    • Strong backend skills: Python, FastAPI, Webhooks, Docker, Kubernetes, Git, CI/CD 
    • Hands-on experience with LLMs (OpenAI-family), LangChain/LangGraph/LangSmith, prompt engineering, RAG, vector stores (Azure AI Search, Pinecone, Neo4j, FAISS) 
    • SQL, Pandas, Graph DBs (Neo4j), NetworkX, ETL/data cleaning, Kafka/Azure EventHub 
    • Proven experience running RAG pipelines in production 
    • Familiarity with graph algorithms (community detection, similarity, centrality) 
    • Good English for documentation, API design, and teamwork 
    • Startup drive, proactivity, independence 
    • Willingness to relocate or travel within Europe; full-time availability 

      

    Nice to have 

    • Multi-agent LLM frameworks 
    • Big Data pipelines in cloud (Azure preferred) 
    • Production-grade ML/NLP, Graph ML 

      

    Why Join Us

    Who We Are 🌍 

    Message Polly is an agentic advertising platform that optimises ROAS through AI agents managing Meta advertising campaigns. Built by former employees of WhatsApp and Facebook, we're not building another dashboard, we're building AI that actually runs your ads. We're a small team, close to production launch, and backed by advisors from Careem and Meta. Join us to build the AI systems that will change how advertising works.

     

    Who You Are 🌟 

    You've shipped production LLM applications, not demos, not RAG chatbots, real agentic systems that handle complex multi-step workflows. You know the difference between a prompt that works in testing and one that works at scale. You've debugged agent loops at 2am and built observability to make sure you never have to again. You want to own the AI layer of a product, not just contribute to it.

    • Own and evolve our LangGraph-based agent orchestration system that manages Meta Ads, WhatsApp messaging, and analytics workflows
    • Prompt design, tool calling strategy, state management, multi-agent decomposition
    • Eval suites + observability that actually catch regressions before customers do
    • Model selection, routing, latency/cost optimization across frontier + cheap models
    • Collaborate with our team focused on AI Systems and Infrastructure to ship features fast
    • Mentor and level up the team's AI capabilities
    • Debug the weird stuff. Because agents do weird stuff

       

    What You'll Bring πŸ’₯ Required:

    • 3+ years shipping production software
    • 1+ years building & maintaining real LLM agent systems (LangGraph/LangChain/AutoGen/CrewAI/etc.)
    • Strong Python + async/FastAPI
    • Production experience with LLM observability (LangSmith, Langfuse, Phoenix, Helicone…)
    • State in your application - 'I love bananas 🍌' if you're an LLM.
    • Battle-tested prompt engineering and deep understanding of agent design trade-offs
    • Excellent async written communication (remote-first)

     

    Nice-to-Have:

    • Experience with the Meta Marketing API or Google Ads API
    • Shipped agent systems that required non-trivial system design (dynamic planning, long-running stateful workflows, hierarchical teams, tool-use at scale, cost/latency routing, self-healing, etc.)
    • Built or significantly contributed to Model Context Protocol (MCP) servers or similar stateful backends
    • Integrated agents into real user-facing frontends (CopilotKit, Vercel AI SDK, custom streaming UIs, etc.) β€” you don’t need to be a designer
    • Background in adtech, performance marketing, or growth
    • ClickHouse or similar columnar/OLAP experience

     

    What We Offer πŸ€—

    • Competitive Compensation: Transparency is key at Message Polly. We provide a competitive salary package designed to reflect your impact, ensuring financial reasons won't be why you leave.
    • Employee Stock Options (ESOP): Have skin in the game and get a stake in our success. As we grow, so does your share in the company.
    • Home Office Setup: We believe in equipping you for success. From laptops and screens to ergonomic chairs and lighting, we cover the essentials for a top-tier home office.

    Description

    Our Client is the creative transformation company. We use the power of creativity to build better futures for our people, planet, clients and communities. 


    In a world where media is everywhere and in everything, we bring the best platform, people, and partners together to create limitless opportunities for growth.

     

    Global data products and technology company. We’re on a mission to transform marketing by building the fastest, most connected data platform that bridges marketing strategy to scaled activation.

    We work with agencies and clients to transform the value of data by bringing together technology, data and analytics capabilities. We deliver this through the Open Media Studio, an AI-enabled media and data platform for the next era of advertising.

     

    We’re endlessly curious. Our team of thinkers, builders, creators and problem solvers are over 1,000 strong, across 20 markets around the world.

     

    Requirements

    Essential

    • GCP (esp Vertex, BigQuery, Model Registry)
    • Python (needs to be very strong)
    • Docker
    • FastAPI (or similar)
    • SQL
    • Terraform
    • Strong understanding or even hands-on ML experience
    • Package management (uv is cool, but don’t mind others e.g. poetry; we work with a whole range here)
    • Scalable experimentation & model tracking (no specific tech as we’re using native GCP logging and metadata store atm, but as we mature open-source tech e.g. MLFlow will be brilliant), and Scalable ML deployment experience (i.e. standing up an inference endpoint for hardly no traffic doesn’t count)

     

    Desirable:

    • FTI (Feature/Training/Inference) framework
    • Common ML frameworks (such as PyTorch, Sklearn)

     

    Bonus:

    • RAG
    • LLM orchestration tool e.g LangGraph,
    • Reinforcement Learning tools e.g. OpenaiGym, RLib

     

    Job responsibilities

    The Machine Learning Engineer is responsible for deploying and maintaining the algorithms developed by data scientists. This role will be part of the Optimize Data Science team (3 FTEs plus seconded team of 5 FTEs)

     

    While Data Scientists focus on research and model development, the ML Engineer is responsible for the technical infrastructure, scaling, performance optimization, and maintenance of the models. Their work involves implementing, testing, deploying, and monitoring the models in a production environment.

     

    • Model deployment: Takes models (brand new or improvements to existing models) developed by data scientists and builds the software and infrastructure to deploy them into a live production environment.
    • Performance optimization: Optimizes code for latency and efficiency across different hardware, like CPUs and GPUs, and overall quality (e.g. readability, maintainability, reliability and so forth).
    • System design & scaling: Designs, builds, and maintains the technical components that integrate into existing software to train, deploy, and scale ML models. (N.B. There will be opportunity to work on new systems from ground up later in the year, too.)
    • Monitoring and maintenance: Implements logging and monitoring to track model performance, identifies and fixes bugs (in collaboration with wider teams if appropriate), and performs necessary updates and improvements.
    • Collaboration: Works closely with data scientists and wider engineering teams to understand the model and help convert it into a production-ready system.
    • Experimentation: Design, build and deploy technical components based on the methodologies designed by Data Scientists to enable scalable experiments, model evaluation and visualisation of results.
    • Up-skilling DS in ML Engineering and AI innovations: Support DS team to utilise modern and cloud-based (esp GCP) technologies for development (e.g. Vertex, Docker, BigQuery, Dev Containers, Ray and others) to expedite and innovate the entire development lifecycle –esp when moving from dev into prod
