About StackGuardian

At StackGuardian, we’re on a mission to revolutionize cloud orchestration by building a scalable, secure, and developer-friendly platform. Our solutions empower organizations to deliver reliable software faster—without compromising on security or compliance. If you’re passionate about platform engineering and love being in the thick of coding, design, and leadership, we’d love to talk to you!

What You’ll Do

  • Lead by Example: Be a hands-on technical leader, contributing clean, performant code and architectural insights to our Python-based data and backend systems.
  • Build Foundational Data Systems: Design, implement, and optimize our core data platform, including building and maintaining our data lake/lakehouse/warehouse (e.g., using technologies like ClickHouse, Postgres, and Kafka or equivalents).
  • Establish Data Governance & Quality: Architect data pipelines using patterns like the medallion architecture (Bronze/Silver/Gold layers). Implement robust data quality, observability, and validation frameworks using tools like Great Expectations or similar.
  • Enable AI-Powered Products: Develop and maintain high-quality data flows and backend services that power AI agents and analytics features—from building feature stores to designing agent feedback loops.
  • Expand and Mentor: Help grow a team of backend and data engineers. Review code, set rigorous engineering standards, and encourage continuous learning and technical excellence.
  • Collaborate for Success: Work closely with Product, UX, frontend, and QA teams to deliver intelligent, data-driven features with a focus on security, scalability, and user experience.

Who We’re Looking For

  • Foundational Data Engineering Expertise: 4+ years of experience building data-heavy applications using Python (or Go). Deep, hands-on knowledge of designing, implementing, and optimizing data architecture components.
  • Data Lake/Warehouse/Lakehouse principles and implementation. Advanced ETL/ELT workflows and event processing systems (e.g., Kafka). Expertise in SQL and high-performance analytical databases (e.g., ClickHouse)
  • Experience with data quality frameworks (e.g., Great Expectations, dbt tests) and best practices like the medallion architecture.
  • AI & Analytics Awareness: Experience integrating with AI/ML models or agents, and a passion for building robust data platforms that enable intelligent decision-making and insights.
  • Leadership & Communication: Demonstrated ability to mentor team members, drive architectural decisions (especially related to data modeling and scalability), and communicate clearly with technical and non-technical audiences.
  • Cloud & DevOps Know-How: Proficiency with AWS (or similar), containerization (Docker/Kubernetes), and infrastructure as code (e.g., Terraform) to support scalable data deployments.
  • Product Collaboration: Comfortable working alongside product teams to shape roadmaps, align on priorities, and deliver features iteratively.

Why Join Us

  • Competitive Compensation: Attractive salary, plus equity options in an early-stage startup.
  • Influential Role: Shape AI solutions that form the backbone of our platform, directly impacting how enterprises adopt secure cloud practices.
  • Innovation Time: Dedicated hackathon and R&D days to explore your ideas and experiment with emerging technologies.
  • Culture of Autonomy: Enjoy minimal bureaucracy, flexibility, and the freedom to bring your vision to life.
  • Fast-Track Growth: Work alongside a dynamic leadership team, driving your professional growth in tandem with the company’s expansion.

Let’s shape the Future of Platform Engineering together!
