most out of the solution you helped design. The ideal candidate will have a background in financial software working with clients directly and with internal project team members.

What you will do:

Obtain and maintain an in-depth understanding of Finxact’s technology and its underlying architecture
Work with clients to solve complex business problems, trouble shooting, and using the Finxact Core and its surrounds
Communicate complex technical concepts to a variety of audiences
Interface directly with ecosystem partners, clients, and internal teams to promote the adoption of our product
Support the technical design process by participating in the analysis of technical application and client ecosystem requirements
Assist in analysis that will identify requirements related to people, processes, and technology.
Develop and code core functionality and interfaces for our solution
Participate in execution and documentation of tests
Assist in the deployment process for client implementations

What you will need to have:

6+ years professional experience in API and software development
2+ years of experience programming functional, imperative or object-oriented languages
Bachelor’s degree in computer science, engineering, or a related field, or an equivalent combination of education, work, and military experience

What would be great to have:

Financial industry experience and knowledge of Golang programming
Stellar communication, collaboration, problem-solving and accountability skills

Perks at Work:

We’re #FiservProud of our commitment to your overall well-being with a growing offering of physical, mental, emotional, and financial benefits from day one.
Maintain a healthy work-life balance with paid holidays, generous time off policies, including Recharge & Refuel time for qualifying associates, and free counseling through our EAP.
Plan for your future with competitive salaries, the Fiserv 401(k) Savings Plan, and our Employee Stock Purchase Plan.
Recognize and be recognized by colleagues with our Living Proof program where you can exchange points for a variety of rewards.
Prioritize your health with a variety of medical, dental, vision, life and disability insurance options and a range of well-being resources through our Fuel Your Life program.
Advance your career with training, development, certification, and internal mobility opportunities.
Join Employee Resource Groups that promote our diverse and inclusive culture where associates can share perspectives, exchange ideas, and elevate careers.
