We power people’s progress.
At Preply, we’re all about creating life-changing learning experiences. We help people discover the magic of the perfect tutor, craft a personalised learning journey, and stay motivated to keep growing. Our approach is human-led, tech-enabled — and it’s creating real impact.
We’ve just reached unicorn status with a $150M Series D, accelerating our vision to transform education through human-led, AI-enhanced learning. Today, 100,000+ tutors teach 90+ languages to learners in 180 countries — and we’re only getting started. As a category-defining company, we’re shaping what the future of learning looks like at global scale.
Every Preply lesson sparks change, fuels ambition, and drives progress that matters. Joining Preply means helping define the future of education at global scale, and building something that truly matters for millions of people, every day.
Meet the team!
The Platform Tribe builds and operates the platform that Preply engineers develop and deploy on, and that millions of learners and tutors rely on every day. Our platform handles over 20bln requests per month, and we combine software engineering, distributed systems and cloud infrastructure to keep it reliable at scale while making it faster and easier for engineering teams to build on top of it.
As part of the SRE team, you’ll focus on:
Reliability at scale: maintaining high availability while traffic continues to grow.
Platform scalability: evolving the systems that support Preply as our product and engineering organisation grow.
Developer productivity: building core services and tooling that help engineers ship safely and quickly — we run 100+ successful production deployments every business day.
Efficient infrastructure: improving performance and reliability while making thoughtful FinOps trade-offs.
We work in small teams with significant ownership, so you’ll have a real say in architecture, technical decisions and how our platform evolves.
We have diverse technical challenges that will allow you to develop your skills across the stack — sometimes we write about them in our Engineering Blog! Please, also visit our Tech Radar and our YouTube channel to learn more about the technologies we use at Preply!
What you’ll be doing:
The Senior Platform Software Engineer role in our SRE team combines software engineering practices with cloud infrastructure, distributed systems patterns, storage systems and observability to deliver on a wide range of projects — ranging from tooling to core Platform services which serve production traffic.
Own the availability and performance of mission-critical services and build automation to prevent problems recurrence.
Improve the system’s scalability, observability, and alerting.
Build tooling to improve our platform and accelerate the overall software development.
Practice sustainable incident response and blameless postmortems.
Collaborate with product teams to help them tackle technical issues and design new systems.
Strengthen credibility with the quality of the team’s technical execution.
Follow the best FinOps practices.
Participate in on-call rotation across the team.
What you need to succeed:
Extensive experience (~8 years) in designing, building, maintaining and troubleshooting high traffic distributed systems.
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.
Proficient software engineering skills (Python preferred).
Experience with at least one major public cloud, its services and infrastructure (preferably AWS).
Experience in implementing observability and alerting.
Willingness to participate on paid on-call rotations.
