Job Title

About your role:

Clover, a Fiserv company, is building AI that acts on live merchant data at enterprise scale. In this role, you will be a hands-on technical leader for applied AI on the Point of Sale platform. You will define the architecture for AI across inventory, menu, and ordering, building the systems that modernize how merchants run their business.

What you’ll do:

• Own and drive end-to-end technical architecture, design, implementation, testing, and deployment across the applied AI portfolio while contributing to the overall AI strategy and roadmap.
• Design safe tool layers (change proposals, permissions, rollback, audit) and advanced retrieval layers (RAG) that keep agent outputs grounded in real-time merchant data.
• Define behavioral contracts, build eval harnesses to gate releases on empirical evidence, and engineer decision layers for trustworthy, actionable merchant recommendations.
• Develop multimodal ingestion pipelines to convert photos, PDFs, and spreadsheets into canonical data with merchant review workflows where required.
• Instrument, operate, and maintain on-call ownership for production systems, managing tracing, cost budgets, and live quality monitoring.
• Extend the shared multi-agent framework, contribute upstream, leverage agentic coding tools, mentor engineers, and establish reusable AI patterns and guardrails across teams.
• Responsibilities listed are not intended to be all-inclusive and may be modified as necessary.

Experience you’ll need to have:

• Bachelor's degree in Computer Science, Engineering, Mathematics, Physics, or equivalent practical experience.
• 10+ years in professional software development, including 3+ years leading complex production systems through to deployment.
• Strong software engineering foundations in algorithms, data structures, Kubernetes, REST APIs, and microservices.
• Dual-language fluency in Python and a JVM language (Java, Kotlin, or Scala), alongside experience with SQL (MySQL), NoSQL (MongoDB), and vector databases.
• Strong analytical problem-solving skills to perform root-cause analysis on non-deterministic systems.
• Production ownership of action-oriented LLM systems writing to a system of record with real users.
• Hands-on expertise in evaluation-driven development (behavioral contracts, eval-gated releases) and live AI systems operations (tracing, rate limits, latency/cost budgets, live monitoring).
• Strong risk judgment regarding blast radius, prompt injection, and security/privacy when AI writes to persistent databases.
• Demonstrated fluency with agentic coding workflows (steering tools with specs and verifiers), strong product judgment, and cross-team influence.

Experience that would be great to have:

• Production experience with Gemini and Vertex AI, or other model families (Claude, GPT, Llama).
• Multi-agent orchestration experience (coordination, handoffs, failure containment, MCP).
• Advanced retrieval depth (RAG over structured records) and Document AI (extraction from PDFs/images).
• Experience with Spring Boot, agent frameworks (LangChain, LlamaIndex), and BDD/TDD development practices.
• Domain knowledge in POS, restaurant, or retail systems, along with menu or catalog data models.
• Master's degree in Computer Science or a related technical discipline.

How you’ll work:

• This role is on-site Monday through Friday. Fiserv considers in-person collaboration to be an essential part of this role as in-person office experiences help you with your overall onboarding experience and leads to stronger productivity.
• This role requires being on-call during non-standard and/or overnight hours on a rotational basis.
• This role requires use of a computer and audio equipment.

Benefits at Fiserv:

• Fuel Your Life program to support your physical, financial, social, and emotional well-being
• Paid holidays and generous time away policies
• No-cost mental health support through Employee Assistance Programs
• Living Proof program to recognize your peers’ extra effort with points redeemable for rewards
• Eight Employee Resource Groups to foster a collaborative culture and expand your network
• ·Unparalleled professional growth with training, development, and internal mobility opportunities
• Medical, dental, vision, life, and disability insurance options available from day one
• Retirement planning and discounted shares with the Employee Stock Purchase Plan
• Tuition assistance and reimbursement program
• Paid parental, caregiver, and military leave
