What does a senior instrument engineer do?

A Senior Instrument Engineer is responsible for designing, specifying, installing, and maintaining instrumentation and control systems used in industrial processes. They ensure that these systems function efficiently, safely, and reliably to monitor and control variables such as pressure, temperature, and flow. Senior Instrument Engineers often lead projects, troubleshoot complex issues, and provide technical guidance to junior engineers. They also collaborate with other engineering disciplines to optimize process performance and comply with industry standards.

What are the key skills and qualifications needed to thrive as a senior instrument engineer, and why are they important?

To thrive as a Senior Instrument Engineer, you typically need a degree in engineering (often electrical, instrumentation, or control engineering) and extensive experience with instrumentation design, installation, and maintenance. Proficiency with industry-standard tools such as PLCs, DCS, CAD software, and familiarity with relevant codes and certifications like ISA or IEC are essential. Strong problem-solving, project management, and communication skills help coordinate teams and interface with other engineering disciplines. These skills and qualities ensure the safe, efficient, and reliable operation of complex industrial processes.

What are some common challenges faced by senior instrument engineers when working on multidisciplinary projects?

Senior Instrument Engineers often encounter challenges coordinating with other engineering disciplines, such as process, electrical, and mechanical teams, to ensure instrumentation specifications align with overall project requirements. Integrating new instrumentation technologies into existing systems while maintaining compliance with safety and industry standards can also be demanding. Effective communication, strong project management skills, and adaptability are essential to successfully navigate these complexities and ensure project deliverables are met on time and within budget.

What is the difference between Senior Instrument Engineer vs Instrument Technician?

AspectSenior Instrument EngineerInstrument Technician
CredentialsBachelor's degree in Engineering, certifications like CSE or ISATechnical diploma or associate degree, specialized training
Work EnvironmentDesign, project management, troubleshooting in industrial plantsInstallation, maintenance, calibration on-site
Industry UsageEngineering firms, oil & gas, manufacturingRefineries, power plants, process industries

While both roles involve instrumentation, the Senior Instrument Engineer focuses on design, planning, and troubleshooting at a higher level, often overseeing projects. The Instrument Technician handles hands-on installation, maintenance, and calibration tasks. Both roles are essential in industrial settings but differ in responsibilities and required qualifications.

Senior Software Engineer - LIMS Modernization

LE002 Onterris Payroll, LLC

Little Rock, AR • On-site

$200 - $210/hr

Other

Posted 16 days ago

Job description

At Onterris, we build careers grounded in purpose, responsibility and real‑world impact. This role is focused on modernizing our proprietary Laboratory Information Management System (CTLIMS), a strategic asset that supports production operations across multiple labs and links to Workday in real time.

Compensation

$200,000–$210,000USD, commensurate with experience, skills, and geographic location.

Responsibilities
  • Build through Spec‑Driven Development (SDD); author Markdown specifications and architecture‑as‑code with Mermaid.js, commit to Git.
  • Establish spec‑first development templates and review habits.
  • Deliver test‑first development (TDD); build automated test coverage to enable fast, confident releases.
  • Maintain coverage standards, especially for AI‑generated code.
  • Implement architectural guardrails to keep modular boundaries and prevent monolith erosion.
  • Use AI tools (Cursor, ClaudeCode) for codebase archaeology, documentation and prototyping; contribute to .cursorrules and prompt libraries.
  • Reverse‑engineer and document legacy system modules: purpose, inputs, outputs, dependencies, data models, and technical debt.
  • Create data‑flow diagrams for sample lifecycles, Workday integration, billing triggers, instrument interfaces, and authentication/authorization.
  • Contribute to integration inventory and technical‑debt register, triaging components as Fix Now, Doc, Defer, or Accept Risk.
  • Shape CTLIMS placement within our Azure landing zone and environment tiers (production, non‑production, sandbox); support high‑availability and hybrid on‑prem design.
  • Work with Staff Engineer, cloud landing‑zone owner, and platform architects to align modernization with existing Onterris platforms.
  • Develop reference implementations and prototypes to de‑risk architecture choices.
  • Help the team move from “ready to start” to shipping without a standing start, assuming modernization is approved.
Qualifications
  • 7+ years of professional software engineering experience.
  • Strong cloud‑native engineering fundamentals (Azure preferred; AWS or GCP acceptable).
  • Demonstrated practice with Spec‑Driven and Test‑Driven Development, clean architecture, and domain‑driven design.
  • Hands‑on experience with AI‑assisted development tools (Cursor, ClaudeCode, GitHubCopilot, or similar).
  • Ability to read, reverse‑engineer, and reason about an unfamiliar or legacy codebase.
  • Comfortable producing documentation and diagrams as code (Markdown, Mermaid.js) versioned in Git.
  • Strong communication skills; can explain the “why” to experienced engineers and partner effectively across teams.
  • Respectfully challenge peers and welcome challenges from others.
  • Flexible, resilient, and curious; iterate beyond prior art.
  • Preferred: Experience reverse‑engineering or maintaining systems written in Perl or another long‑lived legacy language.
  • Preferred: Background in LIMS, scientific or regulated software (EPA reporting, chain‑of‑custody, lab accreditation).
  • Preferred: Experience with Oracle, and evaluating database migrations (e.g., toward PostgreSQL or Snowflake).
  • Preferred: Familiarity with containerization (Podman or Docker) and hybrid on‑prem/cloud deployment patterns.
  • Preferred: Exposure to enterprise integrations such as Workday.
  • Preferred: Familiarity with prompt engineering and AI workflow optimization.
