How to apply for Instrumentation and Controls Engineer

About Oklo

Oklo is developing next-generation fast fission technology with the goal of providing clean, reliable, affordable energy and recycling nuclear waste. The company operates in the advanced nuclear space, which means engineers here work on reactor designs that differ from conventional light-water reactors. This is a fit for someone who wants to work on nuclear instrumentation and controls at an early-stage design company rather than an established utility.

About the role

This Instrumentation and Controls Engineer role involves developing, analyzing, and integrating measurement and control systems that support reactor operation. The position may sit in powerhouse engineering (power generation) or in the isotopes organization (isotope reactors), so the exact system focus depends on team placement. The engineer acts as a responsible engineer coordinating requirements, design, testing, and commissioning for assigned systems.

A typical day

A typical day likely involves working on requirements or design for an assigned instrumentation and control system, coordinating with other engineers on integration and analysis coupling, and reviewing feedback from design teams. The posting does not describe the daily routine in detail, so ask about team structure, meeting cadence, and how work is split between powerhouse and isotopes during the interview.

Who Oklo is looking for

• Has hands-on experience specifying and integrating instrumentation across temperature, pressure, radiation, and neutron measurement technologies.
• Understands signal conditioning, data acquisition, and logic diagrams, not just sensor selection on paper.
• Has written system and component level requirements and can trace them through design, testing, and commissioning.
• Can develop control strategies and algorithms for industrial equipment and give technical feedback to fast-iterating design teams.
• Writes clear technical reports and documents work using modern tools.

Tips for this application

• Name the specific measurement types you have worked with (temperature, pressure, radiation, neutron) in your resume bullets, since the posting calls these out explicitly.
• Describe at least one system where you owned requirements through commissioning as a responsible engineer, and state your exact role in that process.
• Include examples of control strategies or algorithms you developed for industrial equipment, with the equipment type named.
• Mention the documentation and reporting tools you use, because the posting emphasizes modern documentation tools and thoughtful technical reports.
• Address in your cover letter whether you are more interested in powerhouse engineering or the isotopes organization, since the role can reside in either.

What to cover in your cover letter

State your experience specifying and integrating instrumentation across the measurement types listed in the posting. Describe a specific system where you coordinated requirements, design, testing, and commissioning as a responsible engineer. Give an example of a control strategy or algorithm you developed for industrial equipment. Explain why you want to work on fast fission and nuclear waste recycling specifically, not just nuclear in general.

Research before applying

• Oklo's fast fission reactor design and how it differs from conventional light-water reactor instrumentation and control approaches.
• Oklo's nuclear waste recycling work and what it implies for isotope reactor systems.
• The distinction between Oklo's powerhouse engineering and isotopes organization, so you can speak to which team fits you.
• Any public regulatory or licensing information about Oklo's reactor designs, since instrumentation and controls requirements are shaped by the licensing path.

Likely interview topics

Based on the job description, expect questions about:

• How you select and specify instrumentation for a process measurement, including signal conditioning and data acquisition choices.
• A walkthrough of a system you owned from requirements through commissioning, and what went wrong along the way.
• How you develop control strategies and algorithms for industrial equipment, with a concrete example.
• Your familiarity with radiation and neutron instrumentation, and how it differs from standard process measurement.
• How you document requirements and design decisions, and how you handle feedback from fast-iterating design teams.

Common mistakes to avoid

• Listing instrumentation experience without naming the measurement types, since the posting is specific about temperature, pressure, radiation, and neutron instrumentation.
• Describing only design work and omitting testing or commissioning experience, because the role explicitly includes coordinating through commissioning.
• Treating the role as a generic controls engineering job and ignoring the nuclear reactor context, which is central to the position.
