Sr. Software Engineer (AI)

Sr. AI Software Engineer The Emerging Team is focused on building AI Products for our product experience (PX) platform. We build from the ground up to explore, prototype, and ship AI‑native experiences that change how software teams understand and serve their users. This is not an AI layer added to an existing product; it is a deliberate bet on what product intelligence looks like next. The team operates with high autonomy, moves quickly, and builds products without clear precedents. As a Sr. AI Software Engineer, you will sit at the intersection of deep technical capability and strong product judgment. You will design and ship applied AI systems, including RAG pipelines, agentic workflows, and LLM‑powered features, from prototype through production. You will make principled technical decisions, evaluate model behavior rigorously, and communicate trade‑offs clearly to engineers and non‑engineers alike. This role is based in our New York office. What this looks like day‑to‑day Applied AI systems: Design and build AI systems including RAG pipelines, agentic workflows, and LLM‑powered features. You will take work from prototype through production and ensure it can hold up in real customer environments. Technical decision‑making: Make principled decisions on when to prompt, when to fine‑tune, and when to use a different tool entirely. You will explain these trade‑offs clearly so the team can move quickly without sacrificing quality. Model evaluation: Instrument and evaluate model outputs rigorously by defining evaluation frameworks and catching hallucinations early. You will implement guardrails that can withstand real‑world load and production use. MLOps ownership: Own model deployment, monitoring, latency optimisation, cost management, and reliability at scale. You will help ensure AI systems are observable, efficient, and dependable in production. Full‑stack product shipping: Contribute across the stack when needed because this team ships products, not just models. You will work across backend and frontend to get AI‑powered experiences in front of users. Product partnership: Partner closely with product and design to frame problems well before writing code. You will push back when the framing is wrong and help the team focus on what should be built, not just what can be built. Research and tooling awareness: Stay current on the research and tooling landscape, including transformers, diffusion architectures, orchestration frameworks, and emerging agent patterns. You will bring relevant advances back to the team and apply them thoughtfully. Who You Are Beyond the qualifications, we hire through a specific lens. These aren't buzzwords; they're the things we'll actually look for in how you talk about your work. You're a builder, not a maintainer. You're most energized when there isn't a clear path yet, and you get to define it. You don't wait for direction; you identify gaps, shape solutions, and drive them forward. At Pendo, great Sr. AI Software Engineers don't just follow instructions; they operate as strategic advisors, influencing decisions, guiding stakeholders, and elevating how we work. You're AI‑curious — genuinely. You're not using AI tools occasionally. You're rewiring how you work around them. You're faster, sharper, and more prolific because of it, and you bring that energy to everything — how you approach your work, how you prep, how you communicate, how you think. We want someone who sees AI as a multiplier, not a shortcut. Must‑haves Deep hands‑on experience building and shipping LLM‑powered systems, including retrieval‑augmented generation, tool use, and agent orchestration frameworks. Strong technical depth in system design, including choosing the right architecture, identifying failure modes early, and making trade‑offs that hold up across the product lifecycle. Experience owning technical quality beyond your own features, including setting standards, catching problems in review, and improving shared infrastructure and tooling. Strong command of model evaluation, including designing evaluation suites, reasoning about overfitting and bias‑variance trade‑offs, and systematically detecting and mitigating hallucinations. Solid understanding of modern model architectures, including transformers and diffusion models, with the judgment to decide when and how to apply them. Production MLOps experience, including model deployment, monitoring pipelines, and latency, cost, and reliability optimisation in a live environment. Strong full‑stack fundamentals with the ability to work across backend and frontend systems to ship complete, user‑facing AI products. Exceptional communication skills with the ability to explain complex technical decisions clearly to engineers, product managers, and executives. Demonstrated product thinking, including the ability to ask whether something should be built before deciding how to build it. Nice‑to‑haves Experience fine‑tuning foundation models and a clear point of view on when fine‑tuning outperforms prompting approaches. Familiarity with AI safety considerations, guardrail frameworks, and responsible deployment practices. Experience building agentic or multi‑step reasoning systems using tools such as LangChain, LlamaIndex, or custom orchestration frameworks. Background in a SaaS or product analytics environment where user behaviour data informs AI design. Prior experience contributing to or launching a net‑new team or product area.
