If you’re looking to make an impact with heart and hustle, SpotOn is the place for you. (REMOTE FRIENDLY) ABOUT THE ACCELERATE TEAM The Accelerate team is a new 5-person engineering team with a singular mission: prove that AI-native engineering practices can fundamentally change how a fintech engineering org builds software - then make that the new standard. The team has direct VP sponsorship, mission & charter, and three defined projects with hard deadlines. We're hiring a Staff/Principal IC who has already demonstrated AI-assisted engineering at scale. This is not an "AI-curious" role. You write code with AI every day. You've built agents that do real work. You have strong, experience-backed opinions on which models to use for what, where agents fail, and how to build guardrails that actually hold. You've seen what works in production and you're impatient to do it at scale. You will be the most technically senior AI practitioner on this team - the person everyone looks to for "how do we actually build this." You don't manage the team. You drive the architecture, build the hardest parts, and set the technical standard. THE ROLE: TECHNICAL LEAD, NOT MANAGER This isn't a "set up some CI/CD and plug in Copilot" role. You are the person who architects the systems that change how SpotOn engineers build software. You will: Be the AI engineering technical authority. You set the technical standard for how AI is used in code generation, review, testing, and task automation. You don't just implement tools - you design the systems, workflows, and guardrails that make AI-assisted development safe, measurable, and scalable in a PCI-regulated payments environment. The team lead sets priorities; you set the technical direction. Drive the architecture and implementation of three concurrent projects: - Automated PR Review - A risk-tiered AI review pipeline where AI handles first-pass review on every PR, with an escalation framework you design that determines when human review is mandatory (payment logic, PCI-scoped code, compliance paths) versus when AI approval is sufficient. You define the criteria. You tune the thresholds. You prove it works. - Android and API Test Automation - A fully automated test harness for our Android-native POS and KDS products: virtual device provisioning, test execution, teardown, AI-assisted failure analysis - replacing multi-day manual QA cycles with sub-30-minute automated runs. - AI Agent Swarms - A multi-agent pipeline that takes a PRD and produces a tested, reviewed pull request for tier 1-3 engineering work (nits, bugs, small features). You design the agent orchestration - planner, coder, tester, reviewer - and the blast-radius controls that keep it safe in fintech. Evangelize by shipping, not by presenting. Your most persuasive argument is a working system, not a slide deck. You demo to engineering leads every two weeks with real metrics. You turn skeptics into adopters by showing them their own time savings. Measure everything. You define the metrics framework: developer hours recovered, cycle time compression, quality ratios, cost per deployment. You report to the CTO monthly with quantified value delivered.
