About the Role: What's in the Box

HelloTech operates in autonomous, cross-functional alliances, each holding accountability for a specific product domain end to end. The service provider will join an assigned squad, with the flexibility to transition between teams and projects as technical objectives and business priorities evolve.

Several technical domains are actively engaging providers. Projects will be aligned based on individual strengths and expertise during the process. Key technical domains include:

• Marketing Customer Profile squad: Builds AI-powered backend systems that automate campaign execution end-to-end, from content generation and validation to multi-channel delivery across email, SMS, and push.
• Conversions Tribe: supporting the "Reachable Audience" and Personalization initiatives. The mission is to build the systems that power customized user journeys at scale.

Across all domains, the technical profile consists of highly available, event-driven distributed systems serving global architectures. This role does not include people management responsibilities.

What You’ll Do: The Recipe

• Maintain accountability for the architecture, design, development, deployment, and operation of microservices under a full DevOps model.
• Build event-driven systems utilizing messaging technologies such as Kafka, RabbitMQ, or AWS SQS/SNS, and expose data via clean REST and gRPC interfaces.
• Work extensively with Docker, container orchestration via Kubernetes, and CI/CD automated deployment pipelines.
• Maintain a strong commitment to testing, executing robust test suites stretching from unit tests through to full end-to-end coverage.
• Collaborate closely within cross-functional agile teams including product leads, frontend engineers, designers, and data teams.
• Provide technical guidance and support to surrounding team members, actively participating in code and architecture reviews.
• Leverage modern AI tools and workflows (e.g., Claude, Cursor) as a standardized component of engineering delivery to increase productivity.

What You’ll Bring: The Ingredients

• Senior-level expertise in at least one core language: Go or Python. High proficiency in one stack is required, with a willingness to expand technical knowledge into Go.
• Solid experience building, deploying, and operating critical backend services in a production environment.
• Technical comfort navigating distributed systems, messaging queues, containerization, and modern deployment infrastructure.
• Strong software engineering instincts, including practical application of design methodologies like TDD, BDD, or DDD, and the ability to make sensible technical trade-offs.
• Excellent communication capabilities to operate effectively inside an international, multi-disciplinary technical environment.

What We Offer: The Toppings

• Global collaboration at scale: Collaborate with experienced engineers and product partners across HelloTech’s international teams, in a culture of active knowledge sharing.
• Technology with real-world impact: Build and operate modern systems at global scale, supporting millions of customers and complex supply chain operations.
• Technical/Product/Design leadership: Drive best practices and influence architecture/design, quality, and ways of working in an autonomous, product-led setup.
• End-to-end development/delivery: Drive decisions from problem definition to production, improving systems and enabling long-term scalability.
• Access to workspace at Warsaw Centre Point: The hub offers modern facilities including showers, breakout zones, outdoor space, cycle parking, and refreshments (coffee, soft drinks, and fruit).
