Senior Software Engineer in Whitehall

Tipalti is building an AI-native product to help with end of month accounts. The information below covers the role requirements, expected candidate experience, and accompanying qualifications. Today, closing the books takes 5–6 accountants roughly 14 working days, chasing down discrepancies across spreadsheets, payroll systems, invoices, and disconnected data sources. This product is being built from scratch to automate large parts of that reconciliation work using AI, not as an add-on to an existing process, but as the product's core design principle from day one. The team operates with very few conventional handoffs between product, design, engineering, and customer-facing work. You'll be expected to run it that way too: make decisions with incomplete information, move fast, and treat mistakes as inputs rather than setbacks.

Why join Tipalti? Tipalti is the AI-powered platform for finance automation, elevating how finance teams operate in the global economy. We empower our customers to scale faster and smarter by removing the complexities of doing global business and accelerating their finance operations efficiency. Our platform provides a comprehensive suite of finance automation solutions designed for mid-market businesses across accounts payable, global payouts, procurement, employee expenses, corporate cards, supplier management, tax compliance, and treasury. Tipalti partners with leading financial institutions such as Citi, Wells Fargo, J.P. Morgan, and Visa, enabling over 5,000 global companies to efficiently and securely pay millions of suppliers and payees across 200+ countries and territories, in 120 currencies.

At Tipalti, we pride ourselves on our collaborative culture, the quality of our product and the capabilities of our people. Tipaltians are passionate about the work they do, and keen to get the job done. Tipalti offers competitive benefits, a flexible workplace, and an environment where diverse individuals can thrive and make an impact. Our culture ensures everyone checks their egos at the door and stands ready to reach for success together.

The Role: As a Senior AI Software Engineer, you'll play a key role in launching and scaling a new AI-native product area. You'll work in a cross-functional squad to:

• Turn ambiguous problems into well-designed, scalable AI-powered systems
• Build high-quality, LLM-driven features end-to-end — from prototype to production
• Design and integrate agentic workflows, retrieval systems, and model-orchestration pipelines
• Deliver AI solutions that make a measurable difference for customers

You'll contribute across the stack, with a strong focus on backend APIs and services that power AI/LLM-driven functionality in expenses and procurement.

What You'll Be Doing:

• Design, build, and ship end-to-end AI-powered features for a new product
• Collaborate closely with Product Managers and Designers to shape technical and AI strategy
• Develop and evolve scalable backend APIs, microservices, and LLM-orchestration layers
• Build robust evaluation frameworks to test and improve model performance and reliability
• Write clean, well-tested, maintainable code — including around probabilistic/AI components
• Participate in code reviews, architecture discussions, and pair programming
• Mentor junior engineers and help raise engineering and AI-quality standards
• Contribute to a team culture of continuous learning and shared success

About You: You might be a great fit if:

• You take pride in building reliable, high-quality AI-powered software
• You think in systems and care about long-term maintainability — including of AI/LLM pipelines
• You've built or shipped features using LLMs, agents, embeddings, or similar AI tooling
• You enjoy collaborating and shaping ideas early, especially where the 'right approach' isn't obvious yet
• You're comfortable mentoring others and sharing knowledge
• You thrive in environments where you have ownership and influence
• You're adaptable and excited to learn new AI techniques, models, and domains

Our Mission: Our mission is to elevate how finance teams operate in the global economy.
