Senior Software Engineer (Product-Led Growth)

• The Product-Led Growth team builds the in-product experiences that help restaurants discover, try, buy, and adopt the Toast products they need
• We own the services and surfaces that decide which restaurants see which offers, carry them through purchase and activation inside the product, and tell us whether it worked
• This is measurable, revenue-attached work
• Every experience we ship has a conversion metric behind it, and we know within weeks whether it worked
• We’re a small team with a large surface area, and we’re early in turning PLG from a set of hand-built campaigns into a platform: shared targeting, offer delivery, purchase, and measurement services that let us launch a new experiment in days instead of weeks
• You’ll ship experiments into production, read the results, and decide what comes next, and you’ll build the shared services that make each launch faster than the last
• You’ll work with product, marketing, sales operations, and data science to turn a hypothesis about customer behavior into a targeted in-product experience, then prove or disprove it with data
• 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
