Mar del Plata, Buenos Aires, Argentina Celara A tiempo completo $900.000 - $1.200.000 al año

Celara is a fast-growing technology company delivering transformative AI solutions for innovative startups and fast-moving enterprises. We're looking for a Senior AI Engineer who thrives in startup environments — someone who can move fast, wear multiple hats, and help architect and build AI systems from the ground up. This is a high-ownership role, ideal for a technical builder with a product mindset and a passion for figuring things out in real time.

What You'll Do

  • Start by building foundational AI capabilities and products, with opportunities to grow into leading teams and larger initiatives as they scale
  • Lead the design and development of end-to-end AI applications — from prototype to production
  • Work closely with founders, clients, and other engineers to shape both technical and product direction
  • Build and deploy LLM-based systems, including RAG pipelines, fine-tuned models, and embedding search
  • Own delivery of real-world solutions: architect, implement, test, ship
  • Iterate rapidly: explore new tools, try new ideas, and solve problems creatively
  • Operate with autonomy in a fast-changing environment — sometimes as the only engineer on a project
  • Occasionally, dive into adjacent areas like frontend, dev tooling, or data pipelines as needed

Must-Have Skills

  • Strong experience with modern AI techniques — LLMs, prompting, fine-tuning, RAG, vector databases
  • Strong Python engineering background, with clean, modular coding practices
  • Comfortable building systems in a solo or small-team setting with limited structure
  • Familiarity with cloud deployment (AWS/GCP), Docker, and production ML pipelines
  • Able to balance product thinking and engineering discipline
  • Startup mentality: comfortable with ambiguity, fast iteration, and wearing many hats
  • Excellent communication skills — able to work directly with clients and non-technical stakeholders

Bonus Skills

  • Experience in Conversational AI and Voice AI systems
  • Knowledge of ML frameworks (PyTorch, scikit-learn, etc.)
  • Exposure to frontend (JS/React) or dev tooling is a plus
  • MLOps / CI/CD familiarity
  • Prior experience in early-stage startups

Why Join Celara?

  • Work on real AI problems across industries — voice, analytics, automation, and beyond
  • High autonomy, high-impact role on a lean, ambitious team
  • Shape both the product and technical foundation of AI systems
  • Flexible remote-first culture with occasional in-person collaboration in Buenos Aires
  • Competitive compensation based on experience and ability
  • Continuous learning, experimentation, and exposure to cutting-edge AI tools
