## Job description

## About StackOne

StackOne is the integration infrastructure for AI agents. Backed by GV and Workday Ventures ($24M raised), we make it possible for any AI agent — whether our customers build it into their product or buy it off the shelf — to take real action across the enterprise stack. Our platform gives agents 430+ connectors and 26,000+ pre-built actions, an AI connector builder for everything not covered yet, and the production layer agents actually need: semantic tool discovery that cuts token use by up to 80%, managed authentication and per-action permissions, the most accurate prompt injection defense on the market, and end-to-end observability. Join us on our fast trajectory to build the future of agentic integrations.

## Role

Own top-of-funnel pipeline generation as a Sales Development Representative at StackOne, fueling US revenue growth in agentic integrations, one of the fastest-moving areas of B2B AI. You'll be one of our first SDRs in the US, working directly alongside our Founding AEs and CEO to build a repeatable outbound and inbound-qualification engine from the ground up. Full ownership of pipeline creation across inbound and outbound, partnering closely with the CEO, Founding AEs, prospecting our three ICPs, running outbound sequences, and booking qualified meetings with flagship US accounts. Early motion, real traction.

## What You’ll Be Doing

- Own US pipeline generation targets tied directly to qualified meetings booked and pipeline created.
- Generate and qualify leads across inbound (PLG-driven developer traction) and outbound motions.
- Prospect three ICPs: AI-native startups building agents, enterprise teams embedding AI into existing products, and SaaS platforms embedding StackOne for their customers.
- Build and iterate on the US outbound motion (account targeting, messaging, sequencing, experimentation).
- Research accounts and personas deeply enough to speak credibly about APIs, MCP, and integration architecture in first conversations.
- Qualify inbound leads from PLG-driven developer traction and route them cleanly to the AE with strong context.
- Partner with the AE to hand off qualified opportunities and support smooth transitions into full-cycle sales conversations.
- Collaborate closely with Founding Growth (Marketing) to refine outbound messaging and sequences for technical buyers.
- Help build and test early US outbound playbooks, messaging frameworks, and account lists.
- Track and report on outreach volume, response rates, meeting-to-opportunity conversion, and pipeline contribution.

## Qualifications

- 2+ years of B2B SaaS SDR/BDR experience with clear evidence of overperformance and rapid progression.
- Strong track record of owning and hitting pipeline generation targets, not just activity metrics.
- Experience in early-stage or fast-growing startup environments.
- Experience prospecting into iPaaS/integrations, dev tools, APIs, infrastructure, security or other highly technical products.
- Comfortable researching and reaching out to engineers, CTOs, and technical founders.
- Exposure to AI/LLM products, agentic platforms, or meaningful hands-on experience with AI tools.
- High ownership mindset, bias for action, and comfort operating in ambiguity.

Dealbreaker: pure enterprise sales background with no exposure to startup environments.

## Benefits

- Join one of the best-funded, fastest-growing startups in the AI infrastructure ecosystem.
- Work alongside an experienced team, with backgrounds from Google, Microsoft, Oracle, Coinbase, JP Morgan, and more.
- Meaningful share options – share in the company's success as we grow.
- 25 days PTO + 1 additional day per year of tenure.
- Health insurance.
- 401(k).
- Remote-first, with regular in-person time in the Bay Area.
- $1,000 for your home office setup + $500/year top-up.
- Annual team offsites to sunny spots (last ones were in Croatia and Portugal ☀️)

## About StackOne

## Company Overview
- **One-liner**: StackOne provides integration infrastructure that connects AI agents to any SaaS system with 420+ pre-built connectors and prompt injection defense.
- **Entity Type**: Private (Series A — $24M total funding)
- **Headquarters**: Newbury, Berkshire, United Kingdom (registered office; team distributed globally across Europe and the United States)
- **Founded**: 2023
- **Founders**: Romain Sestier (Co-Founder & CEO), Guillaume Lebedel (Co-Founder & CTO)

## Core Business
- **Primary industry**: Integration infrastructure for AI agents; enterprise software connectivity
- **Target customers**: B2B developers and companies building or deploying AI agents (including off-the-shelf agents like Claude and Cursor) that need to take action across HRIS, ATS, CRM, LMS, IAM, documents, and other business applications
- **Mission or purpose**: Fuel innovation by connecting AI agents to software — let the agent think, StackOne takes action
- **Customer verticals**: Enterprise, SMB, and platform companies (customers include Drata, Attensi, Localyze)

