Who We Are

At Deckard Technologies, we're not your typical GovTech company. We're a global data company helping local governments solve real-world property challenges such as boosting tax collection and improving compliance with cutting-edge tech.

With patented processes, intuitive AI, and over 400 jurisdictions trusting our platform, we're transforming the way cities and counties manage the places people call home.

We're a passionate team spread across the US, Colombia, and Australia, united by our love of smart data and practical impact. When you join Deckard, you're stepping into a collaborative, down-to-earth, and ideas-first culture where your voice matters and your work genuinely makes a difference.

About the Role

We're looking for aPrincipal Full Stack Developerto work on core parts of our platform, from backend APIs and data services to frontend components and dashboards.

You'll be hands-on in building features, refining architecture, and tackling performance and scale challenges across a platform that processes large volumes of property and geospatial data. You'll collaborate closely with development, data science and product teams to ship reliable, maintainable software in a fast-paced environment.

This role is ideal for someone who wants to stay deep in the code while contributing meaningfully to architectural decisions and technical direction.

What You'll Be Doing

  • Design and build backend services and APIs using Python, Flask/FastAPI, and GraphQL.
  • Develop modern frontend interfaces using React and TypeScript.
  • Write clean, testable, production-quality code that holds up under scale.
  • Work across cloud-native data processing tools like Spark, Athena, and Glue.
  • Improve platform performance, reliability, and observability.
  • Contribute to infrastructure-as-code and CI/CD workflows.
  • Debug complex problems across the stack and production environments.

What We're Looking For

  • 8+ years of experience in software engineering, with deep exposure across the stack.
  • Proficient in Python and familiar with building REST or GraphQL APIs.
  • Practical experience working with Snowflake and understanding of its architecture and SQL model.
  • Experience working with big data tooling (e.g. Spark, Presto, S3, Athena).
  • Familiarity with cloud infrastructure (AWS preferred) and infrastructure-as-code practices.
  • Skilled in writing automated tests and working within CI/CD pipelines.
  • Comfortable navigating ambiguity, asking questions, and figuring things out independently.
  • Strong grasp of performance, security, and maintainability concerns in production systems.

Nice to Have

  • Experience with GraphQL (Apollo Server/Client).
  • Familiarity with containerisation and orchestration (Docker, ECS, EKS).
  • Exposure to analytics-heavy platforms or map-based UIs.
  • Interest in property data, government systems, or civic tech.

Why You'll Want to Work Here

  • Work on software that helps governments fund public services and catch fraud.
  • Tackle meaningful engineering problems with real-world impact.
  • Build and ship features without layers of red tape.
  • Collaborate with a skilled team that values autonomy, focus, and clarity.
  • Enjoy a hybrid work setup with flexibility and autonomy

If you're an experienced developer who cares about building fast, clean, reliable systems and you're ready to own meaningful pieces of a growing platform we'd love to hear from you.
