Хелоу, люба спільното \0/

Ми продовжуємо нарощувати команду американського Survey SaaS, що аналізує поведінку юзерів під час digital опитувань. По суті, це платформа, де бізнес може засетапити своє опитування та отримати швидкий результат, очищений від ботів + отримати advanced behavioural analytics від нашої моделі.

Вам сподобається, якщо ви:
- самодостатні та организовані.
- хочете автономію та відповідальність за свою ділянку.
- вам дійсно цікаво те, чим ви займаєтесь.

На цьому я дозволю перемкнутись на англійську, бо далі конкретніше.

About the role

Build and own ML models that predict survey respondent certainty and detect fraud from behavioral signals — mouse movement, click patterns, timing, browser/OS data. You'll be the sole ML engineer maintaining a production hybrid CNN+tabular certainty model (already in client deliverables) and building the new bot detection model. You'll work directly with a US-based AI scientist who provides strategic direction.
 

What you'll work on

• Improve the hybrid 1D CNN (mouse trajectories) + MLP (tabular features) certainty model — error analysis, hyperparameter tuning, augmentation, loss experiments 
• Build the bot detection classifier — binary human/bot model reusing behavioral pipeline infrastructure 
• Run segment-level evaluations — per-survey quality checks, precision/recall optimization, calibration analysis 
• Track experiments in MLflow — every run logged with parameters, metrics, dataset versions 
• Process raw time-series — mouse trajectories as [T, 7] tensors (x, y, speed, acceleration, dt, dx, dy) 
• Document to audit standard — code, dataframes, notebooks, reproducible results with artifact links
   

What we're looking for

• Strong PyTorch — built and trained CNNs from scratch, not just fine-tuned 
• Tabular ML experience — LightGBM, XGBoost, or gradient boosted trees 
• Rigorous evaluation mindset — calibration, segment analysis, label quality, beyond single-metric optimization 
• Time-series/sequence data experience — temporal patterns in any domain (NLP, audio, sensors, clickstream) 
• Imbalanced classification expertise — precision/recall tradeoffs, threshold tuning, AUC-ROC 
• MLflow or similar (W&B, Neptune) 
• Self-directed — you're the only ML person on execution, strategic guidance from US AI scientist 
• Auditable work — advisor reviews regularly, notebooks/scripts must be clean
• Clean verbal English
   

Nice to have

Behavioral/clickstream analysis • time-series augmentation • fraud/anomaly detection • model serving • survey methodology/psychometrics
 

Stack

Python • PyTorch • LightGBM • MLflow • HDF5 • PostgreSQL
 

What this is NOT LLM/GenAI role, but classical ML + deep learning on structured behavioral data 

The Team

• Product Manager
• 2x Fullstack Devs
• Anti-Fraud Automation QA
• DevOps
   

We offer

• 20 paid day-offs per year.
• 10 US/UA holidays.

About LUML
LUML is building the all-in-one ML platform for teams that don't have (or want) a dedicated platform team. Our open-source tool, LUMLFlow, gives ML engineers experiment tracking that just works. The LUML Platform adds a cloud registry, one-click deployments, and monitoring - everything a growth-stage ML team needs to go from notebook to production on day one.

We're looking for a developer marketing manager to own LUML's content, outreach, and growth channels. You'll work directly with the founding team to build awareness among ML engineers, grow our open-source community, and drive adoption of both LUMLFlow and the LUML Platform.

What You'll Do
 

• Create technical content (tutorials, migration guides, comparison posts) that resonates with ML engineers
• Manage social media across LinkedIn, Twitter/X, and developer platforms in an authentic engineer voice
• Execute developer outreach: Hacker News launches, Reddit engagement, GitHub community building
• Run targeted LinkedIn campaigns aimed at engineering managers
• Track channel performance and funnel metrics to identify what's working

Must-Haves
 

• Experience marketing developer tools or technical SaaS products
• Strong technical writing - tutorials an engineer would actually follow, not marketing fluff
• Experience with bottom-up / product-led growth motions
• Hands-on social media and content experience for technical audiences

Nice-to-Haves
 

• Experience marketing ML/data infrastructure or open-source projects specifically
• Familiarity with MLOps tools (MLflow, W&B, SageMaker) - ideally hands-on
• Experience with paid LinkedIn campaigns targeting technical buyers
• Portfolio of Show HN launches or open-source community growth
• Video content creation (demos, YouTube, short-form)
• Bottom-of-funnel SEO for developer tools
