Job description

We’re looking for a Senior DevOps Engineer to join our SRE team within our Infrastructure & Production group. Site Reliability Engineering (SRE) is responsible for our infrastructure development and maintenance. Our architecture consists of both cloud and bare metal solutions.

We believe in automating our infrastructure as much as possible and pursuing challenging problems in a sustainable and repeatable way. Currently, our infrastructure processes petabytes of data every month through thousands of servers and we are moving towards a Hybrid Cloud environment where we utilize the best of both worlds to build scalable production and development environments. Our team utilizes SRE and DevOps principles as our way of working.

Our toolchain

• Hybrid Cloud: 2500+ dedicated servers, supplemented with a mix of private and public cloud
• Infrastructure as code: Ansible and Terraform and AWS CDK
• Kubernetes “the hard way” on 2000+ dedicated servers
• We also run supporting infrastructure like PostgreSQL, MongoDB, Cassandra, ElasticSearch, VictoriaMetrics, HAProxy, Clickhouse, Aiven, Kafka and more

We are currently working in a hybrid mode where the team visits the office three days a week.

You'll need:

• Production experience with distributed/scalable systems and/or high traffic web applications
• Experience in running large scale production with Kubernetes
• Experience working with public cloud environments, preferably AWS
• Experience with configuration management systems such as Ansible
• Extensive knowledge of the Linux operating system
• Troubleshooting skills that range from diagnosing low-level OS issues to large-scale failures within distributed systems
• Knowledge of how the web works and HTTP fundamentals
• Knowledge of IP networking, DNS, load balancing and firewalling
• Knowledge in good security practices, including network security, system hardening, secure software
• Ability and willingness to work three days a week in our Helsinki office

Bonus points, if you have:

• Good knowledge of at least one programming language. Smartly uses e.g. Python, Ruby, and NodeJS
• Experience in containerising applications and deployment to production (Docker, Kubernetes)
• Experience in building large scale modern infrastructure in cloud environments (AWS, GCP, etc)
• Experience in SQL, building complex queries and debugging query performance
• Experience with SQL databases like PostgreSQL, NoSQL stores like Redis or anything in between
• Familiarity with automated build pipelines, continuous integration, delivery and deployment. Currently we’re deploying to production ~2000 times/week
• Experience building large-scale data processing pipelines

What We Offer You:

• Inclusive Culture: Join a team of over 800 Smartlies representing more than 60 nationalities across 24 locations in 13 countries, we foster a culture built on trust, transparency, and open feedback
• Global Impact: Be part of a company making a global impact, directly influencing our customers and business growth
• Wellbeing Focus: Enjoy generous healthcare packages, mental health services, and a healthy work-life balance with paid holidays and family leave
• Total Rewards: Benefit from equity options, performance-based rewards, competitive compensation, and ample career development opportunities
• Hybrid Workplace: We work in a hybrid model, balancing office and remote work, with the option to work abroad for up to 30 days
