Software Engineer (AI)

Our client is a global smart-home security company (video doorbells, cameras, alarm systems) serving millions of households. And in the direction of improving customer support we build an AI-powered platform that processes 1,000+ customer-support conversations per hour. It detects the specific product problems customers face, links them to the right engineering tickets, and verifies with data whether each fix actually worked. We own its evolution end to end, with a focus on measurable results and an AI-first engineering workflow.

We are looking for a Software Engineer with solid experience building cloud-native services and data pipelines, alongside a proven track record of leveraging AI-driven development workflows.

In this role, you will take full end-to-end ownership of features - from analysing business requirements and reviewing real customer data to designing, building, testing, and deploying backend services on AWS. Additionally, you will work closely with product managers and cross-functional engineering teams to drive impactful solutions.

• The environment of equal opportunities, transparent and value-based corporate culture, and an individual approach to each team member
• Competitive salary packages with performance-based annual reviews.
• Opportunity to receive a Performance Bonus for your individual achievements and a Loyalty Bonus recognizing your dedication to the company.
• Employment via Contract of Employment (UoP) in complete alignment with Polish Labour Law.
• Guaranteed paid vacation, public holidays, and medical leaves as per statutory regulations.
• Continuous growth and development opportunities through internal knowledge hubs, corporate courses, and free English classes
• Comprehensive private medical insurance to supplement your standard NFZ coverage.
