ABOUT THE CLIENT

Our client is a global nonprofit technology organization dedicated to helping people discover, preserve, and connect family history data. They operate large-scale, cloud-based platforms used by millions worldwide, where data accuracy, integrity, and reliability are critical to the mission.

ABOUT THE ROLE

We are seeking a Senior Software Engineer (Java) who combines strong backend engineering skills with a deep interest in data quality and large-scale data correction. This is a highly technical position focused on investigating data issues, debugging complex systems, and writing substantial Java code to repair and improve massive datasets.

You’ll work in an iterative, fast-moving environment, diagnosing issues across distributed systems, building safe and repeatable repair workflows, and ensuring data correctness across millions of records.

- Leverage AWS services (such as S3, SQS, and Lambda) to support queue-driven and batch workflows.

- Analyze system behavior related to performance, concurrency, and memory usage.

- Clearly communicate findings, risks, and recommendations to technical and non-technical stakeholders.

- Hands-on experience with AWS, including services such as S3, SQS, and Lambda.

- Solid understanding of performance optimization, concurrency, and memory-efficient design patterns.

- Ability to design reliable, repeatable data repair workflows.

- Comfort operating in ambiguous, evolving problem spaces and deriving practical solutions.

- Strong communication skills, with the ability to summarize complex technical findings clearly.

NICE TO HAVE

- Experience working with genealogical, historical, or highly interrelated datasets.

- Familiarity with queue-driven architectures and event-based processing.

- Experience improving data integrity in legacy or long-lived systems.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
