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.
