Staff Software Engineer - Front end

We help people discover the magic of the perfect tutor, craft a personalised learning journey, and stay motivated to keep growing. 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. Joining Preply means helping define the future of education at global scale, and building something that truly matters for millions of people, every day.

At Preply, we build scalable and reliable applications using Python/Django, with a strong focus on data, A/B testing, and feedback from students and tutors to guide our decisions. We prioritize product quality through robust monitoring, metrics analysis, and continuous optimization. We are looking for a Staff Platform Engineer to be a high-leverage technical leader across the Platform Tribe. You will work across platform squads (Infrastructure, Runtime and Data, Developer Platform, Application Platform, Frontend Platform, Mobile Platform) to set technical direction, unblock complex problems, raise the quality bar through mentorship, and ship production changes hands-on.

Provide technical leadership across platform squads: architecture decisions, engineering standards, paved paths, and reusable patterns that reduce cognitive load and increase consistency.

• CI foundations, delivery workflow reliability, environments, and self-service entry points.
• Go deep on high-impact reliability and performance problems, including root cause analysis, remediation design, automation to prevent recurrence, and postmortem follow-through.
• Build and operate critical platform services and tooling that serve production traffic and internal users, with strong engineering quality and operational discipline.
• Act as a multiplier through mentorship: coaching senior engineers and tech leads, improving design quality, and raising execution standards across the tribe.
• Use data to guide priorities and measure outcomes (delivery health, reliability signals, adoption, and satisfaction), and help teams turn metrics into durable improvements.
• Participate in on-call and major incident response, leading by example and helping teams improve incident execution and prevention over time.

Strong track record as a senior technical leader (Staff or equivalent) delivering cross-team impact: setting standards, aligning stakeholders, de-risking complex technical decisions, and landing changes in production. Extensive hands-on experience designing, building, maintaining, and troubleshooting high-traffic distributed systems in production. Strong software engineering skills in Python / Django, with the ability to write production-quality tooling and services. Deep experience with DevOps and cloud infrastructure (preferably AWS): networking basics, identity and access patterns, infrastructure automation, and operational best practices. Strong foundations in reliability engineering: observability, alerting, incident response, capacity planning, and automation-driven prevention.

A generous monthly allowance for lessons on Preply. A competitive financial package with equity, leave allowance and health insurance. Access to free mental health support platforms. The opportunity to shape the lives of learners and tutors through language learning and teaching in 175 countries (and counting!).
