At Ostrom, you'll work in a dynamic, open environment where you can be yourself, take on challenges, and grow both personally and professionally.
Environmental Impact: Each customer who switches to Ostrom on average helps offset 1.5 tons of CO2 emissions per year compared to the average German energy mix.
VSOP: On top of offering a competitive salary you will have access to company shares to ensure you can truly be part of the journey.
Relocation package: We won't let distance get in the way, we offer visa and relocation support.
Trust-based Team: A truly flat hierarchy and transparent company culture, where everyone's voice matters.
Benefits: An annual learning budget, company-pension scheme, company events, discounted gym membership, public transport ticket, e-bike or e-moped, Futurebens or monthly vouchers - the choice is yours.
Stay In The Loop: We believe in transparent communication — from weekly town halls and quarterly updates to regular retrospectives. Got feedback or an idea? We're all ears.
Work Together, Celebrate Together: We thrive on collaboration. Wins are shared and so are the celebrations from monthly happy hours to team trips and company events.
Work Your Way: Whether you prefer the office, your home desk, or a sunny spot in Sardinia — you work where you work best.
Learn By Doing: We grow together with personal development paths, learning budgets, and regular knowledge-sharing sessions. Try things out, learn along the way, and keep moving forward.

Wertschätzung, die sich auszahlt: Neben einem attraktiven Gehalt erhältst du bei uns VSOPs – Unternehmensanteile, mit denen du direkt am Erfolg von Ostrom beteiligt bist.
Relocation package: Entfernung ist für uns kein Hindernis. Wir unterstützen dich mit einem umfassenden Relocation- und Visapaket beim Umzug nach Deutschland.

Benefits: Du erhältst ein flexibles Paket mit vielen Extras – von einem jährlichen Weiterbildungsbudget, über eine betriebliche Altersvorsorge, bis hin zu vergünstigten Fitnessstudio-Mitgliedschaften, einem Jobticket oder deinem eigenen E-Bike bzw. E-Roller. Alternativ wählst du monatliche Gutscheine oder FutureBens – du entscheidest, was dir wichtig ist.
Transparenz: Ob in wöchentlichen Townhalls, vierteljährlichen Updates oder offenen Retrospektiven – wir glauben an klare Kommunikation und kontinuierlichen Austausch.
Erfolge feiern wir gemeinsam: Teamarbeit steht bei uns im Mittelpunkt – und genauso feiern wir auch unsere Erfolge: mit regelmäßigen Happy Hours, Team-Ausflügen und unvergesslichen Company Events.
