If those describe you, this is the right opportunity for you!

Why are we awesome you ask?

We are truly at the forefront of the crypto ecosystem as maintainers of the infrastructure layer of blockchain networks! We practice the crypto team mentality by assembling a truly global and diverse team.

We collectively represent more than 12 different countries and are united in a single mission: building out the future of decentralization. Crypto is here to stay, having introduced novel ideas such as DeFi, NFTs and DAOs. At the core of all this are teams like us working relentlessly to build the necessary tools and applications that help run and secure blockchains.

Here are some other reasons you should join us:

• We have employees from over 10 countries across the globe, and you will be able to meet interesting people from different backgrounds and cultures. Distributed and remote work is baked into our culture.
• We are one of the top staking service providers with over $3B of assets staked across our validators. We actively explore and develop new products related to staking. You will work on high-impact engineering projects building exciting new products in a startup environment.
• We have a capable and passionate team. You will find teammates who are power DeFi users, intense NFT collectors, Bitcoin & Ethereum knowledge nerds, etc. You can learn and debate everything on crypto with our teammates.
• We are not backed by VC funding, and we are already profitable. Our financial independence means that we can make decisions independent of VCs, and we prioritize our ideals of decentralization, user sovereignty, and user privacy over simply making a profit. It also means that, unlike most other startups, stakefish can provide you with a stable low-risk employment opportunity without fundraising concerns.

The role

DevOps is a buzzword, but it’s also generic enough to encompass the breadth of tasks required in supporting development teams. There are many ways to make the lives of developers easier, and everyone has their own best way, which also means every team has their own way. There is no perfect way to make everyone happy with the same thing.

Supporting developers involves debugging obscure bash scripts from years ago that nobody remembers. It means biting on a piece of wood and using data formats turned programming languages like YAML to configure CI jobs. It means tracking down minute differences between releases of packages and libraries causing unexpected crashes. It means rewriting the same Dockerfile for the 5th time to allow a project to use one more obscure library. Or tracking down absurd race conditions of multi-threaded tests running in parallel on the same host. Or pulling your hair out at a bug only to realize it works fine after the CI worker host is restarted.

But fundamentally it means wrestling it all into submission and making it run smoothly… at least for as long as you’re there.

If you have the guts to fight against entropy and deterioration of the reality we inhabit, then you just might also be crazy enough to enjoy the struggle while it lasts, and appreciate the eventual fruits of our labour, if you value privacy, freedom, and transparency. You might even make some money, and learn a bit from all the exceptional engineers working here.

Who you are

You have strong Linux Fundamentals:

• Distros and package managers
• Good understanding of process management

You have programming experience:

• At least a few languages and showing the ability to learn
• Bash as a minimum; Python would be helpful

You have experience in Continuous Integration:

• Jenkins CI - Pipelines are written in Groovy
• GitHub Actions - PR builds, mostly

You have experience in Security:

• Good understanding of OpenSSH
• GnuPG for encryption of secrets and backups

Distributed Systems:

• Experience running Ethereum nodes
• Knowledge of Layer 2 scaling solutions

Compensation

We are happy to pay in any mix of fiat/crypto.

Hiring process

• Interview with the Talent team
• Paid task
• Technical interview with Head of Infra

[The steps may change along the way if we see it makes sense to adapt the interview stages, so please consider the above as a guideline]
