About the role:  Forter is looking for a Senior Software Engineer to join a strong and dynamic AI Engineering team . We are the focal point for AI initiatives in Forter, striving to constantly bring innovation and leverage AI capabilities across all company teams and products. Today, AI is central to how Forter operates, across the entire organization. It allows us to move fast and release features at a rapid pace, empowers non-technical Forterians to utilize AI tools for increased efficiency, and provides the backdrop for much of the innovation currently occurring in the company. If this kind of working environment sounds exciting to you, if you understand that Engineering is about building the most effective and elegant solution within a given set of constraints - consider applying for this position. Why should you join us? This is a great opportunity to be at the cutting edge of the AI revolution, helping to shape and build the AI platform for the future. Together, we’ll build infrastructure for autonomous and interactive agents, enact AI guardrails and evaluation frameworks to ensure performance and safety, and implement state-of-the-art AI and Agentic patterns. This role presents a unique opportunity to enter the AI domain. For those with some experience in AI infrastructure, it offers the chance to grow within a team that is evolving Forter from the AI experimentation phase to building and leveraging AI-powered products. What you will be doing: Design, build, and maintain reusable AI capabilities - including models, tools, APIs, and platforms that power both internal and customer-facing solutions. Develop and maintain our internal MCP server that easily and securely exposes Forter’s vast data stores to AI agents. Create and implement robust evaluation frameworks and AI guardrails to safeguard Forter’s value and ensure model reliability. Establish deep expertise and sustainable AI engineering practices. Promote AI readiness and track adoption across the company to build lasting impact. Build and optimize RAG (Retrieval-Augmented Generation) systems. Take full ownership of projects: from gathering requirements from non-technical internal users to development, deployment, and operation. Act as a consultant and advocate for AI engineering, helping other teams leverage the platforms and tools you build. Partner with teams across Forter to accelerate AI adoption and productization efforts.   Who are you? 5+ years of strong backend and server-side development experience, building complex, highly scalable systems. Proven experience with at least one general-purpose language (preferably Python, but not a must). Strong product management skills, with the ability to gather and refine requirements from non-technical internal users. A strong sense of ownership, with some DevOps experience and a willingness to develop, deploy, and run projects end-to-end. Solid understanding of GenAI, LLMs and foundation models. Strong familiarity with AI coding tools like Claude Code, Github Copilot, Cursor, or similar. Hands-on experience with building AI-driven workflows, agentic frameworks, evals, RAGs, MCPs, skills, etc. Experience working with public clouds (AWS / GCP / Azure). Fluent in written and spoken English. About Us: Commerce is evolving faster than the systems built to support it. Agentic AI is redrawing how people buy. Customer expectations have a new ceiling. And bad actors are evolving alongside every advancement.  Forter was built to meet this moment — and stay ahead of it. We are a human-first, AI-built company. Our technology analyzes patterns across a network of over 2 billion shoppers, delivering identity intelligence across the entire commerce journey — from sign-up to checkout to returns — that protects revenue and unlocks great customer experiences simultaneously. With Forter, businesses know who to trust, whether it’s humans or the agents shopping for them. The result: zero friction for the customers who matter. No revenue left behind. The world's most trusted brands — Nordstrom, Instacart, Priceline, Adobe, ASOS, and eBay among them — rely on Forter to get this right. Since 2013, we've raised $525M from investors including Tiger Global, Bessemer, Sequoia Capital, and Salesforce Ventures, and today we power commerce decisions for nearly 1 million businesses globally. We're more than fraud, payments and orchestration – we make trust a competitive advantage. Trust is backed by data –  Forter is a recipient of over 10 workplace and innovation awards, including:  Great Place to Work Certification (2021, 2022, 2023, 2024, 2025 ) Fortune’s Best Workplaces in NYC (2022, 2023, 2024 and 2025 ) Forbes Cloud 100 (2021, 2022, 2023, 2024 and 2025 ) Anti-Fraud Solution of the Year at the Payments Awards ( 2024 ) Life as a Forterian: Forterians are, genuinely, some of the best people you'll work with. Smart, curious, and deeply good humans who care about the work and each other. That's not an accident — it's something we've been intentional about since day one, and it's the thing people mention most when they talk about why they stay. When you're surrounded by people like this, doing work that actually matters, it changes what a job can feel like. Forter was built on a simple but powerful conviction: when AI does its job, humans can do theirs better. That philosophy shapes our products and shapes how we work. AI is core to our workflows — not as a shortcut, but as a force multiplier that gives Forterians the space to focus their energy where human judgment is irreplaceable. We're a global team of 500+ people, with regional headquarters in New York, Tel Aviv, London, and Singapore, and employee presence across the US, Canada, Germany, France, Japan, China, and Australia. Our teams are cross-functional by design, and the work you do here is visible, consequential, and connected to the outcomes that matter. You'll have real ownership here and proximity to decisions. And we back that with investment in your growth — RSU offerings, L&D programs built around AI tools, and a culture of recognition rooted in our 4.5 day weeks (aka Forter’s Appreciation Fridays and Sundays). From team outings to local cultural celebrations, we mark the moments that matter — wherever you are in the world. We don't want Forter to be just another job. We want it to be the place you build. If you're ready to work on a problem that sits at the intersection of AI, commerce, and human trust, this is it.
