## Job description

Mission

To secure the next generation of the web

For web3 to get into the hands of mainstream users, there cannot be exploits that steal millions of dollars in a single atomic transaction. The current exploit detection and response solutions are not sufficient to keep billions of dollars secure. We believe a combination of research-based and data-driven detection solutions and a novel response solution will leapfrog the industry forward in the battle against exploiters.

## Role

- Join the 0 → 1 journey in building foundational infrastructure for blockchain technology to be secure.
- Thanks to changes in 2022 - 2024, blockchains are getting faster, cheaper, and multi-platform.
- We’re working to be the leader in blockchain security in this cycle.\

## Responsibilities

- Sales: As a founding team growth hire, you will support top-of-funnel demos and post-conversion success, working directly with the CEO on founder-led sales toward product-market fit.
- Sales: Bring sales techniques, experience, and network to grow Guardrail’s customer count and value to the next level.
- Content & Marketing: Create momentum across key narratives for Guardrail by building a content strategy and partnering closely with the CEO and CTO.
- Wear many hats: bring diverse ideas and perspectives and contribute to building a high-performing team culture at Guardrail.

## Requirements

- 3+ years of experience managing complex, business function workloads like Product, Sales, Strategy
- Interest in Blockchain, Security, and experience working with technical stakeholders in previous roles
- Characteristics we emphasize for this role: detail-oriented, communication (written & oral), and critical thinking (asking questions)
- Ability to handle the breadth of scope as a [founding member](https://www.lever.co/blog/startup-hiring/) of the company
- Interested in technical concepts: security, blockchain, decentralized finance: all these topics are inherently technical and having an interest in analytical thinking/problem solving.

## About Guardrail.ai

## Company Overview
- **One-liner**: Guardrail is a real-time security platform that monitors onchain financial activity, detects threats across web3 protocols and stablecoins, and autonomously triggers defensive actions — now operating as part of Rain, the global stablecoin payments platform.
- **Entity Type**: Private — Acquired/Merged (operating subsidiary of Rain, complete June 16, 2026; previously an early-stage VC-backed startup)
- **Headquarters**: 2261 Market Street, Suite 4777, San Francisco, CA, United States
- **Founded**: 2023 (per PitchBook; the team's own "next chapter" post says the journey started four years before the 2026 acquisition, suggesting earlier work began ~2022)
- **Founders**: Samridh Saluja (Founder & CEO)

## Core Business
- **Primary industry**: Blockchain / web3 cybersecurity — real-time DeFi security, onchain threat detection, autonomous incident response
- **Target customers**: DeFi protocols, stablecoin issuers, exchanges, regulated institutions, custodial infrastructure, bridges, and AI agents operating onchain (B2B / enterprise)
- **Mission**: "Make onchain payments safer for all" by offering proactive, real-time security monitoring that protects protocols, assets, and users.

## Products & Services
- **Real-Time Onchain Firewall**: A security layer that executes checks per block, function, or event across testnet, app-chains, and mainnet; scans transactions sub-second across 30+ chains to protect smart contracts, wallets, bridges, and mempools.
- **Guardrail "Guards"**: Custom-fit, programmable checks on each transaction's logic and state, covering economic risk and invariants; flag risks in real time and respond automatically.
- **Autonomous Response Engine**: Auto-triggers protective actions when risk is detected — pausing functions, flagging wallets, or escalating to the team — connected to CI/CD, ops stacks, and on-call systems.
- **Pre-Production Threat Simulation**: Stops known exploits before production by simulating risky transactions and enforcing runtime checks.
- **Enterprise Compliance & Monitoring**: Monitors transaction flows and offchain inputs, surfaces context-aware alerts for threats/anomalies/policy breaches, and supports regulatory compliance in real time.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total funding not publicly disclosed; notable operational metrics include:
  - **$5B+ assets protected** (per homepage marketing copy) vs. **over $30B onchain assets protected across 30+ chains** (per the June 2026 acquisition post) — conflicting reports, likely reflecting different points in time
  - **180+ contracts monitored**, with an additional "295+" metric listed on the homepage (unit not specified)
  - **200+ security incidents resolved** (team track record)
  - **9-figures in combined loss mitigation** for customers since going live
- **Notable Investors/Partners**: Rain (global stablecoin payments platform, acquirer); "Backed by leading Web3 investors" per the About page; the homepage references integration with leading protocols and exchanges, plus design partnerships with Rain on security architecture
- **Growth Signals**: Acquired by and folded into Rain's globally scaled stablecoin payments platform (June 16, 2026); expanded from DeFi protocols to bridges, custodial infrastructure, and exchanges; supported customers "from day-one launches to IPOs"; small but high-leverage team of 8 employees; now shipping across 15+ Rain networks

## Competitive Advantages
- **Real-time, not retroactive**: Unlike static audits and rulebooks, Guardrail scans transactions per block/function/event sub-second and responds automatically before incidents become losses.
- **Autonomous response**: The platform doesn't just alert — it pauses functions, flags wallets, and escalates automatically, closing the gap between detection and remediation.
- **Modular architecture**: Designed to defend many onchain applications (DeFi protocols, stablecoins, bridges, custodial infrastructure), making it adaptable to new attack surfaces and AI-driven adversaries.
- **Deep domain talent**: "One of the very few groups in the world operating at that depth" (per Rain Co-founder Charles Yoo-Naut) — a team of 8 with rare combined experience in blockchain security, protocol design, AI models for Fortune 500s, and high-scale software development.
- **Embedded context via Rain**: As an in-house part of Rain, Guardrail gains unique transaction-flow context that no standalone vendor can accumulate, powering faster and more accurate threat decisions.

## Strategic Focus
- **Deepening Rain integration**: Embedding Guardrail into Rain's full transaction flow across 15+ networks to provide real-time protection for Rain's global stablecoin payments platform.
- **Stablecoin security specialization**: Doubling down on the vertical where production-grade security demand is concentrating most heavily.
- **AI-adversary readiness**: Continuously adapting detection and response to AI-driven attackers targeting each layer of the stack — data, security, and response layers.
- **Expanding runtime protection**: Securing smart contracts, wallets, bridges, and mempools with context-aware onchain monitoring and enterprise-grade compliance features.

## Why Work Here
- **Small, elite team**: 8 employees working on frontier security problems; a mission-driven environment where each engineer meaningfully shapes the product.
- **High impact**: Team protected $30B+ in onchain assets and saved customers a combined 9-figures in loss mitigation — an unusually direct line between your work and real money saved.
- **Now backed by Rain's scale**: After the 2026 acquisition, the team has the resources and distribution of a global payments platform while retaining its security-specialist focus.
- **Learning surface**: Opportunity to work across protocol design, AI/ML behavioral detection, real-time systems, and multi-chain infrastructure.
- **Strong security-culture credibility**: Track record spans resolving 200+ incidents and partnering with teams from day-one launches to IPOs.
- **Work policy/perks**: Remote/hybrid policy and compensation details are not publicly available; open roles are listed on the company's careers page [jobs.gem.com](https://jobs.gem.com/guardrail-ai).
