Software Engineer, Partnerships

at Merge API

San Francisco, United States

Merge is the leading provider of agentic tools and customer-facing integrations for frontier LLMs, Fortune 500 organizations, and B2B SaaS companies. Our platform offers two core products: Merge Unified, which enables businesses to add hundreds of integrations to their products with a single API, and Merge Agent Handler, which empowers AI agents with secure access to thousands of third-party tools. Merge's enterprise-grade platform handles the entire integration lifecycle, from authentication and security to monitoring and maintenance. Thousands of companies trust Merge to accelerate product development, unblock sales, reduce customer churn, and save engineering resources—allowing them to focus on their core product.

Merge is looking for a driven Partner Operations Manager…

Merge already powers integrations inside thousands of products. The next step is making Merge available everywhere developers and AI agents are already building: inside workflow platforms, agent frameworks, cloud marketplaces, and partner ecosystems. We are hiring a founding engineer to own this surface area. You will build the integrations that bring Merge into popular third-party platforms, and you will build the core product features that make those integrations possible. This is not about adding connectors to Merge's existing catalog. This is about expanding where and how Merge gets used by embedding our capabilities into the ecosystems that matter most.

What You Will Do:

Build production integrations that bring Merge into third-party ecosystems: agent builders, workflow automation platforms, cloud marketplaces, and developer toolchains
Design and ship core product features that unlock new distribution channels and allow Merge to operate natively in environments beyond our own dashboard and API
Collaborate directly with external partner engineering teams to scope technical requirements, build joint integrations, and get Merge into partner storefronts and marketplaces
Own the full lifecycle of partnership integrations from architecture and prototyping through submission, review, and production launch
Identify and build the abstractions, SDKs, and developer surfaces that make it faster to integrate Merge into the next platform, reducing time-to-launch for each new ecosystem partnership
Work closely with the partnerships, product, and GTM teams to prioritize which ecosystems to enter based on customer demand, strategic value, and technical feasibility

The ideal candidate will have:

4-7+ years of full-time software engineering experience
Experience building integrations into or on top of third-party platforms (e.g., marketplace apps, plugins, workflow nodes, agent tools, or platform extensions)
Deep familiarity with API design, authentication patterns (OAuth 2.0, API keys), and the developer experience of consuming and exposing APIs
An ability to perform in a fast-paced environment dealing with ambiguous technical challenges. Many of the ecosystems you build for will have immature documentation, evolving specs, or no precedent for what you are shipping
Experience with Python
Extensive knowledge of SQL databases (Postgres preferred)
A product-minded approach to engineering. You care about why something is being built, not just how, and you can make scope and prioritization tradeoffs without waiting for a spec

Compensation

The cash compensation range for this role is $150,000 - $175,000.
Actual compensation packages are based on a wide array of factors unique to each candidate, including but not limited to skill set, years & depth of experience, certifications. In addition to cash compensation, all employees receive an equity compensation package.