## Products & Services
- **StackOne Platform**: Core integration infrastructure that exposes 25,000+ pre-built actions across 330+ connectors (now 420+). Handles authentication, rate limiting, retries, data transformation, and governance. Supports MCP, A2A, AI Action SDK (Python/TypeScript), and direct REST APIs.
- **StackOne Defender**: Open-source prompt injection detection library (two-tier defense: pattern matching in ~1ms + ML classifier in ~10ms) that scans tool responses before they reach the LLM. F1 score 0.87-0.88, runs in-process with no external API calls.
- **Falcon Execution Engine**: Next-generation engine that runs every agent action across REST, GraphQL, SOAP, and proprietary APIs. Handles auth, retries, errors, data transformation, and per-provider throttling.
- **Connector Builder**: Allows creation of production-ready connectors for any API (including SOAP, OData, proprietary) in minutes, declared as YAML in Git.
- **Permissions API**: Normalizes RBAC, scopes, and ACLs across all integrations into a single model with sub-millisecond checks and per-tenant scoping.
- **Audit Trail & Compliance**: Full logging of every API call, permission check, and credential use. SOC 2 Type II, GDPR, HIPAA, and CCPA compliant. Privacy-first architecture — no customer data stored by default.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total funding raised — $24M
  - Seed: $3.6M (Q2 2024, led by Episode 1 and Playfair; angel investment from Co-Founder of GitHub in Q2 2023)
  - Series A: $20M (May 2025, led by GV/Google Ventures, with Workday Ventures, XTX Ventures, Episode 1, Playfair, and angels from OpenAI, DeepMind, Microsoft, Mulesoft)
- **Notable Investors/Partners**: GV (Google Ventures), Workday Ventures, XTX Ventures, Episode 1, Playfair Capital
- **Growth Signals**: Surpassed 1 billion API calls; 420+ connectors and 25,000+ actions; customers across three continents; one of the fastest-growing AI agent infrastructure platforms; expanded from 20 integrations in Q4 2023 to 330+ in 2025

## Competitive Advantages
- **Privacy-first architecture**: No customer data persisted by default — proxies requests in real-time, nothing to breach.
- **Multi-protocol support**: MCP, A2A, SDKs, REST — agents connect however they want.
- **Two-tier prompt injection defense**: Open-source Defender catches threats in <4ms with 88.7% accuracy; runs in-process with no additional latency or cost.
- **Declarative connectors as code**: Every connector is a YAML file in Git — reviewable, testable, reproducible.
- **Certified compliance**: SOC 2 Type II, HIPAA, GDPR, CCPA — unlike many unification APIs.
- **Low-latency execution engine (Falcon)**: Handles rate limits, retries, and transforms data in real-time, optimized for agent context windows.

## Strategic Focus
- Continue investing in R&D for its state-of-the-art tool-calling LLM and expanding the breadth and depth of integrations.
- Scale enterprise adoption by deepening governance, permissions, and audit capabilities.
- Build out developer ecosystem (MCP servers, open-source tools) to lower friction for AI agent developers.
- Expand across new categories (IAM, messaging, documents) and increase action coverage per connector.

## Why Work Here
- **Culture & team**: Founded by a pair (CEO Romain Sestier and CTO Guillaume Lebedel) who have worked together for over a decade at Oracle, JP Morgan, Google, Microsoft, and other top tech companies. Team is distributed across Europe and the US.
- **Remote/hybrid**: Distributed team with global operations — location flexibility. Open roles include Engineering (AI, Platform, Security, UI) and GTM.
- **Growth stage**: Post-Series A ($20M from GV) — well-funded, high-growth phase with product-market fit and accelerating adoption (1B+ API calls). Opportunity to shape the infrastructure layer for the AI agent era.
- **Engineering focus**: Emphasis on security, low latency, open-source contributions (Defender), and building for developers. Stack includes modern AI/ML tooling, ONNX models, and multi-protocol systems.
- **Perks**: Competitive compensation, equity (startup), and the chance to work on the critical security/compliance layer for enterprise AI agents.
