Are you ready to help shape the future of AI with agentic, production-ready solutions? Join us in a dynamic environment where your curiosity and DevOps mindset fuel the next generation of GenAI innovation! As a Software / Platform Engineer, you’ll have the opportunity to design, build, release, and maintain cutting-edge applications and platforms, all while collaborating with experienced mentors and making a tangible impact on our technology’s evolution.

What you are going to do

As a Medior Software / Platform Engineer, you will be actively involved in designing, building, releasing, and maintaining our cutting-edge GenAI platform that leverages agentic capabilities. Operating in a DevOps environment, you’ll take ownership of your work end-to-end—from concept and architecture through production deployment and ongoing support. Your skills in Python, microservices or SOA, and SOLID principles will help our team create robust, scalable, and secure solutions that push the boundaries of AI innovation, while your platform engineering expertise in Azure, Terraform, CI/CD, and networking will be vital in ensuring the platform's reliability and performance.

In this role, you’ll collaborate with cross-functional teams, including Software Engineering, Data Science, and Platform Engineering, ensuring our solutions evolve to meet the dynamic needs of both internal and external stakeholders. You will also learn from and work alongside senior team members, adopting best practices to develop and maintain high-quality AI-driven applications and platform infrastructures under an Agile framework.

Key Responsibilities:

• Contribute to the end-to-end design and implementation of our agentic, production-ready GenAI platform, bringing innovative ideas from concept to deployment
• Design and maintain service-based solutions (microservices or SOA) in Python, applying SOLID principles to ensure clean, maintainable, and extensible code
• Develop and maintain CI/CD pipelines using tools like Azure DevOps or GitHub Actions, ensuring rapid, reliable releases and leveraging observability to gain real-time insights into system performance
• Implement and manage Infrastructure-as-Code (IaC) using Terraform or ARM templates to ensure consistent, secure, and efficient cloud resource provisioning on Azure
• Engage in Agile ceremonies and collaborate with cross-functional teams to iterate quickly, deliver impactful features, and continuously improve development practices
• Share and implement secure, scalable, and cost-efficient best practices across the platform, ensuring reliability and resilience
• Participate in code reviews, learning from experienced engineers and contributing to a collaborative environment that promotes knowledge-sharing
• Assist in troubleshooting, optimizing, and refining system performance through observability tools and dashboards to ensure a seamless user experience
• Stay informed of emerging technologies and industry trends, proposing enhancements to our GenAI product roadmap and platform capabilities

Who you are

You are a proactive, self-driven engineer with a passion for technology, mentorship, and collaboration. You continuously build upon your expertise to drive innovation and elevate team performance. Your personal qualities and skills include:

• 4–6 years of professional software engineering experience, including 2–3 years building production back-end services in Python and familiarity with at least one other language (Go, Java, TypeScript, etc.)
• Hands-on experience developing and maintaining microservices / SOA back-ends (REST, gRPC, or event-driven), supporting moderate traffic and uptime requirements
• Practical exposure to GenAI or large-language-model features (e.g., calling Azure OpenAI APIs, basic prompt design, integrating vector stores) and enthusiasm to deepen this expertise
• Working knowledge of key Microsoft Azure services—Blob Storage, Azure Container Registry, Functions, AKS, and Virtual Machines; prior use of AI Foundry or Azure OpenAI is a plus
• Comfortable containerizing applications and deploying them to Kubernetes (AKS/EKS/GKE) or Docker-based environments; able to create or modify Helm charts / manifest files
• Capable of reading and updating Infrastructure-as-Code templates (Terraform or Bicep/ARM) and applying basic policy guidelines to keep cloud environments consistent and secure
• Experience configuring CI/CD workflows with YAML-based pipelines (e.g. GitHub Actions, Azure DevOps or GitLab CI), including automated testing and simple security scans
• Familiarity with observability practices—instrumenting metrics, logs, or traces and using tools such as Prometheus/Grafana, Datadog, or Azure Monitor to diagnose issues
• Proficient with at least one SQL and one NoSQL datastore (e.g., PostgreSQL, MySQL, Cosmos DB, MongoDB) and understanding of message queues or pub/sub systems (Kafka, Event Hub, SQS)
• Knowledge of secure coding and cloud-security basics (secret management, least-privilege IAM, OWASP)
• Applies SOLID and clean-code principles, participates actively in code reviews, and collaborates well with teammates to deliver high-quality features
• Able to prioritize work and communicate effectively with stakeholders
