Hexagate is a leader in real-time Web3 security, helping blockchains, DeFi protocols, asset managers, and exchanges detect and mitigate all types of on-chain risks and threats. Our solutions proactively monitor and analyze smart contracts, transactions, wallets, and blockchain interactions to prevent financial crime and exploits before they happen. We work with some of the largest players in crypto and DeFi, secure tens of billions of dollars and help them to operate and build on-chain faster and in the most secure and reliable way possible.

As a Solutions Architect, you will act as a trusted security and technical advisor for customers throughout their journey, from initial evaluation to post-sales deployment. This hybrid pre- and post-sales position blends blockchain security, client consulting, sales support, and technical integration. You will collaborate directly with leading Web3 teams to understand their security challenges, develop real-time threat detection strategies, and ensure smooth implementation of Hexagate's solutions. This role demands technical problem-solving skills, strong blockchain security knowledge, client-facing abilities, and a proactive approach to ensuring customer success.

In this role, you’ll:

• Partner with Account Executives and Inside Sales reps to run discovery calls, security risk reviews, and product demos

• Help prospects evaluate Hexagate’s capabilities, align solutions with their risk profile, and build proof-of-concepts

• Design and deploy customized real-time monitoring solutions for smart contracts, transactions, and blockchain entities

• Lead technical onboarding and solution deployment, including custom monitor rules, API integrations, and alerting workflows

• Assist with integrations into customer pipelines and tools

• Provide ongoing advisory on threat models, detection coverage, and evolving security best practices

• Stay ahead of blockchain threats, advising customers on new attack vectors and security best practices

• Act as the voice of the customer to influence product roadmap

• Document implementation patterns and best practices

• Help scale Hexagate’s customer success and enablement playbooks

We’re looking for candidates who have:

• 3+ years of experience in a technical role such as Solutions Engineer, Security Engineer, Sales Engineer, or Blockchain Analyst

• Strong knowledge of Web3 security, including smart contract vulnerabilities, DeFi risks, and blockchain transaction monitoring

• Hands-on programming experience and APIs for data integrations and monitoring configurations

• Ability to read Solidity and analyze smart contract interactions (some coding experience is a requirement)

• Excellent communication skills, with the ability to explain complex security concepts to both technical and non-technical audiences

• Experience in customer-facing roles, particularly in security, risk management, or blockchain-related industries

• A self-starter mindset, with the ability to work independently and handle multiple accounts

Nice to have experience:

• Background in cybersecurity, fraud detection, risk management in DeFi, or security in blockchain environments

• SQL, Python, or other scripting experience for querying blockchain data

Technologies we use:

• Solidity & smart contract security tools

• SQL, Python, and scripting tools for data analysis
