About the company

Neustark is a Swiss carbon removal company that permanently stores CO₂ by mineralising it in recycled mineral waste such as demolished concrete. The company captures CO₂ (often from biogas plants), transports it to recycling sites, and injects it into concrete granules during the recycling process so the CO₂ becomes locked in as limestone. Neustark describes active scale-up across Europe, with technical and operations work spanning logistics, measurement and verification, and industrial data systems. The company was founded in 2019.

Locations and presence

Neustark lists headquarters in Bern with hubs or offices in Zurich and Cologne, and hiring also points to a growing footprint in Poland (including fully remote roles). Roles on the careers site reference working across multiple European sites with quarterly in-person gatherings for the wider team.

Palpable Score

63.4

/ 100

Neustark is strongest on practical pay transparency and role clarity, including published salary ranges and concrete “what you’ll do” sections even for internships. The score is held back by limited entry-level volume at any one time and thin public evidence on junior promotion and long-term early-career retention.

Pillar 1: Early-career access

Score

9.8

/ 20

The company is currently advertising two paid internships (CO2 Logistic Intern and Internship Data Science AI) with real operational and data responsibilities.
Neustark’s live non-intern openings mainly start above true graduate level, including a Software Developer role asking for 3+ years’ experience.
The company shows limited breadth of 0–3 year roles across functions at the same time, so entry-level access looks occasional rather than recurring.

Pillar 2: Hiring fairness and transparency

Score

14.1

/ 20

The company publishes unusually concrete job posts that include mission scope, responsibilities, work model (hybrid or fully remote), a named recruiter contact, and salary ranges.
Neustark has public candidate reports describing a three-round interview flow and a role-relevant market case with a few days to complete.
The company does not publicly commit to a consistent timeline or assessment design across all roles, so predictability still depends on the individual hiring loop.

Pillar 3: Learning and support

Score

13.2

/ 20

The company builds hands-on learning into internship scopes, like structuring R&D and process data, working with Azure services, and building dashboards used by teams across R&D and operations.
Neustark advertises formal development support via a training-days budget (2–3 days depending on role) plus colleague-led learning lunches and regular cross-hub collaboration.
The company does not publish a junior-specific onboarding plan, mentoring setup, or review cadence, which limits visibility into how supported a new graduate would feel after week four.

Pillar 4: Pay fairness and stability

Score

15.6

/ 20

The company posts monthly salary figures for internships (CHF 2,500) rather than leaving interns to guess pay after interview.
Neustark publishes salary ranges for non-intern roles like Carbon Project Developer (€2,200–€4,200 monthly, plus a Poland range) and Software Developer (PLN 18,000–21,000 monthly).
The company lists practical benefits like public transport and mobile phone allowances, holiday allowance, and a hybrid work culture, but benefits detail still varies by country and role.

Pillar 5: Early-career outcomes

Score

10.7

/ 20

The company has mixed employee-review signals, including praise for purpose and team closeness alongside critiques about communication gaps and the realities of a fast-changing environment.
Neustark has at least one intern-specific review describing strong feedback culture and openness to new ideas, but it also mentions overtime, so sustainability depends on team and workload.
The company does not publish retention, time-to-promotion, or early-career progression data, which caps outcomes scoring beyond scattered public sentiment.
