Web3 Protocol Engineer
At PowerLoom, we are building a decentralized protocol that will be considered as a gold standard
for guaranteeing integrity of data that lives on any decentralized protocol and the state of which undergoes transitions continually.
for serving rich data on demand powered by an ecosystem of peers and stakeholders that are incentivized to participate in the protocol.
The protocol generates snapshots of analytics/insights/statistics extracted from any stream of blockchain data backed by cryptographic proofs. We are aggressively pursuing a mainnet release by end of 2023, and for that we are looking for developers with hands-on experience in building and composing decentralized and distributed systems that power data APIs across a spectrum of frontend and backend technologies.
This position allows you to be fully remote and comes with all the benefits and room for creative freedom that one would expect from such a role. We meet once every 8-10 weeks to converge on our direction, touch base and keep the team spirit intact.
Before you apply
Expertise in a narrow subset of specific networking/web/data analytics/ML frameworks or libraries, for example, Django/Flask/Pandas/NumPy/SciKit does not translate well into the capabilities required for this role and such applications will not be considered.
Please do not apply in case you don't have the freedom to join on an immediate basis or have an inconveniently long notice period (>4 weeks) at your present employment
The following links will help you get a complete picture of the work we do and the systems we build. When you apply, do mention in brief in your introduction note on any specific area/component/subsystem of PowerLoom Protocol that you see yourself readily contributing to based on the skill and experience you have gained so far, if you had the opportunity to do so. All applications without a valid introduction note will be rejected.

Expected skills and responsibilities
An ability to learn and apply new concepts in a rapid iterative approach will be taken into account wherever prior experience might not be available or applicable.
Share links to your open source contributions or projects to expedite the selection process. Original projects, hacks, bounty submissions have the potential to get a pass straight to the technical evaluation round without a screening round.
Language proficiency in order of priority (bonus points if you are equally proficient in all)
- Fundamentals of blockchain protocols - low level network communications, data structures used for blocks/transactions/proofs/storage, RPC interfaces with nodes
- Secure, modular smart contract development along with knowledge of low level interfacing of the language with the Virtual Machine on which the smart contract runs
- Hands on knowledge of at least two major DeFi protocols - the math behind them, their smart contract design and architecture, composability use cases of combining them to make money legos.
Regardless of web3 specific experience, it is also important to have solid grounding in building systems that scale and self-correct to ultimately provide value to all clients of PowerLoom Protocol.
Ability to architect and map out systems
- interaction between services, subsystems with appropriate sequence diagrams, flow charts, etc
- catastrophic failure scenarios and emergency measures
- unambiguous monitoring, observability and self-reporting capability of services and systems
HTTP request-response cycle profiling, debugging, optimization
Computer Science fundamentals
- Data Structures and Algorithms - trees, stacks, queues, graphs
- Theory of computation - Finite Automata, state transitions
- TCP/IP, knowledge of low level interfaces to Layers 4-7 of the networking stack
- Operating Systems
- file systems
- POSIX standards
- separation of concerns and privileges between kernel and user space
concurrency and parallelism constructs in
- distributed worker models
- functional programming and data engineering paradigms such as map-reduce, filtering to scale up operations like batched processing, insight generation that run in the backend
strategic use of data structures native to specific caches and storage technologies
Rapid prototyping of API designs, mock API consumption patterns and dogfooding
- knowledge of one or more frameworks like React/Vue/Angular/Svelte/Next
- building dashboards to provide insights into metrics, datasets, and supporting all around observability of systems
What do you get out this
With any engineering role at PowerLoom Protocol, you will be working on bleeding edge stuff at the 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. One can be rest assured that pursuing a career with us and joining the core founding team will empower them to reap the oppprtunities coming up in the decentralized software development world in the near to long term future.
Remote Work Culture - Benefits and Expectations
- Flexible work hours and zero micro-management over hours clocked and other trivial issues
- Being healthy and fit is an integral part of our company culture and our internal communication channels on Slack mirror the same attitude
- Ability to communicate and coordinate asynchronously makes or breaks remote teams. We expect commitment towards the same from all members of the team. Be adept at long form, asynchronous communication at every step of the planning and development lifecycle -
- document design decisions
- maintain architecture diagrams and references for all modules
- present all information on Slack without the need for second-guessing and extrapolation from other team members
- Ask questions to your assigned mentor as well as all stakeholders involved in design, development and testing of the feature/codebase/architecture
- Wherever there is a need for synchronous communication with team members, coordinate well in advance and block each other's calendars to minimize scheduling conflicts
- 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 you are passionate about solving complex data storage and fingerprinting puzzles, and have already worked on open source projects and/or production scale code, go ahead and apply. You won't be disappointed.
