[Hiring] Staff Software Development Engineer in Testing @Murmuration

Role Description

Do you see yourself as an engineer with deep roots in software and data engineering who is passionate about data quality - and ready to build the systems that prove it?

As a Staff Software Development Engineer in Testing (SDET), you will embed in our Data Platform team as its senior-most testing authority, responsible for developing a deep understanding of our entire data platform and then designing and driving the implementation of the Organizer product’s automated integration testing strategy. This role is built for someone who is first and foremost a strong engineer - with substantial experience in software development and/or data engineering - and who brings a genuine passion for data quality and testing as a craft.

This is a great opportunity to build something with significant impact from the ground up. You will be expected to quickly achieve mastery of our streaming data pipelines and distributed systems architecture, and then have the creative latitude to design and implement a comprehensive end-to-end test framework - with real organizational investment and impact behind it. You will influence testing strategy organization-wide, set technical standards, and serve as a force multiplier for the engineers around you.

What You’ll Do

• Rapidly develop a comprehensive understanding of our entire data platform (its architecture, data flows, business logic, and system interdependencies) to serve as the foundation for a testing strategy;
• Work with our application QA Engineering Team to understand our existing testing strategy and tools; this will help you identify how you can fill the gaps in data testing;
• Design, architect, and lead the implementation of an integration testing framework for the Organizer application's streaming data platform, ensuring it is complementary to existing infrastructure;
• Design automated validations that query and compare data across multiple storage systems (e.g., MongoDB, DynamoDB, Pinot) to ensure end-to-end data correctness;
• Embed automated tests within CI/CD pipelines to establish regression baselines and continuously validate new feature development;
• Design tests that rigorously account for eventual consistency, asynchronous processing, and time-based behaviors inherent to distributed systems;
• Define and own the long-term quality and testing strategy for the data platform, aligning it with organizational reliability, observability, and engineering excellence goals;
• Evaluate, select, and integrate tools, frameworks, and technologies to advance automation and data validation capabilities across the organization;
• Implement automated performance and throughput benchmarks for critical pipeline components and own the standards by which results are evaluated;
• Participate in engineering design reviews with a quality-first lens, ensuring testability, observability, and data correctness are built into systems from the start;
• Proactively identify, investigate, and drive resolution of data quality issues and systemic reliability risks; collaborate with data engineers to implement fixes and preventative measures;
• Lead post-incident reviews for data quality events: authoring clear timelines, facilitating root cause analysis, and driving follow-through on remediation action items;
• Mentor engineers across the data platform and QA teams, establishing testing best practices and elevating the team's overall quality culture;
• Represent the data platform's quality posture in cross-functional technical discussions and influence engineering standards across teams.

Qualifications

• 12+ years of experience in software engineering, data engineering, or SDET roles, with a track record that demonstrates strong software development fundamentals;
• Deep proficiency in Python (or equivalent programming language) and experience writing production-quality, maintainable code;
• Demonstrated experience designing and architecting complex test frameworks or automation systems with strong, well-reasoned opinions about how to do it well;
• Deep experience with streaming data pipelines, event-driven architectures, or distributed data systems (e.g., Kafka, Spark, Flink, or equivalent);
• Strong command of NoSQL databases (e.g., MongoDB, DynamoDB) and relational databases;
• Experience testing or building systems in cloud-native, serverless environments (e.g., EventBridge, Lambda, asynchronous workflows);
• Experience testing GraphQL or REST APIs;
• A genuine passion for testing as a discipline: someone who sees quality engineering as a craft, not a checkbox;
• Demonstrated ability to operate with a high degree of autonomy: to scope ambiguous problems, build a plan, and drive to outcomes independently;
• Proven experience influencing testing or quality strategy across teams or an engineering organization;
• Excellent debugging and analytical skills in complex, distributed, data-intensive environments;
• Strong written and verbal communication skills, with the ability to document architecture decisions and present technical approaches to both engineering and non-technical stakeholders.

Nice to Haves

• Experience with Scala and/or JavaScript;
• Experience with performance benchmarking, load testing, or throughput analysis;
• Experience with OLAP data stores (e.g., Pinot, Snowflake);
• Familiarity with AWS (e.g., S3, Lambda, ECS, Lambda) and data orchestration tools (e.g., Airflow, Kafka, Spark);
• Experience with monitoring/alerting tooling (e.g., Datadog);
• Familiarity with Playwright.
