Apie kompaniją

VaultSpeed builds software that speeds up data warehouse delivery. Its Data Vault platform automates data warehouse code generation, and its newer agentic AI platform lets data teams work with the platform through AI.

Darbo aprašymas:

– Build and extend the metadata engine. Implement new modelling and generation
capabilities in PL/pgSQL across our Data Vault layers. This is where most of the product’s
logic lives.
– Work on the code generation pipeline. Extend platform support, add generation features,
and keep the output correct and consistent across targets.
– Investigate and resolve customer-reported issues. Reproduce the problem, identify the
root cause and fix it. Analytical thinking matters more here than knowing our codebase on day
one.
– Test what you build. Test your own code and cover it with automated unit/regressions tests.
– Refactor and improve what’s already there. The product is mature and carries real history.
Part of the job is paying that down deliberately — simplifying logic, improving performance on
large models, tightening error handling — without breaking customers who depend on current
behaviour.
– Take part in review and release work. Review pull requests and support releases.

Reikalavimai:

– Strong SQL. You’re comfortable with complex queries — CTEs, window functions, recursive
logic, set-based thinking — and you can read a query someone else wrote and work out both
what it does and why it’s slow. Experience with stored procedures (PL/pgSQL, PL/SQL, T-SQL
or similar) is a significant plus.
– Solid Python. Practical, production Python: clear code, tests, type hints, packaging and
libraries.
– Strong analytical thinking. The ability to take a vague symptom, form a hypothesis, test it
against evidence, and arrive at a cause rather than a workaround.
– 3+ years of professional back-end or data engineering experience, including owning
features from design through to production.
– Experience working in a Scrum team — refinement, estimation, code review, and
communicating clearly about progress and blockers, across a distributed team.
– Git and pull-request-based development.
– Fluent communication in English.

Valuable, but you can learn it here:
– Data Vault 2.0, or another data warehousing architecture (Kimball, Inmon), and genuine
interest in the modelling problems.
– Experience with any of our target platforms: Snowflake, Databricks, BigQuery, Azure Synapse,
Microsoft Fabric, PostgreSQL, Oracle, SQL Server, Greenplum, AWS Redshift, SingleStore or
Apache Spark.
– ETL and orchestration tooling: dbt, Apache Airflow or Azure Data Factory.
– Code generation, template engines, parsers, or metadata-driven systems in general.
– JVM experience — some of our code runs on the JVM.
– Experience using AI coding tools such as Claude or Cursor as part of your daily workflow.
