AI Engineer - Agents

Department: Engineering

Location: San Francisco

Compensation: $180K – $300K • Offers Equity

Employment Type: FullTime

About Us

Campfire is on a mission to redefine the accounting software landscape by taking on giants like Netsuite to build modern accounting software for startups and mid-size tech companies. We graduated from Y Combinator's Summer 2023 cohort, and we are backed by prominent investors like Foundation Capital and a rapidly growing customer base.

🌟 The Role

Join Campfire as an AI Engineer to build production AI agents that help customers get real accounting work done. You’ll combine strong software engineering fundamentals with hands-on experience developing and operating agentic applications, from automating financial workflows to helping customers understand and act on their financial data.

This is a hands-on technical role. You’ll shape our agent architecture, ship customer-facing features, and establish the engineering practices that make them reliable. You’ll work closely with engineering, product, and design to turn ambiguous problems into software our customers can trust

💼 We Need Someone Who

Has Expertise

• Strong software engineering background, with substantial experience designing, building, and operating production backend systems. You write maintainable Python and bring sound judgment to APIs, data models, distributed systems, and testing.

• Hands-on experience shipping LLM-powered agents used by real customers, including tool calling, orchestration, retrieval, and integration with application data and workflows.

• Experience owning agent quality in production through evaluations, tracing, monitoring, and systematic debugging of failures.

• Practical judgment around agent permissions, data access, human approvals, and recovery from partial failures, especially when agents take actions on behalf of users.

• Ability to balance accuracy, latency, cost, and complexity, and to choose when a problem calls for an agent, a deterministic workflow, or a combination of both.

• A track record of staff-level impact: leading complex initiatives, making architectural decisions across teams, mentoring engineers, and raising engineering standards while staying close to the code:

Thrives in Agility:

• Our team is lean and moves quickly. You’re comfortable experimenting, iterating, and shipping fast.

Values Autonomy:

• You take ownership end-to-end — from prototyping models to deploying and monitoring them in production.

👥 Ideal Candidate

• You’re an experienced engineer with software engineering experience who has owned consequential production systems and can explain the tradeoffs, failures, and lessons behind what you’ve shipped.

• You’ve taken AI agents beyond demos and prototypes and improved them based on real usage.

• You care about customer outcomes and bring curiosity about accounting and financial workflows. Prior fintech or accounting experience is a plus.

• You collaborate closely with engineering, product, and design, communicate technical decisions clearly, and help other engineers grow.

• You want the ownership and scope of a staff role while remaining an active builder.
