About the company

PhysicsX is a physical AI company building AI-driven simulation software for engineering and manufacturing. The company focuses on using “Large Physics Models” and real-time, multiphysics workflows to speed up design, manufacturing, and operations decisions. PhysicsX works across sectors like aerospace and defense, automotive, semiconductors, materials, and energy. The company publicly positions Delivery as a customer-embedded team that turns models into measurable outcomes.

Locations and presence

PhysicsX is headquartered in London with a second office in New York. The company also recruits for Delivery roles in Singapore, suggesting an expanding on-the-ground customer presence in Asia.

Palpable Score

55.5

/ 100

PhysicsX has credible signs of early-career access through internships and at least one explicitly junior engineering listing, plus strong baseline benefits. The main constraint is consistency: most current open roles are mid-to-senior, and candidate feedback points to uneven interview communication, which drags down fairness and early-career outcomes.

Pillar 1: Early-career access

Score

9.0

/ 20

The company has offered internships (for example, computational chemistry and CFD-focused intern roles) aimed at Master’s and PhD-level candidates rather than broad entry-level hiring.
PhysicsX has had at least one “Junior Software Engineer” role scoped to 0–1 years of experience, which is a strong signal when it appears, but this kind of listing is not prominent in the current core job board.
The company’s main live openings skew toward “Senior,” “Lead,” “Principal,” and 3–5+ years requirements, which limits day-one access for typical grads.

Pillar 2: Hiring fairness and transparency

Score

11.0

/ 20

The company publishes a clear multi-stage interview flow (intro, problem-solving rounds, final interview) and sets expectations like hybrid working and relocation support.
PhysicsX job descriptions are detailed on scope, customer-facing travel expectations, and day-to-day responsibilities, which helps applicants self-select realistically.
The company also attracts public interview complaints about unclear formats, slow feedback loops, and generic rejection messaging, which suggests inconsistency in candidate experience.

Pillar 3: Learning and support

Score

12.5

/ 20

The company advertises “personal development” support and learning access as part of the standard package across technical roles.
PhysicsX internship descriptions include hands-on training elements and explicit mentorship language (for example, mentoring from senior engineers and feedback on technical approaches).
The company’s Delivery narratives emphasise tight collaboration across Delivery, Product, and Research, but most full-time roles still assume you can “hit the ground running,” so structured early-career ramp signals are uneven.

Pillar 4: Pay fairness and stability

Score

13.5

/ 20

The company lists a strong benefits baseline in multiple roles: equity options, private healthcare, enhanced parental leave, flexible working, and a 10% employer pension contribution (UK context).
PhysicsX has some pay transparency via posted US base-pay ranges on certain roles, plus third-party salary snapshots for technical titles, which is better than many deep-tech startups.
The company often asks candidates to state salary expectations and does not consistently publish ranges across regions and seniorities, which caps confidence for early-career pay fairness.

Pillar 5: Early-career outcomes

Score

9.5

/ 20

The company has a small but meaningful pool of public employee sentiment pointing to strong “career opportunities” ratings and fast growth learning, which is a positive outcome proxy.
PhysicsX shows headcount growth and a widening mix of technical titles on LinkedIn, but public evidence of junior-to-mid promotion arcs is limited.
The company does not publish early-career retention, promotion rates, or conversion outcomes from internships, so outcomes for new grads are hard to verify beyond anecdotal reviews.
