What are the key skills and qualifications needed to thrive as a stack testing technician, and why are they important?

To thrive as a Stack Testing Technician, you need a solid understanding of environmental science, air sampling methods, and relevant EPA regulations, typically supported by a science degree or equivalent technical training. Familiarity with stack testing equipment, data logging systems, and certifications such as Source Evaluation Society (SES) accreditation are commonly required. Attention to detail, problem-solving abilities, and effective teamwork distinguish top performers in this field. These skills ensure accurate emission measurements, regulatory compliance, and reliable reporting for environmental protection.

What are some common challenges faced by professionals in stack testing, and how can they be addressed?

Professionals in stack testing often encounter challenges related to variable weather conditions, strict regulatory requirements, and the need for precise data collection. Working at elevated heights and handling sensitive equipment also require adherence to stringent safety protocols. To address these challenges, teams typically undergo thorough safety training, use specialized monitoring instruments, and maintain clear communication with other environmental and engineering staff to ensure accurate results and regulatory compliance.

What is stack testing?

Stack testing refers to the process of measuring the emissions released from industrial stacks or chimneys to ensure compliance with environmental regulations. It involves collecting and analyzing samples of gases and particulates emitted during industrial processes. The results help determine if a facility is meeting air quality standards and can identify areas for improvement. Stack testing is typically required by regulatory agencies to monitor pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter.

What is the difference between Stack Testing vs Environmental Technician?

AspectStack TestingEnvironmental Technician
CertificationsEPA Method 3, 6, 9 certificationsEPA certifications, safety training
Work EnvironmentField testing at industrial sites, power plantsField and lab work in environmental sites
Industry UsageIndustrial, power generation, manufacturingEnvironmental consulting, government agencies

Stack Testing and Environmental Technicians both work outdoors and require environmental certifications. However, Stack Testing focuses specifically on emissions testing at industrial stacks, while Environmental Technicians handle broader environmental assessments and sampling. Both roles are essential in environmental compliance but differ in scope and specific certifications.

Job description

Job Summary:
True Anomaly is a company focused on delivering decisive capabilities for space superiority. They are seeking a Staff Full Stack Software Engineer to lead the technical direction of their spacecraft modeling and ground control platform, bridging military objectives with software solutions.
Responsibilities:
• Lead and deliver large-scale, cross-functional initiatives that span the entire stack, aligning frontend experience, backend infrastructure, and system architecture with strategic company objectives, from technical vision through production deployment and long-term evolution
• Define and drive the full-stack technical roadmap and architectural strategy, establishing patterns, frameworks, and systems that enable the entire engineering organization to move faster across both React/TypeScript and Elixir codebases
• Serve as the primary technical decision-maker for cross-stack architecture, evaluating and adopting new technologies, defining the boundaries and contracts between frontend and backend systems, and establishing engineering standards that balance innovation with maintainability
• Proactively identify systemic technical debt, scalability challenges, and architectural limitations across the stack, then build business cases, secure buy-in, and lead multi-quarter initiatives to address them
• Elevate the engineering organization through technical mentorship, establishing best practices, leading design reviews, and developing the skills of senior, mid-level, and junior engineers across both frontend and backend disciplines
• Partner with executive leadership, product, design, space operations, and astrodynamics teams as a key technical stakeholder, influencing product strategy and company direction with a perspective that encompasses the entire technical surface
• Drive engineering efficiency and excellence by establishing metrics, tooling, and processes that improve code quality, system reliability, deployment velocity, and developer experience across the stack
• Build and maintain technical documentation, architectural decision records, and knowledge-sharing systems that scale organizational learning
• Represent the full-stack engineering perspective in strategic planning, resource allocation, and cross-company technical decisions Identify and develop emerging technical leaders within the team, creating growth pathways and opportunities for engineers to expand their impact across the stack
Qualifications:
Required:
• 12+ years of software development experience, with demonstrated expertise across both frontend and backend development
• Expert-level mastery of HTML/CSS and modern TypeScript/JavaScript, including deep understanding of performance optimization, browser internals, memory management, and runtime characteristics
• Deep expertise in modern React and the broader frontend ecosystem, including architectural patterns for large-scale applications, advanced state management, performance profiling and optimization, and emerging frontend technologies
• Expert-level mastery of Elixir and OTP, including deep understanding of BEAM internals, scheduling, memory management, garbage collection, process architecture, and runtime characteristics at scale
• Deep expertise in designing, building, and evolving large-scale distributed systems, including architectural patterns for fault tolerance, consistency, availability, clustering, and horizontal scalability
• Proven track record of establishing comprehensive testing strategies across the full stack, including unit, integration, property-based, and end-to-end, including championing testing culture and tooling adoption
• Extensive experience designing, building, and evolving component libraries, design systems, service architectures, and internal infrastructure that serve multiple teams and products
• Expert-level understanding of distributed systems integration patterns including gRPC, REST, WebSockets, and GraphQL, with experience defining API contracts and influencing architecture decisions across the stack
• History of leading technical initiatives in Git-based workflows, establishing code review standards, and fostering collaborative engineering culture
• U.S. Citizen and eligible for DoD Secret or TS/SCI clearance
Preferred:
• Bachelor’s degree in computer science or similar discipline
• Proven experience as a technical lead, staff engineer, or principal engineer on production systems with significant user bases and business-critical requirements, with responsibility spanning multiple layers of the stack
• Track record of leading large-scale migrations, architectural overhauls, or platform rewrites across frontend and backend systems while maintaining product velocity and system reliability
• Deep expertise building and optimizing complex, data-intensive applications with demanding performance requirements (real-time processing, large-scale datasets, complex visualizations, distributed systems) across the full stack
• Advanced proficiency with Three.js, React Three Fiber, WebGL, or other web-based 3D rendering technologies, including low-level performance optimization and shader programming
• Deep mastery of OTP including BEAM scheduling, GenServers, run queues, pg, the Actor model, dynamic supervisors, registries, distributed process groups, and custom OTP behaviours, with experience pushing the boundaries of the runtime
