Web3 Protocol Systems Engineer: Golang

About Powerloom

Powerloom Protocol is a composable data network primarily aimed at serving the onchain data needs of smart contract-based applications within DeFi, GameFi, NFTs, and more. We incentivize participating peers to reach a consensus on state transitions and event emissions observations across many smart contracts. By utilizing data compositions on atomic, consensus-backed units of data, Powerloom stands as a peer-validated and accurate information source, empowering rich data applications like dashboards, bots, aggregators, and insights trackers.

  • Applications of cryptography for efficient storage

What do you get out this

Just as with any engineering role at PowerLoom Protocol, you will be working at an exciting intersection of diverse techincal as well as non-technical fields like Web3 tools/frameworks/protocols, decentralized/distributed systems, game theory, cryptoeconomics, DeFi(decentralized finance), to name a few. You will be interfacing with multitude of internal as well as external stakeholders in relation to the systems that you will be responsible for.

Remote Work Culture - Benefits and Expectations

• Flexible Work Hours: Enjoy freedom with flexible work hours, and experience zero micro-management over hours clocked and other trivial issues.
• Health and Fitness Culture: Being healthy and fit is an integral part of our company culture. Our Slack channels mirror this wellness-focused attitude.
• Asynchronous Communication is Key: Ability to communicate and coordinate asynchronously is vital for the success of remote teams. We expect every team member to be committed to this communication style. Be adept at long-form, asynchronous communication throughout every step of the planning and development lifecycle.
• Documentation and Clarity: Document all design decisions. Maintain architecture diagrams and references for all modules. Ensure clear and complete information presentation on Slack, eliminating the need for second-guessing and extrapolation by other team members. Proactively ask questions to your assigned mentor and all stakeholders involved in the design, development, and testing of the feature/codebase/architecture.
• Synchronous Communication: When synchronous communication is required, coordinate well in advance. Block calendars mutually to minimize scheduling conflicts and ensure productive discussions.

General Must-haves

• Ability to listen unbiasedly and gather requirements as accurately described in calls/meetings, architectural discussions and engineering documents
• Ability to clearly communicate progress, blockers and perform independent research
• Ability to document and take ownership of the functional correctness of any assigned work
• Ability to quickly iterate, learn from mistakes and apply lessons from the same as future strategy

Cherry on top

These skills are not a strict requirement to qualify for the role yet can add the extra edge required to engineer a protocol like PowerLoom:

• Experience of working extensively with Git and project management tools that enable fast development and coordination across multiple teams in the future
• Experience with NoSQL data stores and caches like Redis/Memcached
• Knowledge of Unix/Linux fundamentals - shell scripting, CLI tools etc.
• Familiar with deploying and managing services on cloud platforms like AWS/GCP/Azure

If the vision of fostering a vibrant, interconnected Web3 ecosystem excites you, we urge you to apply.

We promise, you won't be disappointed.
