Level:

We're Nomisma, and we're building AI products that actually matter and tools that solve real problems for real people. The next decade belongs to people who can build with AI, not just talk about it. We're looking for engineers who see LLMs, vector databases, and fine-tuned models not as buzzwords, but as raw materials for creation.

If you want to be the person who architects systems, who makes the tough calls, who owns outcomes, not just tickets then keep reading.

First: Who You Are (The Human Part)

We care more about how you think than what you've memorized.

You are:

An owner, not a passenger.

Brutally clear.

Pragmatic over perfect.

Reliable as gravity.

Endlessly curious.

We care about:

• Can you build systems that don't break?
• Can you make intelligent trade-offs?
• Will you level up this team?

What You'll Build (The Tech Part)

You'll work across the full backend stack—from API design to model fine-tuning to production observability. Here's what we expect you to know (or learn fast):

Core Stack

• Backend: Python + one of FastAPI/Flask/Django
• Data: SQL (PostgreSQL/MySQL), NoSQL (MongoDB), Redis, S3
• APIs: REST/GraphQL, clean schema design, authentication (JWT/OAuth2)

AI/ML Tooling

• Frameworks: PyTorch or TensorFlow
• Hugging Face: Transformers, PEFT (LoRA), Datasets
• Embeddings & RAG: FAISS, Pinecone, Weaviate, Chroma
• LLM APIs: OpenAI, Anthropic, Cohere—or open-source alternatives

What You'll Actually Do

No fluff. Real work:

1. Build production-grade APIs that frontend and mobile teams can rely on. Clean contracts. Fast responses. Solid error handling.
2. Architect RAG pipelines from scratch—ingestion, chunking, embedding, retrieval, evaluation. Make them fast. Make them accurate.
3. Fine-tune models (LoRA, QLoRA, full fine-tuning) when pre-trained isn't enough. Optimize inference so it's cheap and responsive.
4. Own observability. Logs, metrics, dashboards, alerts. You'll know when something breaks before your users do.
5. Ship features end-to-end. Work with React/React Native devs to wire up AI features that feel magical to users.
6. Write docs. Clear, kind documentation. Future you will thank present you.
7. Review code. Give thoughtful feedback. Raise the bar.
