Job Title

Staff Applied AI Engineer

About Your Role

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

What you’ll do:

• Own and drive technical architecture, design, implementation, testing, and deployment.
• Contribute towards AI Strategy & Roadmap, and deliver the applied AI portfolio.
• Design tool layer for agents writing to inventory — change proposals, permissions, rollback, audit.
• Build the retrieval layer (RAG) — agent output grounded in merchant data, current as it changes.
• Define behavioral contracts, build the evals that prove them, and ship on evidence, not demos.
• Engineer multimodal ingestion — photos, PDFs, spreadsheets into canonical data, reviewed where required.
• Build the decision layer on model output: recommendations merchants understand, trust, and act on.
• Instrument, operate, and stay on call for what you ship — tracing, cost budgets, live quality.
• Extend the shared multi-agent framework, contribute upstream, and use coding agents well.
• Coach and mentor engineers, growing their skills and careers in applied AI.
• Establish the patterns, guardrails, and components peers adopt.
• Responsibilities listed are not intended to be all-inclusive and may be modified as necessary.

Experience you'll need to have:

• Education: BS in computer science, engineering, math, physics, or equivalent practical experience.
• Senior Technical Leadership: 10+ years in software development, 3+ leading complex production systems.
• Engineering Foundations: Algorithms, data structures, Kubernetes, REST APIs, microservices.
• Stack: Python and a JVM language (Java, Kotlin, Scala); MySQL, MongoDB, and vector databases.
• Problem Solving: Analytical skills to root-cause systems that fail differently on identical input.
• Production Agent Ownership: An LLM system that writes to a system of record, with real users.
• Evaluation-Driven Development: Specs and contracts, evals that gate releases, statistical judgment.
• AI Systems Operations: Tracing, live quality monitoring, latency/cost budgets, regression detection.
• Risk Judgment: Blast radius on writes to a system of record; prompt injection; security and privacy.
• Agentic Coding Fluency: Steering coding agents with specs and verifiers; knowing when to intervene.
• Product Judgment: Turning vague merchant needs into a spec — what to cut, MVP or prove it first..
• Cross-Team Influence: The technical case to peers, the business case beyond engineering.

Experience that would be great to have:

• Model Platforms: Gemini and Vertex AI, or production work on Claude, GPT, or Llama.
• Multi-Agent Orchestration: Coordination, handoff, failure containment across agents; MCP.
• Retrieval Depth: RAG over structured records rather than documents, including when not to use it.
• Document AI: Structured extraction from images and PDFs at production quality..
• Frameworks & Practices: Spring Boot; agent frameworks such as LangChain or LlamaIndex; BDD/TDD
• Domain: POS, restaurant, or retail systems; menu or catalog data models.
• Advanced Degree: Master's degree in Computer Science or a related 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
