Backend-Leaning Product Engineer

About the Role

Join a small, high-ownership product team at an early-stage B2B SaaS startup as a backend-leaning product engineer . You'll own customer-facing features end-to-end, navigate messy integrations and legacy systems, and make product and engineering trade-offs with speed and strong judgment. This is a role for someone who thrives in ambiguity, moves fast, and cares deeply about shipping real products that customers use.

What You'll Do

Own features end-to-end — from design through shipping and iteration — with minimal PM oversight.

Build and maintain backend systems, APIs, data models, and automation pipelines.

Integrate with external tools, legacy systems, and third-party services.

Design workflows and orchestration for AI/automation-driven product features.

Debug production issues and exercise strong engineering judgment under pressure.

Collaborate closely with founders, customers, and cross-functional stakeholders in a hybrid San Francisco setting.

Balance full-stack work when required, with a clear emphasis on backend ownership.

What We're Looking For

Required:

Backend-focused software engineering with hands-on experience designing, implementing, and shipping customer-facing features.

Demonstrated ownership of the full feature lifecycle — ideation, implementation, and iteration based on customer feedback.

Track record of shipping real products, ideally in 0-to-1 or ambiguous, fast-moving environments.

Strong cross-functional collaboration and communication skills.

Must be legally eligible to work in the US without employer sponsorship.

Based in San Francisco or willing to relocate; hybrid/in-office presence required.

Nice to Have:

Experience with applied AI, agentic workflows, RAG pipelines, or LLM-enabled features.

Python proficiency (modern web/backend stacks considered — engineering quality matters more than specific stack).

Systems integration experience with external APIs and legacy platforms.

Early-stage startup experience or founding engineer background.

Not a fit if you are: frontend-only, data/internal-tools-only, pure DevOps/SRE without product ownership, pure research ML without shipping experience, or primarily motivated by corporate titles.

Compensation & Benefits

Base salary: up to $275,000 depending on experience.

Equity: meaningful equity package.

No visa sponsorship available.

Location

San Francisco, CA — hybrid/on-site. Candidates must be based in SF or willing to relocate.
