About the Role
A1 is building a proactive AI system that understands context across conversations, plans actions, and carries work forward over time.
As an Applied AI Engineer, you will turn model capabilities into real product behavior. You will own problems end-to-end, from shaping model behavior, to building the systems around it, to ensuring it performs reliably in production.
This role sits at the intersection of machine learning, systems, and product, focusing on making AI actually work for users, not just in demos, but in real-world usage.
Focus
- Build and ship AI features end-to-end (model → system → user experience)
- Design and iterate on prompts, tools, memory, and agent workflows
- Turn raw model outputs into structured, reliable, and predictable behaviors
- Debug issues across the full stack (model, orchestration, infra, UX)
- Optimize for latency, cost, and production reliability
- Develop lightweight evaluation frameworks to measure real-world performance
- Work closely with product and engineering to translate ambiguous problems into working systems
Tech Stack
- Python
- PyTorch / JAX
- LLMs (OpenAI‑style APIs, LLaMA, Qwen, etc.)
- Inference / serving (e.g. vLLM)
- Vector DB
Ideal Experience
- Strong foundation in machine learning and modern neural network architectures.
- Hands‑on experience with training, fine‑tuning, or deploying ML models
- Ability to write clean, production‑quality code
- Comfort working across abstraction layers (model → infra → product)
- Strong problem‑solving skills in ambiguous, fast‑moving environments
- Bias toward shipping, iteration, and continuous improvement
Outcomes
- ML models in production meet expected accuracy, latency, and reliability targets.
- Production issues are identified quickly, debugged effectively, and root causes addressed.
- Data pipelines, training loops, and inference systems are robust, reproducible, and maintainable.
- Collaborates effectively with engineers, product, and research teams to deliver reliable ML‑powered features.
- Iterations on models and systems are driven by real‑world signals and measurable improvements.
