Mission Statement

The additional yield that MEV provides has become a core part of staking returns, and the MEV-Boost architecture operates close to the core of the Ethereum protocol. The Aestus MEV relay was established by members of the Ethereum solo-staker community with one core mission: to improve economic decentralisation on Ethereum.

Aestus has been live on mainnet for 18 months and we are responsible for auctioning ~5% of Ethereum mainnet blocks. We’ve recently attracted community funding that provides us the opportunity to grow our team.

This is a competitive and dynamic environment where milliseconds matter. We are looking for a DevOps engineer whose primary responsibility will be to optimise our architecture with performance in mind. New ecosystem developments such as shared sequencing, and re-staking also present us with new opportunities - which you will have an essential role in exploring.

Summary of the Role

• You’ll be working in a small, friendly 3-4 person team with an opportunity to make your mark.
• Experiment with new technologies and make data-driven improvements to the performance, observability, and stability of our platform.
• Architect, configure and deploy global infrastructure on leading cloud platforms.
• Take responsibility for incidents and become a part of the on-call team.
• Engage in community discussions and contribute to the evolution of this ecosystem.

Qualifications

• A hacker mentality with substantial self-driven experience of linux sys admin, git, docker and k8s.
• Familiarity with common database technologies and networking protocols.
• Fluency in any of golang, python or rust.
• An understanding of the Ethereum staking and MEV ecosystem.
• A willing to get involved in novel technical challenges beyond a strict DevOps remit.

Benefits

• Remuneration dependent on skills and experience.
• Work from anywhere on a contract basis with flexible hours.
• Paid travel + expenses to Ethereum conferences and team meetups.

• $145k/yr salary for US-based candidates; $115k/yr salary for Canada-based candidates
• Fully remote work environment
• Health insurance
• 401(k) plan
• Macbook provided
• Home office budget
• Flexible vacation policy
• Learning budget
• Something missing? We’re small enough to try to make it work. Let’s chat!

• Engineers typically work on 1 to 2 engagements at a time in order to minimize context switching. Engagements often have multiple follow-on phases because we earn our clients’ trust.
• We have an async-first culture with few scheduled meetings and a lot of writing. We value deep work time.
• Sustainable hours. We are highly self-motivated folks, and we work really hard to meet our goals. But we value work life balance and know that fresh minds work better. Long or weekend hours are vanishingly rare here.

• Expand a complicated background process that synchronizes and normalizes data from multiple external data sources into a datastore that we control
• Build an admin UI that controls aspects of the data synchronization
• Estimate future projects. Evaluate which time estimates are risky and plan how to address the risk.
• Build a prototype to test functionality of an API for a future project
• Build a rich, interactive JavaScript UI that calculates the financial impact of an electric vehicle on a person’s electricity bill.

• Production experience with Ruby on Rails and React. 
• Strong project skills. Our small teams are so effective because we work together towards our goals. That means being responsible for hitting deadlines (or having the confidence to gently push back on them!) and helping our product team manage a project.
• Self sufficiency. You should have the ability to manage your own time, unblock yourself and unblock your team. That is not to say you should never get stuck! Part of self sufficiency is knowing when to raise your hand for help, and we like to help each other.
• A writer at heart. You enjoy communicating complex ideas via text. You proofread, even when sharing “rough drafts”.  You use writing to clarify your thinking.
• Curious tenacity. If you have to occasionally pull yourself out of a rabbit hole because a problem just won’t let go of your curiosity, then you’ll fit in here.

1. Fill out our application form at https://forms.gle/ePWjEcd1XQHXif3y7. If you email us, we'll likely miss it!
2. An Informal Interview (30 min) where we get to know each other and discuss expectations. If there’s mutual interest, we’ll ask you for a recent writing sample (something you’ve written previously about a complicated technical topic) and send a couple questions for you to answer in writing.
3. A Technical Interview (2 hours) where we code together in VSCode’s LiveShare. We will be collaboratively looking at problems inspired by things we actually work on – no bubble sorts or leetcode trick questions. You should have a clear sense of whether you’ll like working with us after we wrap up.
4. A Case Study (90 min) that seeks to simulate what it would be like for us to actually work together on a project, including a Product team member.
5. We’ll send you an offer within a week.
