About the company

1KOMMA5° is a clean energy company combining local installation (solar, batteries, EV charging, heat pumps) with an energy software layer called Heartbeat AI and a dynamic electricity tariff called Dynamic Pulse. The company describes a “one-stop-shop” model across multiple countries, with many local sites and a large field workforce alongside a central tech and operations org. Public company materials position 1KOMMA5° as a Hamburg-founded scale-up that has grown through acquiring and integrating installation businesses, while building Heartbeat AI as a core platform.

Locations and presence

1KOMMA5° is headquartered in Hamburg and publicly lists operations across seven markets, with dozens of local locations. Hiring spans central teams (often tied to Berlin and Munich hubs plus remote options) and local craft and commercial roles across many German regions.

Palpable Score

70.3

/ 100

1KOMMA5° offers plenty of real entry points through working-student roles, internships, and “Junior” roles capped at around 0–2 years, plus role descriptions that mention mentorship and early responsibility. The biggest drag is consistency: public candidate feedback includes ghosting and long gaps after interviews, and salary ranges are rarely shown on postings, so pay fairness is harder to judge before applying.

Pillar 1: Early-career access

Score

16.0

/ 20

The company lists multiple early-career routes at the same time, including Working Student Software Engineering, Working Student Data/BI Analyst, and Internship Energy Operations, across tech, ops, and supply chain.
1KOMMA5° advertises a permanent “Junior Operations Manager Supply Chain” role asking for up to two years’ experience and explicitly counts prior Werkstudent experience toward that threshold.
The company’s employer profile text states applications are welcome from career starters and apprentices (“Azubis”), which expands access beyond university-only pathways.

Pillar 2: Hiring fairness and transparency

Score

13.0

/ 20

The company runs applications through an ATS flow (Personio) with consistent job pages and a clear data privacy statement, which reduces “email into a void” risk.
1KOMMA5° has public interview reports describing friendly conversations but long scheduling delays and then silence after the process, which is a material fairness gap for early-career candidates.
The company also has applicant feedback praising a transparent process for a Werkstudent application (including explanation of next steps), so process quality looks uneven rather than uniformly poor.

Pillar 3: Learning and support

Score

15.3

/ 20

The company writes “mentorship and support” directly into the Working Student Software Engineering role, alongside pairing with experienced engineers, product managers, and designers in a cross-functional team.
1KOMMA5° frames internships like Energy Operations around a steep learning curve with room for feedback, then moving into owning a project after onboarding with guidance from a manager.
The company repeatedly highlights early access to decision-makers and management in student roles, which can be high-value learning when paired with clear scope and regular check-ins.

Pillar 4: Pay fairness and stability

Score

13.0

/ 20

The company offers stability-style benefits that matter early career, including company equipment (MacBook and iPhone in some roles), EGYM Wellpass, and discount platforms, plus hybrid or Germany-wide remote options in several student postings.
1KOMMA5° rarely shows salary ranges on the official job ads reviewed here, which limits pay transparency for graduates comparing offers.
The company has substantial third-party salary data (including intern and working-student entries and salary satisfaction metrics), which helps benchmarking, but first-party ranges would lift confidence.

Pillar 5: Early-career outcomes

Score

13.0

/ 20

The company has a strong volume of employee feedback on kununu with high recent recommendation rates and a solid “career and training” sub-score, which is a positive progression proxy even without published promotion rates.
1KOMMA5° also has negative signals in employee reviews about overtime and work-life friction in some teams, which can undermine early-career retention even when the mission is strong.
The company’s LinkedIn job footprint and the company’s own ATS show repeat hiring for working students and interns across functions, but public sources do not provide conversion rates (intern-to-full-time) or typical time-to-promotion.
