- **Company:** Ampersand
- **Location:** San Francisco, CA
- **Employment:** full-time
- **Work type:** hybrid
- **Posted:** 2026-06-18

## Job description

## OUR MISSION

At Ampersand, we are building scalable integration infrastructure that delivers real-time context to AI agents in seconds. Our declarative platform, 150+ open-source connectors, and embeddable UI components give developers the building blocks they need to ship deep, bidirectional integrations.

We power cutting-edge AI companies like 11x, Orb, Square, and Crunchbase. Almost every engineering team that has evaluated us against other solutions has chosen to use Ampersand. As our product and brand evolve, we're looking for great people to join our experienced team of former Firebase, AWS, Meta and Square engineers and operators.

## ABOUT US

Ampersand was founded in 2022 by Ayan Barua and Lauren Long — two engineers and repeat founders with a rare combination of developer tools and SaaS experience. You can learn more about our full team here https://www.withampersand.com/about.

We've raised Series A funding from top-tier investors known for their early-stage bets on generational companies like Anthropic, Apple, Twilio, Supabase, and Vercel.

Together, we believe:

- This is a once-in-a-generation opportunity to build the connectivity infrastructure for AI. Seizing this moment requires passion, hard work, and continuous learning. At the same time, this is a marathon, not a sprint.
- Velocity comes from great strategic decisions, not doing the 99 things you don't have to do.
- In five core values that shape how we work every day: Craft, Customer Empathy, Ownership Mindset, Velocity, and Humility.

## THE ROLE

We're hiring a Product Engineer to shape the user experience of a platform used by some of the most technically sophisticated teams in software and AI.

This is a foundational role. You'll work closely with the founders, engineers, and customers to design experiences for complex, developer-facing workflows — and help establish the design standards the product will be built on from here. The team is small, the ownership is real, and the people you'll work with care deeply about craft. If you do your best work when the problems are hard and what you ship actually matters, then this is the environment for it.

## WHAT YOU’LL OWN

- Full Stack Feature Development — Own the full loop: technical architecture, implementation, documentation, and customer communication. No throwing work over the fence. You will primarily work in the backend (Golang), but you are also comfortable implementing frontend features (React).
- Customer Engagement — Talk directly to customers — support questions, feedback gathering. Let what you hear shape what you build.
- API Design and Architecture — Every engineer proposes API designs and technical architecture for the features they work on. We write succinct design docs, generously give each other feedback, and push towards the best solution.
- Scale and Reliability — We are rapidly scaling our customer base, so we need to build with scale and edge cases in mind. Every engineer contributes to building alerting, telemetry, internal tooling, and automation to help us continue to ship fast while maintaining reliability.
- AI Agents — In addition to our platform, we are building AI agents both of our own use and to ship to our customers. You will work on planning, tool use, evals, observability, guardrails, and the infrastructure needed to make agentic workflows reliable for customers.

## WHAT YOU’LL BRING

- 4+ years engineering and designing digital products, ideally in B2B SaaS, developer tools, enterprise software, or technical products
- Golang and React experience is a strong plus
- You are AI-forward and love trying new AI tools. You think of yourself not as a coder, but as a builder who harnesses AI to multiply their productivity.
- Strong communication skills; you can articulate design decisions and push back when something isn't right. Engineers here write their own feature docs and own their decisions
- Great taste in what makes developer tools intuitive; ideally you've shipped customer-facing developer products before
- Strong product intuition — you can work directly with customers to design features, not just implement specs

## THE PERKS

- Competitive salary and equity
- Medical, dental, and vision insurance
- Free lunch on in-office days (Mon/Tue/Thu)
- 401(k) with company match, commuter benefits, HSA
- Up to 4 weeks PTO
- Team socials and retreats

## About Ampersand

## Company Overview
- **One-liner**: Ampersand provides a declarative developer platform for building native, bi-directional product integrations with customers’ CRM and GTM applications.
- **Entity Type**: Private (Seed stage)
- **Headquarters**: San Francisco, California, United States
- **Founded**: 2022
- **Founders**: Ayan Barua (Co-founder, CEO) and Lauren Long (Co-founder, CTO)

## Core Business
- **Primary industry/industries**: B2B SaaS developer tools, infrastructure for integrations
- **Target customers**: Product and engineering teams at B2B SaaS companies (especially those building AI agents or platforms that need to sync with customer systems of record)
- **Mission or purpose statement**: Enabling B2B AI Agents to sync with their users’ System of Records for real-time context (from LinkedIn)

## Products & Services
- **Ampersand Platform**: A declarative framework that lets developers define integrations in a manifest file (`amp.yaml`), covering reads, writes, and event subscriptions. Includes a managed server that handles auth, retries, cost/ quota management, and a set of embeddable UI components for customer configuration.
- **Open Connectors Library**: An open-source library of pre-built connectors for popular SaaS tools (Salesforce, HubSpot, Marketo, Dynamics, and hundreds more). Developers can contribute or request new connectors.
- **Proxy API**: Authenticated passthrough requests for custom or unsupported objects/fields.
- **AI SDK**: Official SDK to enable AI agents to read/write customer data in real time.

## Market Standing
- **Valuation/Market Cap**: Not publicly disclosed
- **Key Metric**: Total funding of $4.7M (Seed round, April 2023); estimated annual revenue of $2.4M
- **Notable Investors/Partners**: Matrix Partners (lead), basecase capital, Flex Capital, Blue Moon VC
- **Growth Signals**: +14.3% YoY employee growth (13 employees); expanding into AI agent use case; active GitHub repositories with rising stars; strong employer rating (5.0/5.0 on LinkedIn)

## Competitive Advantages
- **Open-source first**: An open connectors library that gives developers full control and extensibility, differentiating from closed “unified API” platforms.
- **Declarative and version-controllable**: Integrations are defined in code (YAML), composable, and fit into existing CI/CD pipelines – avoiding drag-and-drop editors that are hard to scale.
- **Bi-directional and customer-configurable**: Supports both read and write, plus real-time event subscriptions, with dynamic field mapping for enterprise customers.
- **Built for product use**: The platform is designed to be exposed directly to end users through embeddable UI components, reducing the engineering burden of building integration management interfaces.

## Strategic Focus
- **Current priorities**: Deepening support for AI agents by enabling real-time sync with systems of record; expanding the connector library (recently added Billing, new integrations); maintaining a lean, highly technical team.
- **Direction for growth**: Become the standard integration layer for B2B SaaS products, especially those incorporating agentic AI. Continued investment in developer experience and open-source community.

## Why Work Here
- **Culture highlights**: Rated 5.0/5.0 on LinkedIn (1 review) with perfect scores for Work-Life, Compensation, and Culture. Described as a small, fast-moving team where engineers have high ownership.
- **Remote/hybrid policy**: HQ in San Francisco, with team members in Nepal and Canada, suggesting a remote-friendly or distributed hybrid setup.
- **Notable perks/engineering culture**: Employees come from top tech companies (Square, Amazon, Meta). Tech stack includes TypeScript, Go, React, Terraform. Emphasis on open-source contributions and developer-facing products. The team is small (13 people), offering significant impact and visibility.
