Business Development & Growth Manager

You'll lead outbound business development for Sigma Prime's Web3 security assessment services while helping establish the market, partnerships, and customer pipeline for Secstant, an AI-assisted security review tool in development, and Bombora, an Ethereum block builder. You'll work directly with Sigma Prime's directors and collaborate closely with security, research, engineering, and operations teams. This is an opportunity to shape the growth function within an established and highly technical Web3 organisation, rather than inheriting an established sales process. This is not a high-volume transactional sales role; the work is technical, reputation-driven, and often involves long sales cycles, built on credibility, sound judgment, persistence, and trusted relationships developed over time.

Responsibilities

• Identify and approach prospective clients for security assessment, embedded security, and specialist engineering services
• Build strong relationships with founders, engineers, security leaders, investors, ecosystem organisations, and other decision-makers across Web3
• Develop commercial and ecosystem relationships for Secstant as the product progresses towards early access and wider availability
• Identify potential customers, design partners, integrations, and strategic partnerships for Secstant
• Build relationships across the MEV, searcher, relay, validator, DeFi, and broader Ethereum ecosystems relevant to Bombora
• Represent Sigma Prime at selected industry conferences and ecosystem events several times per year
• Manage early commercial conversations and coordinate technical discussions with directors, Security Assessment Managers, researchers, and engineers
• Implement and maintain scalable CRM and business development processes
• Establish practical reporting and metrics across pipeline generation, conversion, sales cycles, relationship development, and channel performance
• Research prospective markets, competitors, customer needs, and emerging opportunities
• Contribute to proposals, partnership discussions, and go-to-market planning
• Support product discovery by gathering structured feedback from prospective users and ecosystem participants
• Contribute to articles, product updates, case studies, conference material, and other written content where relevant
• Help improve Sigma Prime's broader approach to positioning, communications, and growth

Requirements

• Experience in business development, partnerships, technical sales, ecosystem growth, or a related commercial role
• Existing understanding of Web3, Ethereum, cybersecurity, developer tooling, or other highly technical markets
• Comfortable initiating conversations and building relationships through thoughtful outbound activity
• Able to communicate credibly with both commercial decision-makers and highly technical founders and engineers
• Enjoy developing opportunities in markets where the product, customer segment, and sales process are still evolving
• Take ownership of follow-ups and maintain a disciplined approach to pipeline management
• Able to introduce structure without creating unnecessary process or administration
• Write clearly and can explain technical products without relying on exaggerated claims or generic sales language
• Comfortable working directly with company directors and senior technical staff
• Operate well independently in a remote environment
• Willing and able to travel internationally for several conferences or industry events each year
