Senior Software Engineer - Product-Led Growth

• Drive end-to-end development of the backend services that power in-product growth experiences: eligibility, targeting, offer delivery, self-serve purchase, activation, and conversion tracking, owning the full lifecycle and iterating on measured outcomes.
• Build the shared infrastructure that makes the next experiment cheaper than the last: reusable targeting and eligibility services, campaign configuration, and a purchase flow that new offers plug into rather than rebuild.
• Build and evolve integrations with the systems those services depend on, consuming propensity scores, Toast IQ recommendations, and CMS-driven campaign controls, and connecting to billing, contracting, and provisioning systems so a restaurant can complete a purchase inside the product.
• Build LLM-powered experiences on Toast IQ, from prompt and tool design through evaluation and production monitoring.
• Design experimentation and attribution instrumentation so every launch has a clear measurement story, and use production data to kill or scale experiences quickly.
• Partner with product, design, marketing, sales, and data science to translate business goals like adoption and upsell targets into concrete, testable product changes.
• Contribute to technical design and architecture discussions, and help set engineering standards for a team that is growing.
• Mentor other engineers through code review, pairing, and technical guidance.

• 5+ years of software engineering experience building and maintaining production backend systems in Kotlin, Java, or another object-oriented language, with enough full-stack experience to ship web or native front-end changes when needed.
• Proven ability to own features end-to-end through design, launch, measurement, and iteration.
• Product-minded builder who is comfortable making product calls, launching, and iterating on what customers actually do, working across PM, design, and sales rather than executing tickets.
• Experience with experimentation, A/B testing, or growth engineering, and a working understanding of attribution: you can explain why a metric moved and whether to believe it.
• Experience building on LLMs or AI platforms, in production or in side projects. Interest in agents and tool use is a bonus.
• Experience building customer-facing features on top of data products such as scores, segments, or recommendations is a plus.
• Comfortable with ambiguity and with making tradeoffs between speed and scale.
• Proficient with AI tooling such as Claude, Cursor, and MCP servers.
