Braintrust is hiring a

Sifchain | Blockchain engineer (Cosmos SDK)

Rate per hour: $90-$135 dollars

As a team member, you would be responsible for creating technically viable software with a team of senior engineers specializing in devops, distributed systems, system architecture, testing, and other related fields. You would be collaborating with some of the most diligent minds in the cryptocurrency industry on product direction, both on the core Sifchain team and among its partners, investors, and advisors. As an early team member, you must feel comfortable working in a fast-paced environment where the solutions aren’t already predefined.

Prior experience with Cosmo SDK and/or Tendermint is strongly preferred. Prior experience with blockchain projects is helpful but we are primarily interested in capacity to grow into the role. You should have prior experience in developing high-quality backend architecture and some passing knowledge of how such architecture principles should apply to blockchains. You should be willing to learn and extend the technical architecture of entirely new blockchain protocols.

Responsibilities

• Developing application-specific features such as liquidity pools, margin trading, liquidity mining, custom consensus logic, and order books into a blockchain at the protocol level
• Deploying, testing, and benchmarking nodes (such as validators and miners) in many different cloud environments and with different configurations
• Developing with sound testing and debugging practices
• Creating technical documentation and well-commented code for open source consumption Collaborating with developers on all parts of the stack internally for auxiliary products such as wallets and block explorers
• Participating in open source development on shared resources with external development teams
• Assisting in the evaluation of microeconomic (decision theoretic and game theoretic) attributes of a cryptoeconomic design in terms of practicality, fairness, completeness, and capital efficiency, as well as identifying and documenting the relevant assumptions and externalities
• Assisting with research of blockchain systems, understanding how they implement solutions to core blockchain problems (such as consensus, account management, cryptography, fungibility, identity, data storage, and performance), and designing ways to integrate them with Sifchain

Qualifications

• Fluency in a systems-level programming language (Golang preferred).
• Experience with Cosmos SDK blockchain software development on at least one popular ecosystem.
• Familiarity with the user experience for cryptocurrencies; including software elements like wallets, block explorers, testnets, 3rd party custodians, and node status visualizers; text elements like developer documentation and tutorials; and event elements like price volatility, feature announcements, and partnership announcements
• Experience with developing complex software systems, scaling to substantial data volumes or millions of users with production quality deployment, monitoring and reliability.
• Understanding of the tradeoffs of performance, compute, and memory and simultaneously optimize for all three.
• Experience with deploying complex applications on cloud platforms using a container orchestration platform, such as Kubernetes.
• Familiarity with distributed programming models
• Ability to decompose complex business problems and work with a team in solving them
• Ability to think about protocol design, network design, and systems design from first principles
• Understanding of rational decision-making among agents and the systemic effects thereof
• A keen aptitude for sharp feedback and structured communication
• Desire to work on building things the "right" way to make sure our technical foundation is solid as we build on top of it over the coming years
