Backend Software Engineer

Your mission will be to develop and maintain a variety of software solutions, from internal scripting to complex SaaS platforms, in order to bridge the gap between software excellence and hardware performance within our sovereign cloud., * The Mix: Our team balances core Python development, complex React frontends, and automated IaC pipelines. You will work alongside peers who understand both code architecture and physical infrastructure constraints.

• How We Work: We run on a lightweight Scrum framework, prioritizing engineering excellence, clean design patterns, and high-impact project milestones.
• The Scaler Spirit: We thrive in a highly collaborative, international environment. We value open technical debates, continuous knowledge sharing, and giving every engineer the autonomy to shape the product.

YOUR DAILY ROUTINE

• Develop Core Product Features: Write clean, structured application code in Python to power our hardware update, testing, and inventory systems
• Own Your Domain (Frontend or DevOps): Depending on your track, you will either architect complex React/TypeScript admin interfaces or manage our Proxmox clusters, secrets, and automated deployments using Terraform and Ansible.
• Bridge Low-Level to High-Level: Work on a diverse codebase ranging from hardware-level data collection to web APIs.
• Drive a New Infrastructure Initiative: Partner with the team to design and ship the next major milestones of our next-generation architecture.
• Keep the Foundation Rock-Solid: Optimize, refactor, and test a significant volume of existing code to guarantee stability during long-running hardware validation tests.
• Maintain Engineering Excellence: Participate in rigorous peer code reviews, champion clean architecture, and engage in lightweight Scrum ceremonies (daily stand-ups, sprints, retros).

Strong proficiency in Applicative Python: You are a software engineer at heart. You care about clean code, architecture, testing, API design, and building robust backend systems. You have at least 4 years of experience writing structured application code.

• Your minor - Choose Your Secondary Strength (At least one): You don’t need to know our entire stack, but you should bring professional experience in at least one of these cross-cutting areas:

• The Frontend Track: Experience building highly responsive web applications using React and TypeScript. Proficient in modern state management and data-fetching patterns. Comfortable handling complex asynchronous states, long-polling, or real-time updates.
• The DevOps/IaC Track: Experience with Infrastructure as Code (IaC) and automation pipelines. Ansible and Terraform to provision virtualized clusters (Proxmox, …), building robust GitLab CI/CD workflows using Docker containers, and/or deploying/managing core APIs on Kubernetes. Orchestrating service VMs and automating system-level scripts or image builds is highly valued.
• Nice to have:
• The Systems Track: Solid foundations in Linux Sysadmin, networking protocols (VLANs, routing), bare-metal provisioning (DHCP, PXE, TFTP), or building custom Linux OS images (e.g., debootstrap/casper/mkosi). Bonus points if you’ve ever interacted with physical hardware labs or configuration management (like NX-OS).

WHAT IF YOU HAVE LIGHT/NO EXPERIENCE IN THE OTHER MINOR TRACKS OR DON’T KNOW THE SYSTEMS SIDE ? Apply anyway. We know this is a highly specialized stack sitting at the intersection of bare-metal hardware and cloud software. We do not expect you to be an expert in everything on day one. What we do require is intense technical curiosity.

SOFT SKILLS:

• Ability to work autonomously within a structured Scrum environment
• Highly involved, conscientious, and proactive in project delivery
• Excellent communicator with a collaborative “OneTeam” mindset
• Humble and open to constructive feedback
• Strong problem-solving and analytical thinking skills
• Continuous learner, eager to pick up new technologies and bridge technical gaps across our stack
