• Comfortable operating in ambiguous environments and helping define structure,
patterns, and processes

Preferred Qualifications

• Experience with Nx monorepo tooling and shared library architecture
• Familiarity with NGXS or NgRx for Angular state management
• Experience with cloud platforms (AWS, GCP, or Azure) and cloud-native design patterns
• Experience implementing real-time systems (WebSockets, SSE) and asynchronous
processing (e.g., Celery)
• Familiarity with Docker, containerized deployments, and infrastructure-aware
development
• Experience with Redis caching strategies and message brokering patterns
• Exposure to data visualization tools such as Three.js
• Background working across multiple products or platform-based architectures

Nice to Have

• Experience in the oil and gas industry, particularly with well completions operations

• Familiarity with concepts such as stage tracking, perforation intervals, pump schedules,
and treatment design
• Exposure to upstream data standards or oilfield service company workflows
• Experience building systems for operational, safety-critical, or compliance-driven
environments

What Success Looks Like

• The team delivers consistently with clear patterns and reduced rework
• Frontend and backend systems feel cohesive, maintainable, and scalable
