Job Description
Massive Rocket operates as a rapidly expanding agency specialising in Braze and Snowflake, aiming to reach $100M in revenue while connecting digital marketing, product, and engineering teams. The organisation is hiring a Software Development Engineer in Test (SDET) on a fixed-term contract basis to work remotely. This role suits an engineer who enjoys building automated testing frameworks from scratch, solving intricate data challenges, and safeguarding the reliability of a complex data ecosystem.
As the engineering gatekeeper of the core stack—which includes Databricks, mParticle, Braze, OneTrust, and ThoughtSpot—the person in this position will write code to test code rather than checking files manually. Responsibilities include building validation frameworks, simulating user behaviors across platforms, mocking cross-platform API integrations, and collaborating with Data Engineers to resolve pipeline failures and maintain data hygiene.
Responsibilities
- Design and implement automated validation frameworks to test data contracts, schema compliance, and identity resolution logic in Databricks
- Build and maintain automated UI and behavioural test scripts simulating customer journeys across web and mobile applications
- Verify programmatically that behavioural events, mParticle tags, and OneTrust consent tokens fire accurately at the application layer
- Validate high-criticality data flows through the Databricks, mParticle, Braze, and OneTrust ecosystem
- Write automated integration scripts and mock API payloads to verify action propagation and user suppression or activation across platforms
- Design and execute end-to-end tests for data collection pipelines including point-of-sale, web, app, and CRM sources
- Check data freshness and latency against near real-time service level agreements
- Establish automated rules to detect corrupted records and schema drift in near real-time
- Audit data flows to ensure strict adherence to global privacy regulations such as GDPR and UK GDPR
Requirements
- Demonstrated mastery of SQL for complex data validation and anomaly identification across millions of records
- Proficiency in Python for constructing automated test suites and interacting with APIs
- Proven background in establishing data test automation frameworks from scratch
- Practical testing experience within Databricks or an equivalent cloud lakehouse or warehouse
- Deep familiarity with Delta Lake or similar architectures
- Experience validating complex data transformations across streaming, batch, and orchestration tools such as Airflow or dbt
- Experience validating data flows through Customer Data Platforms, specifically mParticle
- Skill in triaging data anomalies and tracking pipeline failures using tools like Jira
- Experience testing REST APIs and validating data payloads between systems
- Bachelor degree in Computer Science, Data Engineering, or a related technical field
- Bring your own device policy compliance for work equipment
- Valid work visa with the right to work
Qualifications
- Familiarity with data ingestion into Braze via the Data Track API or Cloud Data Ingestion
- Experience testing customer data platform to engagement data flows, including mParticle audience syncs and event forwarding into Braze
- Experience testing privacy compliance and consent frameworks using OneTrust
- Experience embedding data quality checks into CI/CD pipelines such as GitHub Actions or GitLab CI
