What you’ll be doing
As a Platform Software Engineer in the Developer Platform team, you'll build and operate the CI/CD systems, tooling and platforms that let Preply engineers ship quickly and safely. Build and improve CI/CD systems, testing capabilities, and paved paths that enable engineers to ship quickly and safely. Own and evolve the developer journey from writing code through testing and deployment. Build internal platforms, services, and developer tooling to turn developer experience friction into scalable engineering solutions. Provide the infrastructure and paved paths that let both engineers and coding agents build, test and ship autonomously. Use AI and agentic workflows to rethink and improve the software development lifecycle, and set up the quality gates and safety nets that keep them trustworthy. Operate what you build: take part in the team's support and incident rotation, and use data and developer feedback to measure and continuously improve the platform. Partner with engineering teams as the users of the platform, driving adoption of your tooling and aligning stakeholders across squads so changes land smoothly.
What you need to succeed
- CI/CD depth: strong hands-on experience building and operating CI/CD systems and pipelines at scale, including the reliability, performance and cost trade-offs that come with them.
- Extensive experience (~8 years) designing and building complex backend software systems.
- Software engineering skills, including Python, which we use to build platform services, developer tooling and automation. You do not need to be a Python-first backend engineer, but you should be productive in it.
- AI Expertise: You're a forefront user of Agentic AI. You're able to bring hands-on experience and start influencing the team beyond code generation; reserving judgment for architecture, business logic, and security, using AI as a thought partner and being able to set up quality gates and safety nets to enhance existing engineering workflows and propose AI-native alternatives.
- Experience building developer platforms, internal developer tooling, developer productivity or developer experience solutions.
- Experience designing platforms and tooling for engineers as internal users, with a strong understanding of developer needs and workflows.
- Familiarity with cloud-native environments and distributed systems.
- Business-orientation and data-driven approach.
- Strong communication skills.
- Minimum C1 English level.
Who you are
We are looking for someone who is collaborative, customer-focused, and thrives in a fast-paced environment with significant ownership and impact on architecture and decisions. You should be comfortable working with AI-native approaches and be able to influence beyond code into design and safety nets for engineering workflows.
Tech stack
Python for platform services, developer tooling and automation; cloud-native environments and distributed systems; AI/agentic workflows tools for software development lifecycle.
