Job Description:

We make decisions based on data, it’s the core of our business, and it’s providing insights into the effectiveness of our product and features. We believe data powers creativity and productivity, and that a robust, reliable and scalable infrastructure is needed to support this.

Our Observability team is operating the solutions that make gaining insights from data possible with monitoring, logging, metrics and other telemetry tools. The team is responsible for simplifying the process of building data and metrics-driven products and features. This is a high impact, high visibility role that directly affects the experiences of all our engineers.

As we take on more services and responsibilities, we're looking to add another member to the team.

What you will be doing:

• Design, build, and operate the observability stack of large-scale data infrastructure systems from the early stage
• Improve the stack, dive into new technologies and figure out how best to monitor them
• Provide easy ways to understand the state of the services at a given point in time, including the ability to trace requests across multiple services
• Work with development teams in an advisory capacity to optimize usage of monitoring and logging tools: what to log, measure and alert, which metrics and events are important and why through guidance, documentation and internal discussion
• Write well-crafted, well-tested, readable, maintainable code
• Participate in code reviews to ensure code quality and distribute knowledge, including Open-Source projects
• Mentor and guide junior engineers as the team grows

• You are knowledgeable about a variety of infrastructure and development topics
• You have worked in an environment that runs multiple services handling a large number of transactions, owned by different teams
• You have the skills to help a development team to perform complex debugging, but you also know when to let the team figure things out on their own
• You enjoy thinking about how to make life simpler for other engineers

The experience we are looking for:

• Designing, implementing and debugging large-scale data infrastructure systems, and identifying their performance bottlenecks
• Understanding of long-term impacts of key design decisions and handling failure scenarios
• Experience in Go is a big plus, but not strictly required and experience with a similar backend language would suffice. Our team can teach you and get you up to speed
• Monitoring and operating open source software in production at scale e.g. Kafka, Kubernetes, Docker
• Operating telemetry tools, e.g. the ELK stack, Prometheus, Grafana, Jaeger, Istio and others
• Not everything listed is required and not everything required is listed. If you have skills that are not listed but you think will contribute to your performance let us know!

What we offer:

• The chance to be be part of a growing team of with plenty of room to leave your mark and impact company strategy and growth
• Fun, creative and focused teams committed to learning and problem-solving through collaboration
• Competitive salary and, if required, visa sponsorship and a relocation package
• Office located in the heart of Berlin with teammates from around the world
• Time to work on projects that are not in the scope of the sprint, standing desks, team events and a weekly company dinner
• An environment in which you can balance great work with a great life

We value ownership and innovation, and we build our teams with that in mind. We want each team to be responsible and accountable for what they ship. We also don't want to reinvent the wheel every time, so we try to get alignment in terms of practices and technologies. Our philosophy to achieve this is relying on excellent tooling and automation over policies and processes.

Job Description

On the Nomad team, we develop tools for service deployment and batch job scheduling. Our customers place a high level of trust in us, relying on our tools to operate their own infrastructure and software effectively, and so we care deeply about reliability and performance.

This particular position is unique in that in addition to general Nomad backend engineering duties, this person will be the sole internal owner of the Nomad integration for Spark. We anticipate that work taking approximately 15-20% of this person’s time, and the rest of the time will be spent working on the overall Nomad roadmap along with the rest of the Nomad team. While we strive to hire at a variety of experience levels, this particular opening is not well-suited for recent graduates due to the level of independent ownership we expect for the integration for Spark. You will have the support of a Product and Engineering Manager in prioritizing and delivering work for the integration, but minimal fine-grained oversight from other Nomad Engineers. You will, however, benefit from direct interactions with users of the tool! This is an excellent technical leadership opportunity for someone with the capacity to operate well at this level of independence.

At HashiCorp, we value top-notch collaboration and communication skills, both among internal teams and in how we interact with our users. We take care to balance and be responsive to the needs of our open source community as well as our enterprise level customers.

Engineering at HashiCorp is largely a remote team. While prior experience working remotely isn't required, we are looking for team members who perform well given a high level of independence and autonomy.

In your cover letter, please describe why you're interested in working at HashiCorp, and what draws you to this role in particular! Since this is a unique role on the team, we require a cover letter for your application to be considered complete.

In this role, you can expect to:

• Be the sole internal owner of the Nomad integration for Spark
• Program in Golang for general Nomad work, learning from and contributing to a team committed to continually improving their skills
• Program in Scala for integration with Spark work, as an independent Scala expert
• Work on next-generation distributed systems for infrastructure management
• Develop novel algorithms within the context of our open source tools
• Build and architect systems for managing extremely large-scale global fleets of resources
• Interface directly with internal teams, users and HashiCorp customers, and represent HashiCorp well to the large Nomad community
• Own the full lifecycle of feature development from design through testing and release

You may be a good fit for our team if:

• You are fluent in Scala or a similar language (Java skills with an understanding of functional programming concepts is a workable substitute)
• You are interested in learning Golang if you aren’t already well-versed
• You have past experience working with large batch data workloads, and can empathize with the problems that Spark solves for its users
• You’re familiar with systems engineering, with networking and operating systems, and are comfortable with low-level programming
• You have prior experience working in high performance or distributed systems; while we strive to hire at a variety of experience levels, this particular opening is not well-suited for recent graduates
• You can knowledgeably discuss tradeoffs in distributed systems, such as those made for debugging and performance
• You're familiar with the pieces of typical modern infrastructure: secret storage, service discovery, etc
• You’re able to reason about performance, security, and user interactions in complex systems

At HashiCorp, we are committed to hiring and cultivating a diverse team. If you are on the fence about whether you meet our requirements, please apply anyway!
