• Experience working collaboratively with ML or research teams.

• Highly organized, detail-oriented, and dependable.

What We Value

Cyberette is built by a team of people who care deeply about purpose-driven innovation. We

believe in using AI to protect truth, identity, and digital integrity — and data is the foundation

of that mission.

Bonus Skills

• Familiarity with dataset tools (Label Studio, CVAT, Supervisely).

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.

What You'll Do 🚀

• 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 💥 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.) — you don’t need to be a designer
• Background in adtech, performance marketing, or growth
• ClickHouse or similar columnar/OLAP experience

What We Offer 🤗

• 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.
• Annual Offsite: Once a year, we gather for an unforgettable retreat. Expect team-building, relaxation, and a few cocktails under the sun.

About the project

You will be joining an organisation that builds decision-support systems used in environments where reliability and precision are non-negotiable. Their work combines advanced modelling, simulation, optimisation, and machine learning to help organisations operate with confidence under uncertainty. These systems support complex, operationally critical processes where the consequences of good or bad decisions may play out over months or years.

The team you’ll work with consists of individuals with deep experience in engineering, data science, and analytical problem-solving. They operate in high-stakes contexts where clarity, mathematical rigour, and operational awareness matter. Their focus is on building technology that works in the real world — systems that must stand up to ambiguity, incomplete information, and complex constraints.

As a Forward Deployed Engineer, you will be embedded directly into these environments. You’ll sit between engineering teams and domain experts, helping shape solutions, validate ideas, and build the technical bridges that make advanced decision engines work in messy, real-world scenarios.

About the role

As a Forward Deployed Engineer, you will own the technical execution of projects on the ground. When the platform meets real-world complexity, you will be the one who identifies solutions, implements prototypes, builds integrations, and turns abstract models into production-ready components.

You’ll bridge engineering, modelling, and stakeholder needs - helping turn uncertainty into structure, ideas into working systems, and high-level requirements into technical reality.

What you’ll actually do

• Discover opportunities and frame technical problems in complex operational environments.
• Translate ambiguous business requirements into technical specifications and modelling approaches.
• Lead technical conversations with key stakeholders, domain experts, and engineering teams.
• Design and execute proof-of-concepts that demonstrate measurable progress.
• Build bespoke integrations and data pipelines that connect decision engines to client systems.
• Work hands-on with simulation, optimisation, or ML components to customise solutions.
• Contribute to productionisation efforts, working closely with core engineering teams.
• Bridge communication between engineering, modelling, and operational stakeholders.

• Bring structure, clarity, and momentum to high-pressure, fast-changing situations.

   

About you

• You don’t shy away from operational complexity or ambiguous problem spaces.
• You excel at turning real-world challenges into technical models and working systems.
• You have strong foundations in a quantitative field (e.g., Math, Physics, Computer Science, Engineering, Economics, or similar).
• You’re comfortable writing pragmatic, production-aware code (Python experience preferred).
• You understand the difference between experiments, prototypes, and production systems — and can operate effectively at each stage.
• You enjoy working directly with stakeholders, guiding conversations, and making technical ideas accessible to non-technical audiences.
• You’re curious about decision-making, optimisation, simulation, or ML — and motivated to apply these methods to messy real-world problems.
• You can work independently, analyse constraints, propose solutions, and execute quickly.

• You are very good in English and comfortable communicating with senior stakeholders.

   

What you’ll gain

• Real impact: Your work will shape systems that support critical, high-stakes operational decisions.
• Technical growth: Exposure to state-of-the-art optimisation, simulation, and ML techniques.
• Learning: Direct access to senior engineers and technical leaders with deep experience in complex environments.
• Visibility: Meaningful responsibility from day one — including technical decisions and stakeholder interaction.
• Compensation: Competitive salary based on experience.

Working conditions

• Remote role
• Full-time
• Work schedule: 5 days a week, Saturday and Sunday — days off
• Flexible work schedule and autonomy in planning your time
• All payments are made in euros
• An open sole proprietorship or the ability to open one is required
• Paid vacation and sick leave
