About Reacher:

We're the

#1 TikTok Shop partner

helping brands like Under Armour, Hanes, HeyDude, and Logitech scale their affiliate marketing. We've crossed

7 figures in ARR , and are rapidly scaling our team this year. Our vision is to become the

Hubspot for creator marketing , powering brands and creators to connect and grow across all commerce platforms (Youtube Shopping, Instagram Shopping, Shopify, Amazon).

We're building key infrastructure for the creator economy and implementing

AI with the world's largest brands and creators . Your work will

directly impact users on day 1 -our user base depends on our product daily.

Your work will directly impact users on day 1.

We have a highly responsive user base that depends on our product day in and day out.

What You'll Do Own ML systems end-to-end : research, prototype, train, deploy, and iterate rapidly Build multimodal ML systems

for video, text, images, and audio at scale Design and deploy LLM-powered applications

using RAG and AI APIs Develop content understanding and classification models

for text and visual data Build search and discovery systems

using embeddings and semantic retrieval Create audio analysis and processing pipelines Build MLOps infrastructure -data pipelines, model serving, monitoring, and experiment tracking Ideate ML/AI product features

with product and customers Leverage modern AI tools

to accelerate development Work directly with customers and translate vague requirements into shipped ML solutions Ship fast and learn fast -high urgency environment You're a Fit If You have

4-7 years of ML engineering experience

building and deploying models in production You have

strong Python and ML fundamentals

and write clean, maintainable production code You've

built ML models end-to-end : data pipelines, training, serving, monitoring You're

experienced with modern ML frameworks

(PyTorch, TensorFlow, scikit-learn) You have

production experience with LLMs and AI APIs

(OpenAI, Anthropic, Hugging Face) You can

build ML systems across multiple domains -NLP, computer vision, and audio You're

product-minded

and identify where ML can solve user problems and improve business metrics You're

comfortable with MLOps tools

and cloud platforms (AWS or GCP) You're resourceful and

thrive in ambiguous environments ML & AI-Specific Skills We Value Core ML : Supervised/unsupervised learning, feature engineering, model evaluation, A/B testing Deep Learning : Neural networks, transformers, CNNs, training and optimization NLP/LLMs : RAG systems, prompt engineering, vector databases, fine-tuning, LangChain Computer Vision : Image classification, object detection, OCR, visual content understanding, image embeddings Audio/Speech : Audio classification, speech recognition (ASR), audio transcription Search & Retrieval : Semantic search, embedding models, vector similarity, multimodal retrieval MLOps : Model serving, monitoring, experiment tracking (MLflow, Weights & Biases), data pipelines Cloud ML : AWS (SageMaker, Bedrock) or GCP (Vertex AI), model deployment, scalable inference Bonus Points If You've worked at an

early-stage startup

or been a

first/early ML hire You have experience building

multimodal search systems

or semantic retrieval at scale You have experience with

video understanding -extracting features, generating embeddings, or analyzing visual content You've implemented

feature stores

or advanced MLOps infrastructure You have experience with

real-time inference and low-latency model serving You have expertise in

adversarial robustness

and model safety testing You've built

hybrid RAG + fine-tuning systems You have experience with

multimodal models

(vision + language, audio + text) You're experienced with

model optimization

(quantization, distillation, pruning) You have a track record of

shipping ML-driven product features

that moved key metrics You've shipped side projects or contributed to open-source ML projects Why Join Us Post-revenue company solving

real problems for real customers Be the ML/AI leader -define our ML strategy and infrastructure as we scale High autonomy and visibility -no boring tickets Your models reach users

within days, not months Strong

engineering-first culture Shape both the product and the company Work on diverse ML problems across video, language, and audio Direct impact on product strategy -your ML ideas become features When Applying:

Feel free to send a short note about

something you've built

and

why this role excites you . GitHub/LinkedIn/resume is great, but we care more about

how you think and build !
