Company mission
To empower developers to rapidly build and test their cloud applications, saving valuable time and resources.
Role
Who you are
- This role is ideal for someone with 5+ years of software engineering experience, strong API design skills, and solid backend expertise
- 5+ years (senior) of professional experience in backend or systems engineering, ideally within the database domain
- Strong understanding of modern databases and data warehouses, including SQL engines, query planning, storage layers, indexing, and SQL parsing/ASTs, with experience developing database features
- Hands-on experience with cloud data platforms such as Snowflake, Redshift, Athena, or BigQuery, including optimization techniques and custom parsers/transpilers
- Practical knowledge of distributed and analytical engines (e.g., Apache Spark, Trino, PostgreSQL, DuckDB) with skills in query engines, performance tuning, and integration in local and production environments
- Experience building developer tooling such as CLI tools, SDKs, and database drivers (JDBC/ODBC) or related integrations
- Proficiency in writing integration and regression tests, maintaining CI/CD pipelines, and automating test scenarios for complex data workflows
- Familiarity with Docker-based development environments (Docker & Docker Compose), containerized services for local testing, and container networking; Kubernetes experience is a plus
- Experience with at least one major public cloud (AWS, Azure, or GCP), ideally working with big data or database services
- Strong programming skills in Python (Java a plus); familiarity with TypeScript or Go is (nice to have.)
- Experience contributing to open source or working with communities to gather feedback, triage issues, and guide contributors. (Nice to have)
What the job involves
- You’ll work on Snowflake and AWS big data emulators, building features and ensuring high-fidelity cloud platform emulation to help developers test locally with speed and confidence
- Ensure Snowflake, Redshift, Athena, Glue, and future emulators are kept up to date with the latest syntax, behaviors, and APIs
- Identify and resolve bugs, edge cases, and inconsistencies across emulated services
- Maintain robust CI/CD pipelines, regression test coverage, and integration test suites for high-fidelity emulation
- Provide a fast and intuitive local development loop with meaningful error messages, good performance, and easy configuration
- Improve emulator usability in CLI tools, SDKs, and client integrations (e.g., JDBC, SnowSQL, 3rd part integrations)
- Design and implement support for additional data platform features, services, and cloud providers (e.g. Azure Synapse, BigQuery)
- Track cloud service evolution and update emulators to reflect new capabilities or changes
- Build abstractions that make it easy to plug in new service behaviour or data models
- Ensure emulators work seamlessly with orchestration and infrastructure-as-code tools (e.g., dbt, Terraform, Airflow, CDKs)
- Gather and act on feedback from internal and external teams to prioritize high-impact integrations
- Build usage analytics and telemetry to understand adoption patterns and developer needs
- Maintain high code quality, clear architecture, and extensibility to support contributions and experimentation
Our take
Developers can face high costs and delays with cloud-based testing (as centralised cloud environments are complex and expensive to maintain), which slows down development. This means that solutions to reduce these challenges are crucial for improving productivity.
LocalStack is solving this issue by providing a virtual environment that lets developers run a complete AWS setup on their laptops, cutting deployment times from 28 minutes to 24 seconds. It supports over 100 AWS services, reducing cloud costs and streamlining testing.
In an exciting move, the company raised substantial funding which will go towards expanding into the US and further developing its platform. With plans to offer new features like chaos engineering, LocalStack is ready to transform cloud development across multiple platforms.
