Overview
Climate tech encompasses technology companies addressing climate change: clean energy generation and storage, electric vehicles and charging infrastructure, carbon capture and accounting, sustainable agriculture, building efficiency, climate data analytics, and more.
The sector has grown dramatically with increased venture funding, government incentives, and urgency around climate action. Climate tech attracted over $70B in venture capital in recent years.
For hiring, climate tech combines technical engineering requirements with mission alignment. Unlike other mission-driven sectors (nonprofits, education), climate tech increasingly offers competitive compensation. The talent pool is growing as more engineers specifically seek climate-focused work.
The key insight: mission is your differentiator, not a handicap. Many excellent engineers will accept slightly lower compensation to work on climate—but increasingly, you don't have to ask them to.
Why Climate Tech Hiring is Different
Mission as Competitive Advantage
Climate tech hiring differs from general tech hiring in one fundamental way: mission is a genuine differentiator. In most industries, company mission is marketing language. In climate tech, engineers actively seek opportunities to work on climate—they're choosing the sector, not just the company.
This changes the hiring dynamic:
| Factor | General Tech Hiring | Climate Tech Hiring |
|---|---|---|
| Primary motivation | Compensation, growth, technical challenges | Mission + compensation + challenges |
| Candidate pool | Anyone qualified | Mission-aligned qualified candidates |
| Competition | Other tech companies | Climate tech + impact-adjacent sectors |
| Pitch focus | Role, growth, comp | Impact + role + comp |
| Attrition risk | Better offers | Mission misalignment, greenwashing perception |
This doesn't mean you can underpay engineers "for the mission." It means candidates who join for mission tend to be more engaged, stay longer, and work with more purpose—if the mission is real.
The Greenwashing Warning
Engineers attracted to climate tech are often deeply informed about climate issues. They can spot greenwashing quickly:
- Vague "sustainability" language without specific metrics
- Carbon credits without emissions reduction
- "Climate adjacent" positioning that's really just traditional tech
- Impact claims that don't withstand scrutiny
Be specific about your actual climate impact. Engineers will ask detailed questions. If your impact story doesn't hold up, they'll know—and they'll tell other candidates.

What Engineers Actually Need (And Don't)
Required: Technical Skills + Mission Alignment
Engineers joining climate tech need:
Strong Engineering Fundamentals
- Clean code, testing practices, system design
- The foundation is the same as any software role
- Climate tech isn't building simpler software—it's building impactful software
Learning Ability
- Climate domains involve new concepts (carbon accounting, grid dynamics, battery chemistry)
- Engineers learn this on the job
- What matters is curiosity and learning speed
Mission Alignment
- Genuine interest in climate outcomes
- Not just "I like the sector"—understanding of why climate matters
- This doesn't mean being an activist—it means caring about impact
Comfort with Ambiguity
- Many climate tech companies are defining new markets
- Regulations are evolving, business models are experimental
- Engineers who need perfect clarity may struggle
Not Required: Climate Science Degrees
This is the biggest misconception in climate tech hiring. Engineers don't need:
- Environmental science degrees
- Climate policy expertise
- Prior climate tech experience
- Energy industry background
Domain knowledge is learned on the job. A backend engineer building carbon accounting software doesn't need to understand atmospheric chemistry—they need to understand APIs, data pipelines, and how to translate business requirements into code.
Where Domain Knowledge Helps
Certain specialized roles benefit from domain background:
| Role | Domain Knowledge Value |
|---|---|
| Data Scientist (climate risk) | High—climate modeling expertise accelerates impact |
| Hardware Engineer (energy) | Moderate—electrical engineering fundamentals matter |
| Software Engineer (general) | Low—technical skills transfer directly |
| ML Engineer (climate models) | Moderate to High—depends on application |
For most software roles, domain expertise is a nice-to-have that reduces ramp time, not a requirement.
The Transfer From Other Industries
Engineers from these backgrounds adapt quickly to climate tech:
- Fintech/Payments → Carbon markets, energy trading
- IoT/Hardware → Energy systems, EV charging, smart buildings
- Enterprise SaaS → Carbon accounting, climate analytics platforms
- Logistics/Supply Chain → Sustainable logistics, supply chain carbon
- Data Engineering → Climate data, emissions tracking
Compensation Reality: Increasingly Competitive
The Old Story vs. Today
Old narrative: "Climate tech pays less—you're trading salary for mission."
Current reality: Well-funded climate tech companies increasingly match or approach mainstream tech compensation.
| Level | General Tech | Climate Tech | Gap |
|---|---|---|---|
| Mid (3-5 YOE) | $140-175K | $130-165K | 5-10% |
| Senior (5-8 YOE) | $175-225K | $165-215K | 5-10% |
| Staff (8+ YOE) | $220-280K | $200-260K | 10-15% |
Ranges vary significantly by location, company funding stage, and domain.
Why the Gap is Closing
Increased Funding
Climate tech venture funding has grown dramatically. Well-funded companies can pay competitively.
Competition for Talent
Climate tech companies compete with FAANG, fintech, and well-funded startups. Market dynamics push compensation up.
Mission as Leverage
Some candidates accept 5-10% less for meaningful climate work. This isn't exploitation—it's engineers choosing their tradeoffs.
Government Incentives
IRA (Inflation Reduction Act) and similar policies have injected capital into climate tech, improving compensation ability.
Equity Considerations
Climate tech equity can be particularly attractive:
- Clear paths to value: Many climate companies have real revenue models (energy sales, SaaS subscriptions)
- Regulatory tailwinds: Government policy is pushing toward climate solutions
- Growing markets: Climate tech markets are expanding, not contracting
- Mission alignment: Employees often hold equity longer due to mission commitment
For candidates, climate tech equity isn't speculative "what if" value—many companies have tangible business models and regulatory support.

Building Climate Tech Engineering Culture
Onboarding That Teaches Domain
Most engineers need climate domain onboarding. Invest in teaching:
- Your specific climate domain
- How your product creates impact
- Industry context and players
- The metrics that matter
Make Impact Visible
Create dashboards, all-hands metrics, and regular updates on climate impact. Engineers are motivated by seeing their work matter.
Enable Contribution Beyond Code
Some engineers want to contribute to climate beyond their job—volunteering, policy advocacy, open source. Enable this when possible.
Avoid Greenwashing Fatigue
Be honest about your impact and limitations. Engineers will trust you more for acknowledging where you fall short than for over-claiming.
