About This Role

Als Werkstudent im Bereich Embedded Software Engineering entwickelst du das Herzstück unseres Hausnotrufs: die Firmware. Du bist dafür verantwortlich, dass unsere Algorithmen zur kontaktlosen Notfallerkennung performant und absolut zuverlässig auf der Hardware laufen. Die Stelle richtet sich an Studierende, die sich in der Welt der Register, Interrupts und Echtzeit-Betriebssysteme zu Hause fühlen und Lust haben, komplexe DSP-Algorithmen (Digital Signal Processing) für Audio-Daten direkt auf Mikrocontrollern zu implementieren und zu optimieren.

Aufgaben

Deine Mission ist es, Code zu schreiben, der im Hintergrund Leben schützt. Unser Hausnotruf basiert auf einem innovativen, kontaktlosen Ansatz: Er erkennt Hilferufe und Stürze automatisch über Geräusche. Deine Aufgabe ist es, diese anspruchsvolle Logik auf unsere Embedded-Plattformen zu bringen.

Du arbeitest tief im System an der Firmware-Entwicklung für STM32 oder ESP32 Architekturen. Dabei steht die effiziente Verarbeitung von Audio-Datenströmen im Mittelpunkt. Du implementierst und optimierst DSP-Pipelines, um sicherzustellen, dass die Geräuscherkennung auch unter Ressourcenbeschränkungen (CPU-Last, Speicherverbrauch) präzise funktioniert.

Zudem sorgst du für die nahtlose Integration in unsere Infrastruktur – von der Anbindung der Sensoren über I2S/DMA bis hin zur stabilen Kommunikation nach außen. Du schließt die Lücke zwischen theoretischer Signalverarbeitung und einer robusten, ausfallsicheren Firmware, die 24/7 stabil läuft.

Qualifikation

Du studierst Informatik, Elektrotechnik oder ein ähnliches Fach und brennst für die hardwarenahe Programmierung. C und C++ sind für dich keine Fremdwörter, sondern deine Werkzeuge, um das Maximum aus einem Mikrocontroller herauszuholen. Du hast bereits aktiv mit Plattformen wie STM32 (Bare-Metal oder RTOS) oder ESP32 (ESP-IDF) gearbeitet und weißt, wie man Datenblätter liest, um Peripherie korrekt anzusteuern.

Besonders spannend wird es für dich, wenn Mathematik auf Code trifft: Du hast idealerweise erste Erfahrungen in der digitalen Signalverarbeitung (DSP) gesammelt, zum Beispiel durch die Arbeit mit FFTs, Filtern oder der Vorverarbeitung von Audio-Streams. Du verstehst, wie man analoge Signale digitalisiert und so aufbereitet, dass sie für die Erkennung von Notfällen nutzbar werden.

Du arbeitest strukturiert und hast den Anspruch, dass dein Code nicht nur "irgendwie läuft", sondern effizient, lesbar und wartbar ist. Du hast Freude daran, Fehler mit dem Debugger aufzuspüren und das System Stück für Stück robuster zu machen.

Benefits

    • Zuschuss zum Deutschlandticket
    • Flexible Arbeitszeiten
    • Kostenlose Getränke im Büro
    • Zuschuss zum Internetanschluss
    • Jobrad
    • Betriebliche Altersvorsorge
    • 50 € steuerfreier Sachbezug zum Gehalt
    • Kostenloser Hausnotruf

Das könnte deine Berufung sein, wenn du:

    • Mikrocontroller nicht nur programmieren, sondern ihre Architektur (Register, Speicher, Peripherie) wirklich verstehen willst;
    • bereits Erfahrung mit Real-Time Operating Systems (RTOS) oder Low-Level-Treibern hast;
    • dich für Audio-Processing begeisterst und verstehen willst, wie aus Schallwellen digitale Entscheidungen werden;
    • es liebst, das Maximum aus begrenzten Hardware-Ressourcen herauszukitzeln;
    • Verantwortung übernehmen willst, weil du weißt, dass deine Software in kritischen Momenten funktionieren muss;
    • Lust hast, in einem Team zu arbeiten, das echte Innovation in den Bereich "Ambient Assisted Living" bringt.
