Descripción completa del empleo

Leadtech Group builds and scales digital products used by millions of people worldwide. With over 18 years of experience, we bring together multidisciplinary teams to turn ideas into meaningful, high-impact solutions.

Within the group, MAU by Leadtech focuses on subscription-based apps and digital products. It builds on the expertise, technology and product mindset developed at Leadtech, combining proven experience with a strong focus on user value and long-term growth.

Across both brands, we share the same approach: a deep commitment to understanding people and creating experiences that make a difference — for our users and for our teams.

We work as a remote-first, international team, where flexibility and collaboration shape how we build, learn and move forward together. Our environment brings together experienced professionals across product, tech, data and design, all driven by curiosity, ownership and continuous improvement.

If you’re looking to contribute to products with real impact and grow alongside a team that values how things are built as much as what is built, we’d love to meet you.

The role

We are looking for a highly skilled LLM Dev Analyst to design, build, and scale intelligent agents within our Databricks ecosystem, redefining how data is accessed, interpreted, and activated across the organization.

In this role, you will operate at the intersection of AI engineering, analytics, and data platforms, developing domain-specific agents that automate and augment decision-making across key business areas including A/B testing, marketing performance, data engineering workflows, and MarTech processes.

You will translate complex business challenges into agent-driven solutions powered by Large Language Models (LLMs), leveraging both structured and unstructured data to deliver real-time insights and automation at scale.

As a core contributor to our next-generation data stack, you will define and implement best practices for agent architecture, prompt engineering, evaluation frameworks, and orchestration within Databricks, ensuring production-grade reliability and business impact.

Key Responsibilities

1. Agent Design & Development

Design, build, and deploy LLM-powered agents for multiple business domains (A/B testing, marketing analytics, data engineering automation, MarTech workflows)
Develop multi-step reasoning agents that integrate with internal data systems, APIs, and tools
Implement RAG architectures to enable agents to leverage enterprise data effectively

2. Databricks & Data Integration

Integrate LLM agents within the Databricks lakehouse architecture
Build scalable pipelines using PySpark, SQL, and Databricks workflows
Enable seamless interaction between agents and data warehouses, event streams, and APIs

3. Prompt Engineering & Evaluation

Design and optimize prompts, tools, and agent workflows for accuracy and performance
Develop evaluation frameworks to measure agent quality, reliability, and business impact
Implement strategies to reduce hallucinations and improve response consistency

4. Automation & Use Case Delivery

Build agents that automate:
- Experimentation analysis (A/B testing insights)
- Marketing performance reporting and optimization
- Data Engineering workflows and monitoring
- MarTech processes and campaign operations
Deliver solutions that drive measurable efficiency gains and decision velocity

5. Productionization & Reliability

Productionize agent systems with monitoring, logging, and observability
Implement guardrails, security controls, and governance frameworks
Ensure scalability, latency optimization, and cost efficiency

6. Cross-Functional Collaboration

Partner with Data Engineering, Analytics, Marketing, and Product teams
Translate business requirements into scalable AI solutions
Communicate insights and capabilities to both technical and non-technical stakeholders

Requirements

Must-Have Qualifications

Proven experience building applications with Large Language Models (LLMs)
Strong expertise in prompt engineering, RAG architectures, and agent frameworks (e.g., LangChain, LlamaIndex)
Experience with Databricks/Snowflake/GCP, including PySpark and SQL
Strong proficiency in Python
Solid understanding of analytics use cases such as A/B testing, marketing performance, or data workflows
Experience implementing LLM evaluation, monitoring, and guardrails
Strong problem-solving skills with the ability to translate business needs into technical solutions

Nice-to-Have Qualifications

Experience with vector databases (e.g., Pinecone, FAISS, Weaviate)
Familiarity with open-source LLM deployment and optimization (Hugging Face, vLLM, etc.)
Knowledge of MLOps practices, CI/CD, and scalable infrastructure (Docker, Kubernetes)
Experience with MarTech tools (GA4, AppsFlyer, Segment, Braze, Amplitude)
Strong background in experimentation frameworks, causal inference, or incrementality
Experience designing multi-agent systems or autonomous workflows
Understanding of AI product design and human-in-the-loop systems

What We’re Looking For

A builder mindset with a passion for applied AI and automation
Ability to operate in ambiguous, fast-paced environments
Strong ownership and accountability for end-to-end delivery
Curiosity to explore and implement cutting-edge AI capabilities

A pragmatic approach to balancing innovation with reliability
