Gyroscope is an all-weather stablecoin. It’s backed by a reserve portfolio that diversifies all DeFi risks - such as regulatory and governance risks - not just price risk. A Gyro Dollar can be minted for a price near $1 and can be redeemed for an amount near $1 in reserve assets, as determined through a new Automated Market Maker (AMM) design that balances risk in the system and concentrates liquidity around the $1 peg.

After a very successful testnet we are now looking forward to launching on mainnet.

We’re a team of around 6 and most of us are finishing or have completed PhDs in Computer Science and Mathematics. We are looking for a passionate smart-contract engineer to join us. You will be working closely with our other smart contract engineers to build and test Gyroscope’s smart contracts. We’re planning to release V1 in Q4 2021.

Blockchain Systems Engineer

Status is building the tools and infrastructure for the advancement of a secure, private, and open web3. 

With the high level goals of preserving the right to privacy, mitigating the risk of censorship, and promoting economic trade in a transparent, open manner, Status is building a community where anyone is welcome to join and contribute.

As an organization, Status seeks to push the web3 ecosystem forward through research, creation of developer tools, and support of the open source community. 

As a product, Status is an open source, Ethereum-based app that gives users the power to chat, transact, and access a revolutionary world of DApps on the decentralized web. But Status is also building foundational infrastructure for the whole Ethereum ecosystem, including the Nimbus ETH 1.0 and 2.0 clients, the Keycard hardware wallet, and the Waku messaging protocol; the p2p communication layer for Web3.

As a team, Status has been completely distributed since inception.  Our team is currently 200+ core contributors strong, and welcomes a growing number of community members from all walks of life, scattered all around the globe. 

We care deeply about open source, and our organizational structure has minimal hierarchy and no fixed work hours. We believe in working with a high degree of autonomy while supporting the organization's priorities.

# 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:
* Good understanding of process management
* Distros and package managers
* 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.
