What our energytech startup customers are saying

Having a developer who can get started on work at the drop of a hat and a CTO who can oversee and QA all work is an unbeatable deal.

Trading platform web app rebuild
The Challenge:
BananaGun had a broken legacy codebase from a previous agency. After two years of missed deadlines and unstable releases, they needed someone who could take over and deliver fast.
Solution:
We assembled a small team of senior React developers to rebuild the entire platform from scratch. The new codebase was clean, stable, and built for scale — allowing their internal team to move faster again.
The Results:
MVP launched in 6 months, outperforming prior providers who couldn’t deliver in 2 years.

Web development for the dashboards of IoT integrations (subsequently sold to E.ON)
The Challenge:
After raising $40M, gridX needed senior React engineers fast. Their hiring pipeline couldn’t keep up with demand.
Solution:
We integrated two of our senior developers directly into their team within 48 hours.
The Results:
After a 24-months of collaboration GridX was acquired by the German energy giant E.ON. The development was continued internally based on the solid foundation built by our team.

The Challenge:
Mechaniker needed a team that could build and think — not just code. Since their founder lacked a technical cofounder, we stepped in to own the product.
Solution:
We took on both full-stack development and CTO-level direction, building the platform from scratch.
The Results:
Launched the full product in 6 months — from concept to launch.

How to Hire a React Developer for your energytech startup

What type of React developer do I really need for my energytech product?

Match to your company stage and team size. Early-stage energytech needs fast shippers who can handle messy, real-time energy data and work without full specs.

Later-stage companies can prioritize accuracy and stakeholder management over speed.Small teams need strong solo builders; larger teams need people who can coordinate with hardware, data, and product stakeholders.

How do I decide between a generalist and a specialist?

Early-stage energytech companies need a reliable fullstack developer who can:
- Build the frontend UI in ReactWrite backend APIs for energy data ingestion
- Handle basic deployment and DevOps tasks

Later, as you grow and the product scales, you’ll split into specialists: a frontend dev who focuses on real-time visualizations, a backend dev for high-volume data ingestion, and a data engineer for analytics pipelines.

What’s the right mix of technical skill vs. product sense for this stage?

Early stage: entrepreneurial devs who work from rough ideas, make product calls as they code, and adapt quickly.

Later stage: team-oriented devs who execute within structured processes and collaborate across multiple squads.

How do I compete for talent without paying top-of-market salaries?

You can’t match big-company cash, and large equity giveaways hurt future fundraising. But you can leverage your mission (climate impact), ownership, and growth opportunities.

ReactSquad can connect you with vetted React talent in data-heavy domains for ~50% less than US freelancers.

How fast should my hiring process be?

Target 2–3 weeks from first touch to offer.
Energy/data-savvy React devs are rare. A slow process means losing them to other climate or SaaS companies.

ReactSquad offers fast matching of quality energytech developers within 48 hours, saving you time and money.

What’s my plan if my first hire doesn’t work out?

Have a 3-month probation with clear metrics: shipping production features, handling energy data, collaborating with non-software teams. If they fall short, part ways quickly — a bad fit can stall your roadmap more than an unfilled role.

What is React?

React.js is a JavaScript library for building dynamic user interfaces. It lets developers create reusable components, making apps faster to build, easier to maintain, and more responsive—without needing to reload the whole page each time something changes.

Technical Proficiency and Soft Skills

  • Strong understanding of core JavaScript and React fundamentals (JSX, components, state, props, lifecycle methods)
  • Experience with key tools in the React ecosystem (Redux, React Router, UI libraries)
  • Ability to build reusable, modular, and maintainable components
  • Proficiency in working with APIs and handling async data
  • Clean coding practices and version control with Git
  • Problem-solving and critical thinking in debugging and development
  • Effective communication and teamwork in cross-functional environments

Finding React Developers

You can find dedicated React engineers on vetted talent platforms which focus on experienced developers. Clutch and GoodFirms list React development agencies with client reviews. GitHub, Stack Overflow, and LinkedIn can also help identify active React teams. Consider hiring remotely to expand your access to skilled global teams.

OR save yourself the time and hire directly from us. You can get expert part-time devs within hours.

The Cost of Hiring React Developers

React developers typically charge $70 to $160 per hour, depending on experience and location. In the US, average React developer salaries range around $120,000 annually, with variations across different states. Junior developers may start around $50/hour, while senior talent in the U.S. or Western Europe can command $100/hour or more.

ReactSquad offers startup-friendly rates at $85 per hour.
