About the company

RedoxBlox is a San Diego-based climate hardware startup building thermochemical energy storage, often framed as a “thermal battery” for high-temperature industrial heat and cleaner power production. The company’s public materials focus on engineering-heavy work: reactors, high-temperature components, and power electronics needed to run and integrate the system. Recent coverage and company updates position RedoxBlox in the commercialisation phase, hiring for productisation and scale-up rather than just lab research. Early-career visibility exists, but most publicly listed roles are written for experienced engineers.

Locations and presence

RedoxBlox is headquartered in San Diego, California, and most roles are listed as on-site in San Diego. Public hiring signals are primarily US-based with a strong engineering and operations footprint.

Palpable Score

47.4

/ 100

RedoxBlox looks like a solid place to learn if someone can get in, because the work is hands-on and close to senior engineers, and benefits are described more clearly than many startups. The main constraint for graduates is access: the company’s own job posts skew 5+ years, and public proof of junior progression is thin.

Pillar 1: Early-career access

Score

8.0

/ 20

The company has at least one public Mechanical Engineering Intern interview record, which is a real early-career entry point.

RedoxBlox mainly advertises roles asking for 5+ years (for example Mechanical Engineer and Power Electronics Engineer), which makes “0–3 years” access limited.

The company does not show a recurring internship cohort or a steady stream of junior titled roles on the main careers page, so graduate access looks occasional.

‍

Pillar 2: Hiring fairness and transparency

Score

11.0

/ 20

The company uses a clear “Apply” flow on the careers site with role pages that spell out responsibilities, working conditions, and on-site expectations.
RedoxBlox has at least one intern interview account describing a one-week process with resume walkthrough, technical questions, and time for candidate questions, which reads structured and time-bounded.
The company does not publish a standard interview map, timelines, or assessment expectations across roles (beyond individual descriptions), so transparency still depends on recruiter communication.

‍

Pillar 3: Learning and support

Score

9.7

/ 20

The company’s on-site engineering roles include lab and field exposure (high-temperature environments and collaboration with R&D and manufacturing), which can accelerate practical learning.
RedoxBlox job posts focus on ownership in ambiguous, fast-changing scope, which can be valuable experience but can also be uneven for early-career ramp without explicit coaching detail.
The company does not publish verifiable early-career support mechanics such as onboarding plans, buddying, 1:1 cadence, or review cycles in the role pages.

‍

Pillar 4: Pay fairness and stability

Score

13.0

/ 20

The company lists a strong benefits set in at least one public job post, including medical, dental, vision, 401(k), disability and life insurance, paid parental leave, and flexible vacation.
RedoxBlox states stock incentives are part of total rewards for at least one role, which is a meaningful stability signal when explained alongside benefits.
The company does not publish salary ranges in the role pages reviewed, which caps pay-fairness confidence for early-career candidates.

‍

Pillar 5: Early-career outcomes

Score

5.7

/ 20

The company does not publish early-career outcomes such as intern-to-offer conversion, promotion timelines, or 12–24 month retention metrics.
RedoxBlox has very limited independent employee-review coverage that speaks to progression and manager quality, so outcomes are hard to validate publicly.
The company’s LinkedIn footprint suggests a growing team, but public information is not enough to summarise repeatable junior-to-mid progression patterns without guessing.
