Senior Product Engineer

About Us We’re building toward the AI-native back-office for small businesses, autonomous agents that do the work, paired with expert-backed service and a clean, modern surface owners actually want to use. Our AI Ledger, autonomous bookkeeping that closes books in hours instead of weeks, with reporting and P&L statements that are accurate, current, and trustworthy. It's the most strategic bet on the roadmap. We’re a lean, high-trust team. That means less process, fewer layers, and more ownership. Engineers here don’t just ship code; they shape the product, influence decisions, and see their work directly impact customers. The Opportunity We're looking for a Senior Product Engineer who thrives in ambiguity, ships fast, cares deeply about building reliable, well-crafted systems, and works AI-first by default. You’ll work across the stack to design and build core financial workflows, from backend systems and APIs to the user-facing experiences that make them usable. You’ll play a key role in shaping our architecture, product direction, and how we operate as an engineering team. You’ll ship faster than a 2025 engineer, by steering AI to do most of the implementation while you focus on judgment, decomposition, and verification. You know what good looks like! This is a hands-on role with real ownership with direct report to the CTO. You’ll be trusted to make decisions, not just execute. What You’ll Do Own and ship full-stack features end-to-end, from shaping early ideas to delivering production systems used by customers daily Build complex, data-dense interfaces — review queues, journal entry editors, reconciliation workflows, agent-state visualization, financial reports — that don't break under real customer data Use AI tooling as your primary mode of writing code - Claude Code, Codex, or equivalent. AI does most of the implementation work under your direction; you own architecture, decomposition, verification, and review. Push back when AI gets it wrong — taste and judgment are why you're here, not raw typing speed. Architect backend services and APIs that handle sensitive financial data with high standards for performance, security, and data integrity Build clean, fast, and intuitive frontend experiences that translate complex financial concepts into simple user workflows Make pragmatic technical decisions balancing speed, quality, and long-term maintainability without over-engineering Debug and resolve production issues across the stack; improve observability and system resilience over time Identify and address performance bottlenecks, scaling challenges, and areas of technical debt Collaborate closely with product and design to shape roadmap and deliver meaningful user outcomes Help define how we build by contributing to code quality, architecture decisions, and team practices Mentor other engineers and raise the bar through thoughtful feedback and hands-on support What We’re Looking For 7+ years shipping production software, with at least 3 years in modern web stacks (React, TypeScript, Node, Python) Demonstrable AI-augmented engineering chops. You've actually shipped meaningful work with Claude Code / Cursor / Codex at the wheel, and can articulate what you delegate vs. what you own A track record of shipping at startup pace, with strong opinions about scope, sequence, and what's worth building Comfort working across the stack, including infrastructure and data layers Experience with cloud platforms (AWS, GCP, or similar) Strong product instincts. You think about user impact, not just implementation Ability to operate independently and make sound decisions in a fast-moving, low-structure environment Clear communicator who collaborates well across disciplines Nice to Have Backend depth - Postgres, async workers, agent orchestration patterns, LLM API integration Prior FinTech, accounting, or expense management product experience Familiarity with third-party financial APIs (e.g., Stripe, Plaid, QBO) Exposure to security, compliance, or regulated environments (SOC 2, PCI, etc.) Design system contribution - you've shipped tokens and components, not just consumed them Open-source presence or public AI-engineering writing How We Work Small, collaborative team with high ownership and low ego We prioritize progress over perfection, but care deeply about quality Engineers are expected to think, not just execute We value clear communication, good judgment, and accountability Why Join Us Competitive compensation and equity Medical, Dental, Vision plans Generous PTO, plus company holidays Remote-first work environment (must be able to overlap with East Coast time zone) Quarterly team offsites (you will likely need to travel to various locations) Home office setup stipend High-impact role with real ownership over product and technical direction Opportunity to build in a complex, meaningful space (financial systems matter) Direct access to leadership and fast decision-making.
