Position Overview

Software Engineer II joining our US engineering team to help design and build large-scale data pipelines and the platforms and services built on top of them. You'll own features end-to-end—from design through production support—on systems that process hundreds of millions to billions of records against fixed delivery schedules. The work spans new services and long-lived systems, combining cloud-native infrastructure with third-party and on-premises integrations.

Key Responsibilities

• Design, develop, test, and deploy features across our data pipelines and platform services, owning them through to production.
• Implement distributed data processing jobs, along with the orchestration and configuration that drive them.
• Build services and APIs that expose pipeline data and platform capabilities to internal teams and clients.
• Integrate external systems—including data vendors, client delivery endpoints, cloud warehouses, and third-party software—and make those integrations observable and recoverable when they fail.
• Add instrumentation, alerting, and automated tests so problems surface before reaching a client.
• Contribute to infrastructure-as-code and CI/CD pipelines.
• Participate in code reviews, incident response, and knowledge sharing across the team.

• Bachelor’s or Master’s degree in Computer Science, Engineering, or equivalent practical experience.
• 2–4 years of professional software engineering experience building and supporting production software.
• Strong programming ability in at least one modern language, with the judgment and adaptability to pick up others.
• Solid SQL skills, with experience across relational databases and/or cloud data warehouses.
• Experience with distributed data processing at scale (e.g., Spark) or comparable large-scale data systems.
• Hands-on experience with a major cloud platform (ideally AWS)—specifically object storage, IAM, and at least one compute service.
• Sound production habits: automated testing, version control, code review, and debugging from logs and metrics rather than guesswork.
• Bonus: Experience with EMR, infrastructure-as-code (such as Terraform), CI/CD tooling, or handling PII under contractual or regulatory constraints.

Location: Kirkland, WA (In-Office 5 Days Per Week with remote flexibility)

Benefits & Compensation

• Compensation: $120,000–$145,000 annual base salary, commensurate with experience and qualifications, plus a 10% target annual bonus.
• Flexible Time Off (FTO) and Company Holidays
• Medical, Dental, Vision, and HSA Benefits
• Voluntary Life & AD&D Insurance
• Short-Term & Long-Term Disability Coverage
• Critical Illness & Accident Insurance
