Job Details

What you will do

Location: remote
Position: full-time

Erigon is an Ethereum (also Gnosis Chain and Polygon) Execution Layer on the efficiency frontier. It's written in the Go programming language. We've been innovating in space- and time-efficient ways of doing blockchain execution and data. Further information about Erigon is available at https://erigon.substack.com.
Erigon is looking for senior/intermediate-level developers, preferably with core blockchain experience. If you enjoy solving challenging technical problems and want to scale blockchain to billions of users, this is a perfect opportunity!

What you will do:

Grasp complex technical topics such as Ethereum protocol changes (e.g. EIP-7002) as well as algorithms and data structures non-specific to blockchains.
Understand scientific papers like "RecSplit: Minimal Perfect Hashing via Recursive Splitting", https://arxiv.org/abs/1910.06416.
Work with other teams (Ethereum Foundation researchers, other L1 developers, and the broader community) to implement experimental EIPs (say, EIP-3074) in Erigon and provide critique and feedback on such EIPs.
Persevere through a somewhat messy code base and ultimately simplify and improve it.

Who you are

Main requirements:
- Potential candidates should be talented software engineers capable of handling complicated code and technically challenging problems.
- Competence in Computer Science (performance characteristics and applicability of algorithms and data structures).
- Knowledge of how the blockchain technology works at the fundamental level.
Desirable, but not mandatory requirements:
- General knowledge of the Go programming language and its internals.
- Advanced mathematical knowledge, for example, of elliptic curve cryptography or Byzantine fault tolerance.
- Knowledge of DBMS data structures such as B-trees and LSM trees.

What we can offer you

Erigon will provide you with help and guidance, as well as sufficient time to learn, so that you can effect complex code changes productively. At the same time, we expect you to be proactive with your tasks and work independently, asking colleagues for assistance when necessary. Ultimately, you should be able to deliver without being micro-managed.
Flexible working hours. Virtually no mandatory team meetings.
Flat hierarchy with zero bureaucracy. Erigon's founders are software engineers.
Opportunity to work on challenging programming, algorithmic, or cryptographic problems on the bleeding edge of what is technically possible.
