What we’re looking for:

SurveyMonkey's Machine Learning organization spans two connected tracks: the Machine Learning Platform (MLP) team, which builds the secure, scalable pipelines and infrastructure that deploy and monitor ML models in production, and the Product Data Science team, which designs, builds, and fine-tunes the models, from statistical methods to LLMs, before they reach deployment. We're building enterprise-scale NLP and ML systems, and looking for talented ML engineers at different levels, from early career through to Staff Engineer. Whether you're a technical leader ready to shape our ML architecture and mentor teams, or an engineer looking to own end-to-end ML solutions, we have roles that could fit.

You'll work at the intersection of Data Science, DevOps, and Product, helping power technologies like Generative AI, NLP, and real-time classification across SurveyMonkey's product portfolio.

What you’ll be working on:

• Build and own end-to-end ML/AI solutions within the product, maintaining long-term ownership through different stages of deployment, refinement, and iterative enhancements

• Build end-to-end monitoring and telemetry systems to detect complex failure modes, deterioration of predictive accuracy, and usage patterns.

• Architect scalable ML platforms and production data pipelines, collaborating cross-functionally to integrate new data sources.

• Create novel and traditional ML/AI implementations for the in-product experience, collaborating with Product, Design, Front- and Back-End developers to educate teams and iterate through solutions and designs.

• Deliver tailored AI solutions by training, fine-tuning, and deploying models ranging from statistical methods to cutting-edge LLMs.

• Drive continuous improvement and innovation through research, proposing adoption strategies for external solutions, identifying knowledge gaps within the team, and ensuring hiring and training initiatives address capability needs.

We’d love to hear from people with:

• Extensive professional experience in Machine Learning and Data Science, building and maintaining models in production environments.

• Strong expertise in Natural Language Processing, statistical modelling and analysis, and modern ML methods. Deep understanding of not just the models, but what's happening within them—hands-on experience building novel architectures for bespoke product solutions.

• Experience handling data at scale with familiarity in Human-In-The-Loop labelling, training and scaling usable data, plus foundational exploratory data analysis.

• Proven expertise in creating evaluations and evaluation platforms for non-deterministic systems, including LLM-as-Judge techniques, inferred signals, and traditional model evaluation mechanisms to validate performance and maximise ML/AI impact.

• Experience developing production monitoring and creating feedback loops using active feedback, passive signals, and user behaviours to identify key performance indicators for user journeys and experiences.

• SaaS development and deployment experience, building multi-scaled, right-sized ML solutions in SaaS environments with CI/CD code lifecycle practices in AWS environments and services (Kafka, EKS, SageMaker, Athena).

• Demonstrated experienc...
