PHP Developer | Email Team | Based in Lithuania

We're looking for a Backend Developer to join our Email team — the engineers behind one of the most enduring and underrated technologies in computing.

Email has powered communication for 50 years and it's not going anywhere. What is changing is the scale: our systems support 10 million+ mailboxes and handle massive request volumes every second. That's not a standard CRUD problem — it's distributed systems engineering with real consequences.

You'll design and maintain the APIs and backend services that keep those mailboxes running, working closely with the front-end team and other stakeholders to deliver a seamless experience.

Your day-to-day

• Architect, build, and maintain backend systems and APIs in PHP (with room to work in Go as you grow here)
• Define and optimize APIs for performance, scalability, and security — at 10M+ mailbox scale
• Own the data layer: schema design, query optimization, and ORM usage
• Integrate third-party services and keep documentation sharp
• Monitor and debug production issues before they become customer problems
• Write tested, readable code that moves the needle on real business metrics
• Raise the bar in code review and technical discussions with your teammates

• Strong PHP experience and solid command of OOP principles and design patterns
• Comfortable writing unit and integration tests as part of your normal workflow
• Hands-on experience with REST APIs, SQL, and at least one ORM
• Familiarity with message queuing (RabbitMQ, Kafka, or similar)
• Experience with Docker and containerized environments
• Understanding of microservice architecture

• 360 Growth: We provide limitless learning opportunities: access to platforms like Reforge and Coach Hub, global conferences, physical and digital libraries, feedback culture, and mentoring through TesoXchange. Advance your career with internal mobility and grow with a team eager to share knowledge and support your success.
• Freedom & responsibility: Work on your terms: from modern offices in Kaunas and Vilnius, the comfort of home, or anywhere in the world. Enjoy flexibility in managing your schedule and bring your ideas to life in a fast-paced, dynamic environment.
• Wellness simplified: Your health comes first with insurance from Day 1, gym memberships, recharge leave, Headspace subscriptions, and regular health checks. Join our wellbeing-dedicated events, sports, arts, and hobby clubs, or simply enjoy the balance of a lifestyle that prioritizes wellness.
• Work hard – play hard: Celebrate your achievements with company events like Summerfest & Winterfest, Town Hall, Meet the Client initiatives, team-buildings, and workations. Enjoy access to the Žalgiris Arena VIP Lounge and celebrate life’s big moments with milestone gifts for weddings, new parenthood, and graduations.
• Gross salary from 5600 - 7600 EUR/month. Specific compensation is offered based on work experience, competence and compliance with other job requirements.
• We’re always looking for experienced talent to raise the bar. If you’re excited about the role but the listed salary range doesn’t align with your expectations, we still encourage you to apply - we’re open to adjusting compensation based on the impact and value you bring.
