Based on a real posting (view original, posted October 13, 2026, accessed November 3, 2026). Postings close. Interview for it anyway.

The role

  • Own and improve the company’s annual Scope 1, 2, and 3 greenhouse gas inventory, from collecting energy, logistics, and supplier data through validating it.
  • Run life cycle assessments (cradle-to-gate and full LCA) and support Environmental Product Declarations for building products.
  • Build dashboards and turn the numbers into recommendations for plant, product, and leadership teams.
  • Support sustainability disclosures and ratings (CDP, EcoVadis) and customer data requests.
  • Work with cross-functional teams on energy, waste, and circularity projects.

What they’re looking for

  • A degree in sustainability, environmental science, engineering, or a related field.
  • Working knowledge of the GHG Protocol and ISO 14064.
  • Hands-on LCA or product carbon footprint experience (SimaPro or GaBi is a plus).
  • Strong Excel skills, with Power BI a plus. Ability to explain technical results to non-experts.
  • The posting encourages people to apply even if they don’t meet every listed requirement.

Know the employer

Johns Manville is a Denver-headquartered building-products manufacturer (insulation, roofing, and engineered products) and a Berkshire Hathaway company. Architects and builders increasingly ask for product-level carbon data, which is a big reason this role exists.

Interview room

Candidate: stop reading here. Everything below is for the panel.

Panelists: open only your own seat. Each seat’s questions were written for this job. Ask one of them, then follow up in your character’s style.

Every round, each panelist draws a mood card. Keep it secret and play it lightly.

Tap to draw. Draw again each round.

Here, you are: JM’s senior LCA and GHG data lead. You built the current inventory spreadsheet and know every shortcut in it.

Ask one of these:

  1. “Our biggest emissions category is Scope 3 purchased goods, and supplier data is patchy. How would you build an estimate this year that we can defend, and improve it next year?”
  2. “Walk me through a cradle-to-gate LCA for one of our insulation products. Which assumptions could swing the result the most?”

Then follow up: when they use a buzzword (modeled, analyzed, managed, data-driven), ask “What specifically did you do?” or “How would you know if that was wrong?”

More about Riley

Story. A data feed your team depends on broke again last week, and you’ve been patching it ever since. You’ve been burned by hires who listed “R” and “GIS” on their résumé and then couldn’t clean a messy spreadsheet.

Quirks. Friendly but literal. You ask for numbers (“How many sites? How many years?”) and take notes.

Listen for: specific tools and steps, real QA/QC habits, and honesty about gaps.

Here, you are: Director of Sustainability. You own the CDP and EcoVadis deadlines and the reporting calendar.

Ask one of these:

  1. “Sales needs a product carbon number to win a big bid in six weeks. Our EPD process normally takes four months. What do you do?”
  2. “CDP, EcoVadis, and three customer questionnaires are all due the same month. How do you keep from drowning?”

Then follow up: politely interrupt idealistic answers with “That sounds great in a seminar. What’s the version we can deliver by Friday?” If an answer runs past about 90 seconds: “Give me the headline.”

More about Pat

Story. You chair this search committee. Your puppy chewed up a corner of the carpet overnight, so the morning started early, and you have a budget meeting right after this. You love good science that ships on time.

Quirks. You keep an eye on the clock.

Listen for: prioritization, concrete deliverables, and concise answers.

Here, you are: Lead of the plant-engagement team. You spend your days convincing plant managers that sustainability data matters.

Ask one of these:

  1. “A plant manager in another state thinks the sustainability team just creates paperwork. How do you get their energy data and their buy-in?”
  2. “Explain the difference between Scope 1, 2, and 3 emissions to me like I’m a plant-floor supervisor.”

Then follow up: “What would the other person say happened?” or “What did that teach you about how you work?” After each answer, pause for a few seconds before speaking.

More about Morgan

Story. Last week you ran a field day for a group of ninth-graders, and it reminded you how hard it is to explain this work simply. You’ve seen strong scientists struggle because they couldn’t explain their work to a non-scientist or get along with the person at the next desk.

Quirks. Warm, and comfortable with silence.

Listen for: a real story (STAR), empathy, self-awareness, and plain language.

Here, you are: Procurement manager at one of JM’s raw-material suppliers. You’ve just been asked for product-level emissions data.

Ask one of these:

  1. “You want our product-level emissions data. That’s competitive information. What’s in it for us?”
  2. “We’re a small supplier. Who’s going to pay for us to measure this?”

Then follow up: say “Huh?” every time they use an acronym or jargon without explaining it.

More about Dale

Story. You’re not on staff. You drove a couple of hours to sit in on this panel because this hire will be working with you.

Quirks. Plainspoken and skeptical, but not hostile. If they actually listen, you warm up.

Listen for: plain language, respect, and whether they ask you questions.

Pods of 3 only. You’re both Riley and Pat. Ask one Seat A question and one Seat B question from this job, and use both follow-ups: “What specifically did you do?” and “What’s the version we can deliver by Friday?”
