Jobs at Cantina Labs

The Financial Analyst will manage accounts payable from invoice intake through payment, including expense coding, payment cycles, AP aging, vendor schedules, reconciliations, accruals, and financial reporting. The role will investigate discrepancies, support month-end close, improve cross-functional purchasing processes, and automate finance workflows. Over time, the analyst will contribute to cash forecasting, budgeting, financial analysis, and finance systems projects.

Own the architecture, roadmap, and production operation of search and recommendation systems across discovery surfaces. Lead retrieval, ranking, personalization, relevance measurement, experimentation, OpenSearch infrastructure, signal pipelines, and candidate generation. Partner with Product, Data, ML, and Trust & Safety to balance relevance, freshness, safety, latency, and cold-start behavior. Establish engineering standards, instrumentation, rollout processes, and runbooks while mentoring backend engineers.

Conduct research on next-generation video generation models, focusing on distillation, inference efficiency, reward modeling, preference optimization, evaluation, and scalable training infrastructure. Interns will formulate hypotheses, run large-scale experiments, analyze results, develop research tooling, and communicate findings through reports, presentations, demonstrations, and potential conference submissions under senior mentorship.

Three-month onsite internship developing and evaluating video-generation machine learning systems. Projects may involve reward modeling, inference efficiency, multimodal data pipelines, distributed training infrastructure, large-scale experimentation, and evaluation tooling. Interns own a defined research or engineering project with senior mentorship and may contribute to conference publications or product-adjacent work.

Build and productionize large-scale TTS and adjacent speech models end-to-end: model architecture, training, alignment, evaluation, data curation, distributed GPU scaling, latency/cost profiling, tooling, and safety/mitigation for speech systems.

Design, deploy, and scale low-latency inference infrastructure for generative audio models (TTS, ASR, voice conversion). Build high-performance inference engines, Kubernetes-based autoscaling, CI/CD pipelines, observability, and GPU optimization to bridge research and production for streaming and batch workloads.

The ML Engineer will build and scale large-scale data systems and pipelines, focusing on workload orchestration, dataset curation, and quality improvement techniques for machine learning models.

Own Cantina’s lifecycle product strategy across email, push, and in-product messaging. Develop onboarding, activation, retention, resurrection, and monetization journeys; analyze funnels, cohorts, and qualitative signals; run experiments; and partner with Data and Engineering on instrumentation, personalization, triggers, deep links, dashboards, and post-click experiences. Establish lifecycle operating standards, optimize messaging portfolios, and communicate multi-quarter strategy and tradeoffs to senior stakeholders.

The Product Director will lead the video product strategy and execution, collaborating with teams to enhance creators' video content creation and sharing experience.

Lead iOS application development, create innovative features, collaborate with cross-functional teams, and ensure high-quality standards in a supportive environment.

The role involves designing and developing model evaluation pipelines, user studies for subjective evaluations, and automated dashboards to report results, alongside leading the evaluation team and communicating with other teams to improve model performance.

As a Product Manager at Cantina, you will oversee the web product's roadmap, collaborate with global teams, and define user workflows for video editing.

Build and ship state-of-the-art speech systems end-to-end: model architecture, training (pre-train/fine-tune/post-train), evaluation, tooling, data curation, production inference, and safety/abuse mitigation for voice conversion and related tasks.

Lead creative strategy and scaled production for paid performance campaigns across Meta, TikTok, YouTube and mobile ad networks. Develop concept-driven, high-volume creative pipelines using traditional and AI-generated production, own performance analytics and testing frameworks, manage agencies and cross-functional teams, and establish QC processes to iterate on creatives that lower CPIs and drive user acquisition and engagement.
