Devops Engineer at Sigp

In order to improve coverage of a round-the-clock devops team, we currently have a strong preference for a candidate that can work in an Americas timezone. The ideal candidate should have: 1. Kubernetes and terraform experience - Competent with Kubernetes architecture (e.g., pods, deployments, services, and stateful sets). - Familiar with Kubernetes networking (e.g., service discovery, ingress, overlay networks). - Competent with leveraging CI/CD pipelines to deploy containerized applications to Kubernetes. - Competent with Kubernetes administration tasks (e.g., scaling, rolling updates, rollbacks). 2. Blockchain experience - Competent with blockchain data structures (e.g., blocks, forks, etc). - Competent with blockchain signature schemes (e.g., high-level understanding of ECDSA). - Competent with blockchain P2P networks (e.g., high-level understanding of peers and how they are discovered). 3. Linux experience - Highly competent with the Linux shell. - Highly competent with systemd, journald, etc. - Highly competent with server security concepts (e.g., firewalls, public key authentication, vulnerability patching etc.). - Highly competent with networking fundamentals (e.g., subnetting). - Competent with DNS and managing domains. 4. Ansible experience - Competent with Ansible workspaces, playbooks and other core concepts. - Competent with the Jinja2 templating language. - Competent with building and maintaining YAML documents. Candidates with extensive devops experience but little blockchain experience will be considered. Candidates who cannot demonstrate an interest in Ethereum need not apply, enthusiasm is critical. Candidates must be self-driven and motivated to learn about and improve the systems around them. We provide high-level strategic guidance and constructive feedback, however we do not micro-manage our team members. Candidates are responsible for their own day-to-day activities. Candidates should be willing to rotate being "on-call" for response to infrastructure issues and outages. Candidates must be proficient in technical conversations in English, both written and verbal. Perfect English is not a requirement, accents keep things interesting :) No jerks, trolls or bullies. THE ROLE To work alongside and assist developers in building core decentralised network infrastructure. The nature of our work requires small-scale and large-scale network testing and monitoring. As a devops engineer, your role will be to create testnets, devnets, tooling and monitoring systems to help developers identify issues and verify software implementations in a variety of network conditions. In addition, we run high-performance production instances of our software which require maintenance, monitoring and a very high standard of security practices and processes. Apart from assisting developers, building and maintaining production infrastructure, we hope the candidate has an interest in improving current designs. We always welcome new ideas, practices, tooling improvements and offer time for the candidate to find new and improved ways of improving our devops infrastructure. The current tooling relies heavily on Ansible, Kubernetes, Terraform and testnets are now favouring Kurtosis. Experience with all of these technologies is not required but is favourable. LOCATIONS The candidate is free to choose between being remote or local in Sydney. Remote work is an essential part of our company culture. Those who work remotely still form an integral part of the team. THE COMPANY Sigma Prime was established in 2016 and provides information security and niche development services to some of the biggest names in Ethereum and DeFi. Lighthouse [Upgrade to PRO to see link] our Beacon Chain implementation, is a key piece of Ethereum infrastructure. Our engineers have world-class knowledge of Ethereum staking and maintain high performance validators across several testing and production environments.
