Come for the code, stay for the impact.

At Package.ai, we’re not just building software, we’re changing how retailers connect with their customers. From the first website chat to the final doorstep delivery and everything in between, we power meaningful, personalized journeys that keep people coming back.

With a platform trusted by over 100 retailers (and growing fast), strong product-market fit, and real momentum, we’re scaling up—and looking for a Senior Backend Engineer to help us take things to the next level.

Who you are:

What you’ll do:

• Design and build scalable backend systems that power real-time interactions.
• Take full ownership—from planning and implementation to deployment and monitoring.
• Work with a modern stack: Kotlin, AWS, Docker, Kubernetes, and more.
• Help shape the technical direction of a growing, product-led company.

What you bring:

• 4+ years of backend production experience with Kotlin, Java, Scala, Go (Kotlin is a strong plus).
• Solid hands-on experience with both NoSQL and relational databases.

• Bonus: familiarity with Rust, CI/CD, ML/NLP, or DevOps practices.
• Strong communication skills and solid English—written and spoken.
