This job posting is no longer available

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!

Job Description

Our true purpose at Castor

Castor is one of the leading platforms for data collection in medical research. We believe standardizing and reusing datasets is key to overcoming the healthcare challenges of the future.

How we operate

Our main Electronic Data Capture (EDC) application runs on a proven stack consisting of Ubuntu, Nginx, PHP and MySQL. For our cloud installations, we orchestrate these setups by using Terraform combined with Ansible for the server configuration management.

Due to the nature of processing medical data, we have clients in different regions across the globe, often with specific regulatory constraints around where and how their research data is stored. To meet these customer demands we combine both traditional as well as cloud-based hosting solutions.

Most of our clients prefer to run in Azure, but we’re using Google Cloud Platform for things like Kubernetes hosting of greenfield projects, blob storage for scalable file upload storage and their Key Management System (KMS) to further secure our data.

For our metrics we’ve begun standardizing on Prometheus and we’re moving towards Loki for log aggregation. We use PagerDuty for alerting, communicate via Slack and host our code on Github.

Why we’re growing our team

With our recent expansion have come new challenges, both in how we organize ourselves and in how we manage and scale our infrastructure in the future.

To further these efforts we have formed a Platform team consisting of SRE and Software Engineering, which we are now looking to grow with the addition of an additional SRE.

Additionally, due to the sensitive nature of medical data, Castor is certified for both ISO/IEC 9001 (quality) and 27001 (Information security). In addition, we have to adhere to a number of other regulations, including Good Clinical Practice (GCP) guidelines.

Our goal is to unite these requirements with emerging SRE practices around infrastructure as code and other principles to create a well designed and documented system, while still allowing us to remain flexible to change.

How you will contribute

Our absolute commitment to patient data security and privacy informs our vendor selection with certified datacenter and cloud providers. To achieve real impact in medical research, Castor needs to operate security around the world.

Historically, our production platform has run on top of managed hosting services. This model doesn’t scale well for our global, international footprint, which is why we are currently expanding our in-house knowledge and transitioning to Infrastructure-as-a-Service providers.

As a Site Reliability Engineer, you’ll have the ability to shape our operations and continuously deliver a working product. Working very closely with the development teams, you’ll collaborate in supporting and structuring our efforts around automation, observability and security. With your help we plan to scale the Castor platform to the next level.

Some things we worked on recently

Whilst there are many operational challenges as we continue to grow and scale at Castor, our Platform team has made great improvements to a variety of our systems already. To give you some examples of what we achieved last month:

  • Migrated our DNS to AWS Route53
  • Set up automatic documentation pipelines using MkDocs
  • Moved our CI/CD pipelines from Jenkins to CircleCI
  • Built a key-service on AWS Lambda to store disk encryption keys off-site for an otherwise region-local setup

Your background

You have helped run web-facing services under production workloads and have experienced the challenges that come with maintaining and scaling these systems. Making and owning decisions about systems architecture together with your team is something you enjoy and feel comfortable with.

Qualities we’re looking for include:

  • A good grasp on how *NIX systems operate
  • The ability to evaluate and implement best practices for IT operations
  • A working knowledge of both cloud-native and traditional systems architecture and the trade-offs between them
  • Experience with a configuration management framework such as Ansible, Chef, Puppet or SaltStack
  • The ability and desire to work with a wide range of open source technologies
  • A strong privacy- and security mindset
  • Experience with some aspects of Observability and distributed systems: from monitoring, logging and metrics instrumentation to resiliency to failure
  • A good understanding of how relational databases operate
  • Experience with at least one programming or scripting language, preferably Python or Go(lang)
  • Knowledge that a list of skills and requirements doesn’t mean you have to tick every single box to apply ;)

How we say thank you

At Castor we truly live our core values, believing we can achieve anything with a healthy and happy team. With this in mind, we offer the following benefits:

  • Our own ‘Castor Burrow’ - brand new offices by Amsterdam Amstelstation
  • A competitive salary plus an annual company bonus plan
  • Employee Stock Option Programme incentive
  • 30 days annual leave plus 6 public holidays
  • An individual training and professional development budget
  • Flexible working with the opportunity to work from home 1 day per week
  • Meditation room with daily yoga, mindfulness and company subscription to Calm
  • Lunch and healthy snacks in the office every day
  • A new Mac or Dell laptop
