• Debug, troubleshoot, and resolve complex production issues

• Assess existing systems and contribute to improvements in architecture, performance, and developer experience
• Help reduce technical debt and improve system health through incremental modernization efforts
• Implement best practices across service design, data modeling, and platform reliability

• Design and implement Postgre
  
  SQL data models optimized for transactional use cases
• Support development of Snowflake data models, schemas, and pipelines
• Apply best‑practice data modeling techniques:
  • Normalization and relational modeling
  • Dimensional models (star schema concepts where applicable)

• Build reusable services and frameworks that improve developer velocity and platform consistency
• Work with application teams to integrate and adopt platform capabilities
• Contribute to documentation, examples, and reference implementations that simplify adoption

• Provide technical guidance to engineers through code reviews and design discussions
• Mentor engineers and help elevate overall technical quality across teams
• Influence architecture through implementation and delivery, not just design artifacts

• 12+ years of professional software engineering experience

  • Containerized systems and modern Dev Ops practices
• Experience designing and operating large‑scale, production systems

• Experience building or supporting data platforms, pipelines, or analytics systems
• Familiarity with event‑driven systems and streaming architectures
• Experience with AI/ML or GenAI‑enabled systems and workflows
• Exposure to graph databases (Neo4j, Neptune) or complex relationship modeling
• Experience improving engineering productivity through automation and developer tooling

• Consistently deliver high-quality, scalable platform code
• Improve platform reliability, performance, and usability
• Enable other teams to build faster through reusable, well‑designed services
• Influence system direction through practical, effective engineering decisions

• Strong hands‑on builder mindset
• Ability to operate at depth in complex systems
• Pragmatic and solutions‑oriented
• Strong collaborator across engineering teams

• Salary range: $166,500 – $250,000 per year (based on skills, experience, and location)
• Potential performance‑based bonus
