About the job
Machine intelligence will soon take over humanity’s role in knowledge-keeping and creation. What started in the mid-1990s as the gradual off-loading of knowledge and decision making to search engines will be rapidly replaced by vast neural networks - with all knowledge compressed into their artificial neurons. Unlike organic life, machine intelligence, built within silicon, needs protocols to coordinate and grow. And, like nature, these protocols should be open, permissionless, and neutral. Starting with compute hardware, the Gensyn protocol networks together the core resources required for machine intelligence to flourish alongside human intelligence.
The Role
- Secure Gensyn’s decentralized systems, tooling, protocols and services
Responsibilities
- Own and develop security posture, tools, and strategy for application-level systems: web apps, APIs, and Smart Contracts
- Perform threat modeling, architecture reviews and design reviews for new features, services and protocols
- Monitor and respond to application-level security incidents
- Stay abreast of emerging threats relevant to our stack and proactively apply mitigations
- Educate teams across the company on security best practices
Competencies
Must Have
- Deep hands-on application security experience in production Web3 environments
- Experience securing and monitoring crypto keys and safes
- Experience performing threat modeling, architecture risk assessments and application vulnerability management
- Deep understanding of web application and blockchain security
- Familiarity with cloud-native infrastructure/applications and ability to secure them end-to-end
- Strong ability to review and write secure code
- Excellent written and verbal communication
- Comfortable operating in a high-autonomy, high-velocity team
Preferred
- Familiarity with machine-learning infrastructure or distributed systems
- Experience with threat-hunting, adversary simulation, or advanced persistent-threat (APT) mitigation
- Open source security tooling contributions or public writing about application security
Nice to Have
- Familiarity with GPU/accelerator environments, large-scale model-training workflows, or supply-chain risks in ML/AI
Compensation / Benefits
- Competitive salary + share of equity and token pool
- Fully remote work - we currently hire between the West Coast (PT) and Central Europe (CET) time zones
- Visa sponsorship - available for those who would like to relocate to the US after being hired
- 3-4x all expenses paid company retreats around the world, per year
- Whatever equipment you need
- Paid sick leave and flexible vacation
- Company-sponsored health, vision, and dental insurance - including spouse/dependents [🇺🇸 only]
Our Principles
Autonomy & Independence
- Don’t ask for permission - we have a constraint culture, not a permission culture.
- Claim ownership of any work stream and set its goals/deadlines, rather than waiting to be assigned work or relying on job specs.
- Push & pull context on your work rather than waiting for information from others and assuming people know what you’re doing.
- Communicate to be understood rather than pushing out information and expecting others to work to understand it.
- Stay a small team - misalignment and politics scale super-linearly with team size. Small protocol teams rival much larger traditional teams.
Rejection of mediocrity & high performance
- Give direct feedback to everyone immediately - rather than avoiding unpopularity, expecting things to improve naturally, or trading short-term pain for extreme long-term pain.
- Embrace an extreme learning rate - rather than assuming limits to your ability / knowledge.
- Don’t quit - push to the final outcome, despite any barriers.
- Be anti-fragile - balance short-term risk for long-term outcomes.
- Reject waste - guard the company’s time, rather than wasting it in meetings without clear purpose/focus, or bikeshedding.
