Sr. IT Developer at ExtraHop
Seattle, WA, US

We’re growing, and we’re looking for people who love to build things: products, companies, markets, and their careers! Are you an engineer who loves to create a solid operational foundation, but also enjoys solving fast-moving and emergent needs? Let's meet.

What does IT at ExtraHop look like?
As part of the ExtraHop IT (EHIT) team, you will be designing, maintaining, and occasionally breaking our customer-facing and internal systems. Our needs are fast-moving, and we understand managed risk. We are a close-knit and mutually supportive team with an emphasis on cross-training and sharing. Duties often overlap and flow, even across team boundaries.

We follow principles aligned with DevOps methods to ensure agility while anticipating future needs to reduce waste. Home-grown software is predominantly in Python 3 and Shell, with exceptions as appropriate. We version control all the things, prefer serverless when we can, containers when we can't, but we don't shy away from doing it old school when the need fits.

Duties and Responsibilities:
  • Ensure 24x7 responsiveness of services and infrastructure, including on-call rotation for production services.
  • Design and manage the monitoring of production systems, using both ExtraHop wire data products and conventional tools.
  • Add to our internal and user-facing knowledge bases, including design documents, playbooks, diagrams, and documentation.
  • Design and construct secure, future-proof hybrid, multi-cloud networks.
  • Implement and improve human and automated workflows for operations and support.
  • Write elegant, extensible, sustainable code to solve current and future problems as simply as possible, but no simpler.
  • Learn and grow as an engineer and as a colleague.
Required Qualifications:
  • 8+ years in Unix/Linux systems administration and software development.
  • Experience using Python, Shell/Bash, and one or more other languages to solve problems in a Linux/Unix environment.
  • Comfort with a distributed version-control workflow in a team setting.
  • Competency with web infrastructure operations and development/deployment.
  • Interest in or familiarity with cloud and serverless infrastructure.
  • Experience with one or more virtualization platforms (e.g. Linux KVM).
  • Knowledge of essential enterprise networking and application protocols: TCP/IP, HTTP, SSH, DNS, LDAP, TLS.
  • A basic appreciation of data and database management principles and methods. Some understanding of the differences between relational and object data stores.
  • Demonstrated ability to manage a deep stack of context frames, and you understand what that means.
  • Well-practiced collaborative skills, including verbal and written communication.
  • Self-directed problem-solving capacity; able to explain choices while building consensus with peers and partners.
  • A security-oriented mindset in all operational matters.
  • Opinions! The best engineers have well-formed points of view even when they disagree collegially with their peers. It is okay to like emacs if you can discuss it with someone who prefers vi.
  • Unafraid of the unknown: you are always ready to jump into the abyss, to discover, and to build.
Skills and Experience:
  • Cloud virtualization platform background: AWS, Azure, or GCP.
  • Firewall and security management.
  • Helpful secondary languages: JavaScript, SQL, Go.
  • A good understanding of virtualization and container technology abstractions.
  • Knowledge of secondary networking and application protocols such as UDP, SMTP, NTP, SNMP, Finger.
  • Linux configuration management systems implementation and configuration such as Ansible, puppet, or chef.
  • Experience with cloud-based databases or warehouse solutions such as Snowflake, AWS RDS, DynamoDB, Azure SQL Server.
  • Thoughts on the Oxford comma and double sentence spacing.
