We are a team of world class builders and researchers with expertise across several domains: Ethereum Protocol Engineering, Layer-2, Decentralized Finance (DeFi), Miner Extractable Value (MEV), Smart Contract Development, Security Auditing and Formal Verification.

Working to solve some of the most challenging problems in the blockchain space, we frequently collaborate with renowned companies, such as Ethereum Foundation, StarkWare, Gnosis Chain, Aave, Flashbots, xDai, Open Zeppelin, Forta Protocol, Energy Web, POA Network and many more.

We actively contribute to Ethereum core development, EIP’s and network upgrades together with the Ethereum Foundation, and other client teams.

About the Role

The role of our Protocol Engineering team is to build state-of-the-art blockchain clients (nodes).

• R&D working culture
• Designing and building distributed and fault-tolerant systems
• An appreciation of scalable, high availability and low latency architectures
• Implementing networking layer and P2P protocols
• Processing and management of large data sets with strict real-time performance requirements
• Optimizing software performance
• Opportunity to work with the top software engineers and research professionals to solve the toughest technical challenges
• Working with the latest tools and technologies
• Troubleshooting

Skills:

• Ability to implement efficient algorithms and design complex data structures
• Excellent programming skills, C# or GO preferred but will also consider other tech stacks (e.g. Java, Rust, C++)

• Ability to write clean, testable and maintainable code without over engineering
• An entrepreneurial nature, willing to take ownership and run towards problems
• Several years experience in software development
• Strong computer science background
• A fascination by the inner working of blockchains

It is not essential but, if you have deep knowledge in one of the following areas then we would love to talk to you:

• Distributed networks (P2P)
• Performance and memory optimisations
• Blockchain / EVM / TransactionPool / JSON RPC
• Complex data structures for example; Patricia\Merkle/Verkle tries
• NoSQL Key Values databases for example; RocksDB
• Cryptography

Examples of projects the team has worked on:

• Building an implementation of the Nethermind client from scratch
• Implementation of Snap Sync protocol that improves the speed of Ethereum node synchronization over the network
• The Merge - implementation and migration from Proof of Work to Proof of Stake
• Performance improvements to internal virtual machine (EVM)
• Improvements to memory management
• Design and implementation of efficient and robust data stores and caching
• Libp2p implementation in C#

Perks and benefits:

• Fully remote
• Flexible working hours
• Plus equity

Note to all applicants: Biconomy are a fully remote company with a team dispersed all over the Globe, so we welcome applications from all candidates, regardless of your location.

Join a leading Web 3 company that’s enabling and powering the builders of the new internet!

Biconomy’s foundations were built on making Web 3 accessible and simple to all. We do this by making blockchain transactions seamless, and by doing so, we are accelerating the mainstream adoption of Web 3.

That’s why ease and accessibility are imperative to our innovations and solutions. While we build for developers, our work radically simplifies the overall user experience on Web 3. By abstracting away blockchain complexities, the end user enjoys the benefits of Web 3 with the familiarity of Web 2.

We are already solving for some of the leading players in the blockchain space & are emerging as the default transaction stack for Web 3. Some of our numbers:

• Processed 22 million transactions
• Facilitating over $233 million of transfer volume
• Saving users over $4.7 million in gas fees!

What are we looking for?

We’re looking for a protocol engineer to work within the Protocol Team in designing and implementing Biconomy’s Multichain Relayer Protocol. You will collaboratively take ownership of the protocol’s design, construction, and development.

We are looking for a highly experienced core developer with relevant experience in implementing solutions to core blockchain problems (such as consensus, account management, cryptography, storage, identity, and performance)As web3 networks mature, the demand for highly intuitive and nuanced user experiences has grown. At the same time, the demand for decentralization is at an all-time high.

To achieve these design goals, we need a core developer to collaboratively design, build and evolve the core decentralized infrastructure capable of censorship resistance and, simultaneously, deliver user experience exceeding those offered by legacy networks.

What will you be doing?

• Working within the Protocol Team in designing and implementing Biconomy’s Multichain Relayer protocol
• Researching external blockchain systems and understanding how they implement solutions to core blockchain problems, designing ways to integrate them with Biconomy’s relayer protocol
• Participating in technical specifications design, development, and implementations
• Upholding high-security standards and ensuring sound security practices when building out the protocol
• Collaborating with developers on all parts of the stack internally for auxiliary products such as wallets, block explorers, etc
• Performing and assisting engineers through code reviews, acceptance testing, bug fixing, and general support
• Staying up to date with emerging trends and applying them to Biconomy if applicable

Your experience should include:

• 4+ years of experience in software development and relevant experience in blockchain technologies.
• Practical experience with various consensus protocols/algorithms
• Practical experience with p2p communication in a decentralized network (concept of connecting to a peer node, handling connection drops, hands-on libp2p experience is a plus point!)
• Practical experience with designing and building high-performance and scalable network protocols
• Practical experience with mempool implementation (preferably EVM mempool) and ability to modify it as per network requirements. Non-EVM is a plus point!
• Hands-on experience with Go, Typescript, Nodejs, Javascript
• Hands-on experience with Oracles, Relayers, and setting up blockchain nodes
• Hands-on experience with Ethereum supplementary tools such as infura, ethers.js, hardhat, etc
• Demonstrated strong ability to take an implementation from POC to MVP to Production while ensuring quality

What’s in it for you?

You will get the first-row seat to designing and building the novel decentralized infrastructure that supports improved web3 UX through optimized transaction management and execution. You will have the opportunity to implement novel concepts and innovate on decentralized designs while also ensuring that we relentlessly ship products to production and not just implement them in silos.

More importantly, you get to be part of a team of highly experienced and driven individuals from around the globe to collaborate on and build industry-leading decentralized network infrastructure.

What we offer:

• Work from anywhere (Remote first)
• Flexible working hours
• Flexible vacation policy
• Competitive Salary
• Token Allocation
• Opportunity to grow. The sky’s the limit if you’re hungry to succeed
