About Longtail
At Longtail, we’re building an intelligent, autonomous decision-streaming platform for airlines. We combine scalable automation, proprietary algorithms, and contextual data to stream millions of real-time decisions directly into airline systems. Our platform lets airlines offer every possible travel product across their network—giving travelers more options on thousands of routes worldwide.
The Role
We are migrating from a small server farm in California to a modern, scalable cloud infrastructure. You’ll lead that transition—designing, implementing, and maintaining the systems that will carry our platform forward. This is a hands-on role that blends infrastructure design, automation, and reliability. You’ll work closely with the Engineering Lead (Barcelona) and core backend team to define a clear, reproducible foundation that scales globally. Your goal is to make infrastructure a product: reliable, observable, and easy for engineers to use.
In this role, you'll
- Lead the migration from four on-prem servers in California to a multi-region, cloud-based environment.
- Design and maintain CI/CD pipelines (GitLab CI, Jenkins, or CircleCI) for predictable, low-friction deployments.
- Build and manage infrastructure as code (Terraform preferred, CloudFormation optional).
- Containerize services and establish baselines for Kubernetes or equivalent orchestration.
- Implement and operate observability stacks (Prometheus, Grafana, ELK) to expose real system behaviour.
- Manage and optimize AWS (preferred) or GCP environments for scale, cost, and security.
- Support big-data infrastructure components such as Iceberg/Hadoop, and integrate them cleanly into the wider platform.
- Introduce self-service automation—tooling that enables developers to deploy and monitor systems independently.
- Collaborate with engineers to ensure new features are production-ready and meet operational standards.
- Define and document DevOps practices for the Barcelona base: environment setup, deployment rhythm, incident handling, and testing discipline.
Who You Are
- 8–12 years of experience in DevOps, Platform, or Infrastructure Engineering.
- Proven ability to move systems from on-premise or single-region setups to modern cloud architectures.
- Deep experience with AWS, Terraform, CI/CD tooling, and container orchestration.
- Skilled in Python or Bash scripting for automation and tooling.
- Strong understanding of networking, cloud security, and performance optimization.
- Experience operating or integrating with data streaming systems (Kafka, RabbitMQ) is a plus.
- Comfortable building infrastructure from scratch and improving it continuously.
- Able to bring the clarity and discipline of mature systems to a fast-moving startup environment.
- Practical, reliable, and steady under pressure—you own what you build.
Preferred Qualifications
- Experience in the travel tech industry or with airline systems.
- Familiarity with data streaming technologies such as Kafka or RabbitMQ.
- Certifications in AWS, Azure, or GCP.
- Experience with monitoring tools such as Prometheus, Grafana, or ELK Stack.
- Understanding of machine learning and data analytics workflows.
Why Join Us
You’ll design the infrastructure that underpins everything we build next. You’ll have direct access to the founders and Engineering Lead, clear accountability, and full technical autonomy. If you’re motivated by building systems that last—ones that combine reliability with speed—this role offers that balance.
We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses.
