Job Description

You enjoy writing code, but in the back of your mind you’re always wondering: what problem does this solve? Who will be using this software and how will this make their work easier? You are fascinated by how your software is used and how it can be improved. You like to dive into the end users’ workflows to make them as seamless as possible. Because it’s not just about the code, it’s about the results.

You’ve found that having a robust, automated test suite frees the team to take on refactoring efforts with confidence, knowing that the system you’ve built won’t let you deploy broken software even if you try. You believe that collaborating with others makes it so that everyone learns, you build a better product, and you can sleep at night and go on vacation with the assurance that what you’ve constructed is stable.

Through the technology this team develops and runs, we're making onboarding of security tech unexpectedly simple for customers. We're also empowering our customer success team to onboard and maintain the fleet of our customers’ security devices, while being fully transparent with our customers with what we’re doing.

If this sounds like you, then we believe you'll love our team, and we’d love to talk to you!

What Expel Can Do For You

• Give you complicated, real world problems on which to use your skills and experience
• Develop your expertise in current technologies like Kubernetes, Kafka, Postgres, EmberJS and Go

What You Can Do For Expel

• Expand the core security device onboarding infrastructure our customers and analysts rely on 24 x 7
• Make sure our customer support staff have the tools that they need to fix problems with the array of customer security devices when they come up
• Enthusiastically reinforce our belief in good software engineering practice including code reviews and automated testing
• Add your viewpoint to our engineering culture (and especially this small team)
• Adapt to changes of direction because, hey, startup life!

What You Should Bring With You

• A desire and ability to constantly learn and improve yourself and your work products
• The ability to communicate and work effectively with others
• A track record of building maintainable systems in Linux environments
• Proficiency with at least one JavaScript framework (we use EmberJS but experience with another framework is valid)
• Proficiency with Go 
• Ideally: familiarity with cloud environments
• 3+ years of full-stack development experience

How We Run This Team

• We build and run teams where everyone is pulling in the same direction and is learning from each other:
• We work out of a shared backlog
• We peer-review everything
• We pair-program when it makes sense
• We do weekly blame-free retros to reinforce what’s going well, so we do more of it, and surface what’s not, so we can do something about it.

Additional Notes

At Expel, our employee benefits reflect our commitment to our crew. Unlimited PTO, equity for everyone, work location flexibility, up to 24 weeks of parental leave, and excellent health benefits are some of the ways we care for our Expletives.

Our headquarters is in Herndon, Virginia, however our team is fully remote, and we have full support for remote interaction. We realize that while there is benefit to in-person interaction, good people don’t all live in Northern Virginia.

We're only hiring those authorized to work in the United States.

We're an Equal Opportunity Employer: You will receive consideration for employment without regard to race, sex, color, religion, sexual orientation, gender identity, national origin, protected veteran status, or on the basis of disability.

We’ll ensure that individuals with disabilities are provided reasonable accommodation to participate in the job application or interview process, to perform crucial job functions, and to receive other benefits and privileges of employment. Please let us know if you need accommodation of any kind.

About Us

At Cloudflare, we have our eyes set on an ambitious goal: to help build a better Internet. Today the company runs one of the world’s largest networks that powers trillions of requests per month. Cloudflare protects and accelerates any Internet application online without adding hardware, installing software, or changing a line of code. Internet properties powered by Cloudflare have all web traffic routed through its intelligent global network, which gets smarter with every request. As a result, they see significant improvement in performance and a decrease in spam and other attacks. Cloudflare was recognized by the World Economic Forum as a Technology Pioneer and named to Entrepreneur Magazine’s Top Company Cultures list.

We realize people do not fit into neat boxes. We are looking for curious and empathetic individuals who are committed to developing themselves and learning new skills, and we are ready to help you do that. We cannot complete our mission without building a diverse and inclusive team. We hire the best people based on an evaluation of their potential and support them throughout their time at Cloudflare. Come join us!

In this role, you can expect to:

• Work on highly distributed and scalable systems
• Participate in the constant cycle of knowledge sharing and mentoring
• Manage and develop some of the biggest clusters in the world
• Research and introduce cutting-edge technologies
• Contribute to open-source

We are still a small team, well-funded, growing quickly and focused on building an extraordinary company. This is a superb opportunity to join a high-performing team and scale our high-growth network as Cloudflare’s business grows. You will build tools to constantly improve availability, performance, uptime and response times. You will nurture a passion for an “automate everything” approach that makes systems failure-resistant and ready-to-scale.

You may be a good fit for our team if:

• You have proven skills of designing, developing and delivering HA scalable production systems.
• You have deep knowledge of configuration management software, preferably Salt.
• You have solid experience with cluster management systems (Kubernetes, Mesos)
• You are comfortable with developing software in Go or Python
• You know how network services (DNS, TLS/SSL, HTTP) and network fundamentals (DHCP, subnetting, routing, firewalls, IPv6, BGP) work
• You have strong experience designing and managing multi-tenant database solutions (Clickhouse, PostgreSQL, CockroachDB)
• You are confident in your knowledge with load balancers (nginx, HAProxy)

Bonus points if:

• You have strong operational skills and are an expert in bash scripting
• You have practical knowledge of web and systems performance, extensively used tracing tools like ebpf and strace.

What Makes Cloudflare Special?

We’re not just a highly ambitious, large-scale technology company. We’re a highly ambitious, large-scale technology company with a soul. Fundamental to our mission to help build a better Internet is protecting the free and open Internet.

Project Galileo: We equip politically and artistically important organizations and journalists with powerful tools to defend themselves against attacks that would otherwise censor their work, technology already used by Cloudflare’s enterprise customers--at no cost.

Athenian Project: We created Athenian Project to ensure that state and local governments have the highest level of protection and reliability for free, so that their constituents have access to election information and voter registration.

Path Forward Partnership: Since 2016, we have partnered with Path Forward, a nonprofit organization, to create 16-week positions for mid-career professionals who want to get back to the workplace after taking time off to care for a child, parent, or loved one.

1.1.1.1: We released 1.1.1.1 to help fix the foundation of the Internet by building a faster, more secure and privacy-centric public DNS resolver. This is available publicly for everyone to use - it is the first consumer-focused service Cloudflare has ever released. Here’s the deal - we don’t store client IP addresses never, ever. We will continue to abide by our privacy policy and ensure that no user data is sold to advertisers or used to target consumers.

Sound like something you’d like to be a part of? We’d love to hear from you!
