Role description
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
• Design, engineer, and audit Gensyn's solidity smart contracts
Responsibilities
• Write smart contracts which orchestrate ML workflows and the arbitration/settlement of our verification systems
• Conduct security audits of the above contracts and their integration points with the rest of the Gensyn codebase
• Test and debug to ensure that the code is production ready
Competencies
Must have
• Very strong production experience in Solidity - specifically with respect to smart contracts handling non-trivial funds
• Lower level systems programming experience and/or full stack experience
• Strong understanding of Rollups
• Familiarity with modern testing frameworks (e.g. Mocha and Chai)
Preferred
• Experience writing smart contracts which interact with oracles
• Exposure to venture-backed start-up environments
• A conceptual understanding of machine learning workflows
Nice to have
• Experience with AI systems in production
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.
