About Amara™
We are Amara™, a Berlin-based startup developing an AI-powered companion for older adults. Our product supports cognitive abilities, provides structure in everyday life, and helps people maintain independence and safety for as long as possible. In a small, fast-moving team, we work at the forefront of applied AI, building technology with clear social relevance. AI is central to both our product and how we work every day.
Your Mission
You will own the backend foundation of our voice-driven, AI-first product. As one of our earliest engineering hires, you'll architect scalable APIs and real-time audio systems, integrate cutting-edge LLMs and audio models, and work directly with the founding team to shape the technical direction of Amara™. This is a high-ownership role for someone who thrives at the intersection of Python, AI, and audio engineering.
Your Responsibilities
Backend Architecture: Design and build robust backend services in Python (FastAPI) and real-time audio pipelines (RTC / Streaming)
LLM & Audio Integration: Integrate LLMs, embeddings, and audio models (e.g., Whisper, ElevenLabs, Coqui, OpenAI, local inference)
Voice AI Development: Develop modular voice AI and intelligent conversation flows using LangChain
API Design & Collaboration: Work closely with frontend engineers (FlutterFlow / React Native) on API design and data flows
Database & Auth Management: Implement and maintain Supabase for authentication, database, and storage
Infrastructure & CI/CD: Build and maintain CI/CD workflows (GitHub Actions, Docker, Kubernetes / AWS)
Model Orchestration: Collaborate with AI researchers and voice engineers on model optimization and orchestration
Your skill set
Strong Python background with production experience in FastAPI or similar frameworks
Experience integrating LLMs or audio models (TTS, STT, voice cloning) — or a strong drive to learn it quickly
Solid understanding of software architecture and design patterns
Familiarity with Supabase, PostgreSQL, and vector databases (e.g., Pinecone, Weaviate, PGVector)
Understanding of LangChain, RAG, embeddings, prompt pipelines, and memory systems
Hands-on experience with Docker, CI/CD, and modern cloud setups (AWS)
Bachelor's degree in Computer Science or a related field
Bonus: Familiarity with Flutter, LiveKit, PyTorch, Mixpanel, Sentry
Startup DNA: hands-on, iterative, results-driven
Fluency in English, written and spoken
Essential Skills
Python, Docker, PostgreSQL, Audio, LLMs, Large Language Models, AI
