About the company

Newcleo is a nuclear energy company working on Generation IV lead-cooled fast reactors and a MOX fuel manufacturing approach, positioned around closing the nuclear fuel cycle. The company operates across reactor design, licensing, safety, fuel, and industrial delivery workstreams, with hiring that spans engineering, science, project delivery, and corporate functions. Public-facing materials describe a workforce above 900 people across multiple European countries.

Locations and presence

Newcleo operates across France, the UK, Italy, Switzerland, and Slovakia, with roles posted for sites such as Lyon, Avignon, and areas around Aix-en-Provence. Public reporting and the company’s own materials place total workforce in the 900+ to 1,200+ range across Europe, which supports the higher headcount band.

Palpable Score

67.0

/ 100

Newcleo offers concrete early-career entry via a multi-stream UK graduate scheme and internship-style roles tied to real engineering deliverables. The main limit for the score is pay transparency across listings and the lack of public, consistent evidence on junior retention and promotion outcomes.

Pillar 1: Early-career access

Score

14.0

/ 20

The company runs a UK graduate scheme spanning Science and Engineering, Finance, IT, Commercial and Project Management, and Scientific Communications, framed as an 18–24 month programme with cross-country placements.
Newcleo posts internship roles (“Stage”) in France for engineering students, including mechanical design for MOX factory equipment and FOH and ergonomics work linked to plant design.
The company’s UK scheme page states that applications open and close on a yearly cycle, but the live careers feed can show periods with few explicitly junior vacancies, which makes access feel seasonal.

Pillar 2: Hiring fairness and transparency

Score

13.0

/ 20

The company routes applications through a dedicated careers portal with role-by-role descriptions and a consistent application entry point, which reduces “mystery process” risk for first-time applicants.
Newcleo has candidate-reported interview outcomes that skew positive overall, which supports a baseline of reasonable process experience even though detailed stage-by-stage expectations are not always public in listings.
The company does not consistently publish interview timelines, assessment formats, or feedback commitments on the careers pages, so transparency relies heavily on the individual recruiter and team.

Pillar 3: Learning and support

Score

16.3

/ 20

The company structures the UK graduate scheme around placements across projects and countries, with explicit focus on development over 18–24 months rather than a single static role.
Newcleo states that graduates are mentored and supported while working toward professional institute registration, which is a practical support signal for engineers early in chartership-style pathways.
The company’s internship role descriptions include named supervision and reporting lines (“tuteur” and unit lead), plus cross-discipline design reviews, which is the kind of scaffolding juniors need to learn safely in a regulated environment.

Pillar 4: Pay fairness and stability

Score

11.7

/ 20

The company’s graduate roles have been advertised publicly with a stated salary figure (for example, £30,000 on a 2024 graduate listing), which helps early-career applicants benchmark offers.
Newcleo does not show salary ranges on many live careers-portal postings (including internship listings), which limits pay fairness assessment for candidates who are comparing multiple employers.
The company has some benefits data visible on third-party employer profiles, but public detail is not consistent enough to confirm market competitiveness across locations and levels.

Pillar 5: Early-career outcomes

Score

12.0

/ 20

The company publishes graduate testimonials describing early responsibility and support toward professional registration, which is a positive signal for skill growth outcomes in the first 1–3 years.
Newcleo has mixed but usable employee sentiment publicly, with moderate recommendation levels, which suggests outcomes vary by team and location rather than a single consistent experience.
The company’s LinkedIn presence supports the idea of an expanding multi-country workforce, but public evidence on junior promotion rates, graduate conversion rates, or 12–24 month retention is not available and caps confidence on outcomes.
