Job Description

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.
