Stockholm, Sweden Helicon Technologies Full time
Om oss

#LI-Hybrid

Helicon utvecklar mjukvarulösningar för startups och större företag inom energisfären (t.ex. ABB, Polarium, Stockholm Exergi och Hitachi Energy). Våra erfarna utvecklare och data scientists är experter på produktutveckling, datahantering och molnlösningar.

Ett typiskt projekt för oss innehåller någon slags datainfrastruktur (där vi ofta använder verktyg som Kubernetes, Airflow, PostgreSQL, TimescaleDB, InfluxDB eller Kafka), en maskininlärningskomponent (oftast byggd med Spark och Tensorflow), APIer och kod för att sköta kommunikationen mellan tjänster (t.ex. Python, FastAPI, Django, Kafka, RabbitMQ), och en UI-lösning där slutanvändaren kan styra systemet och visualisera data och analyserna (t.ex. React, ThreeJS, WebGL).

Om dig
  • Du älskar att koda och teknik i allmänhet.
  • Du är näst intill flytande i Python och gärna även erfarenhet av Django.
  • Du gillar att upptäcka, definiera och lösa problem.
  • Du kan göra pragmatiska beslut kring estimering och kravställning, och kan förklara varför teamet arbetar på ett visst sätt.
  • Du löser tekniska utmaningar tillsammans med ditt team, och ser samtidigt till att ni alla växer kompetensmässigt.
  • Du kan tänka teoretiskt och i abstraktioner, men förstår värdet av att leverera något konkret och få saker gjorda.
  • Du har en bra balans mellan att arbeta snabbt och att skapa underhållbar och skalbar kod.
Om rollen
  • Agera mentor och hjälpa teamet utveckla sin kompetens inom backendutveckling.
  • Snabbt och precist planera och leverera på projekt kring backendutveckling.
  • Genomföra code reviews på ett konstruktivt och positivt sätt, och ge meningsfull feedback
  • Bygga och leda backend-team och -initiativ.
Vad vi letar efter
  • 5+ års erfarenhet av en relativt modern backend-stack.
  • Erfarenhet av AWS och/eller Azure.
  • Du skriver kvalitativ kod som är lätt att läsa, förstå och testa.
  • Bra förståelse av Docker och Git.
  • Goda kunskaper inom profilering och prestandaoptimering.
  • Ledarerfarenhet och bra på att kommunicera effektivt.
  • Arbetstillstånd inom EU.
Bonus
  • Erfarenhet av en eller flera av verktygen vi ofta använder: Kubernetes, Spark, Airflow, Kafka, Timescale, Tensorflow, Keras.

About you

  • You’re pretty much fluent in Python, and preferably also got experience with Django.

  • You make pragmatic scoping decisions and can explain why the team is doing something a certain way.
  • You work with your team to tackle technical challenges and to level up in the process.
  • You can theorize and think in abstractions, but understand the importance of getting things done.
  • You strike a balance between moving fast and creating scalable and maintainable solutions.
About the role
  • Provide mentoring and push the team forward in terms of back-end development methodologies.
  • Rapidly and precisely plan and execute back-end application development projects.
  • Perform positive code reviews and provide meaningful feedback.
  • Build and lead back-end development teams and initiatives.
What we are looking for
  • 4+ years of experience with a reasonably up-to-date back-end stack.
  • Experience with running deployments on AWS and/or Azure.
  • You write high-quality code that is easy to read, understand, and test.
  • Strong understanding of Docker and Git.
  • Fundamental understanding of profiling and performance optimization.
  • Leadership experience and strong communication skills.
