Software Engineer, Core SRE
- Lisbon, Portugal
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 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.
