Sr. Product Engineer

About Venxr
VenXR is an AI-driven AdTech startup building AdsGPT, redefining how brands plan, execute, and optimize ad campaigns through AI. We're a fast-growing, lean team looking for a Product Engineer who can own features end-to-end, from idea to shipped product.
About The Role
We're looking for a Product Engineer who thinks like a builder, not just a coder. Someone who cares as much about why we're building something as how it's built, and takes real ownership of the product outcomes, not just the code they ship.
Tech Stack
Frontend: React.js | Backend: Python (Django) | AI: Claude / LLM-driven development
Roles & Responsibilities
End-to-End Feature Ownership Own features from concept to deployment — writing clean, scalable code while staying closely tied to the product goal and user impact behind it.
Full-Stack Development Build and maintain front-end interfaces in React.js and back-end systems in Python/Django, ensuring performance, reliability, and scalability across the product.
Product Thinking Work closely with Product, Design, and Founders to shape specs, question assumptions, and suggest simpler or smarter ways to solve user problems.
Rapid Iteration Ship fast, test in production, gather feedback, and iterate, balancing speed with code quality.
Cross-Functional Collaboration Partner with Design and Data teams to bring dashboards, AI-driven features, and data visualizations to life.
System Design & Architecture Contribute to technical architecture decisions, ensuring the codebase stays scalable as the product and team grow.
Debugging & Problem Solving Diagnose and resolve complex technical issues quickly, treating downtime or bugs as urgent, customer-impacting problems.
AI-Native Development Actively build with AI — using Claude and other LLM tools not just to assist coding, but to develop AI-powered features, prompt workflows, and intelligent product capabilities within AdsGPT itself.
Requirements
2–4 years of experience as a Product Engineer, ideally in a startup or B2B SaaS environment
Strong proficiency in React.js for front-end development
Strong proficiency in Python, with hands-on experience in Django for back-end development
Solid understanding of REST APIs, databases (SQL/NoSQL), and system design fundamentals
Hands-on experience building with AI tools (like Claude), not just using them for coding assistance, but developing core AI products.
Experience working directly with Product/Design teams, not just executing tickets
Comfortable working in ambiguous, fast-changing environments with minimal hand-holding
Strong debugging and problem-solving skills
Good to Have
Familiarity with the Model Context Protocol (MCP) for securely connecting LLMs to external tools and APIs.
Experience building conversational AI interfaces or managing complex multi-turn chatbot state across various platforms and channels.
Experience in AdTech, MarTech, or data-heavy SaaS platforms.
Exposure to cloud infra (AWS/GCP/Azure), Docker, and CI/CD pipelines.
Experience with LLM evaluation/monitoring tools (Ragas, LangSmith, Langfuse, or similar).
Experience with data visualization libraries (Recharts, D3.js, Chart.js).
Familiarity with compliance-aware or explainable AI design in regulated domains.
What We Look For In Candidates
Customer Obsession – A genuine curiosity about how your code impacts the customer's experience, not just whether it compiles.
Ownership – You drive features to completion, chasing down blockers instead of waiting on them.
Stakeholder Understanding & Management – You know when to loop in Product, Design, or Business to unblock yourself fast.
High Standards – You hold your own code to a higher bar, even when no one's checking.
Disagree and Commit – You debate technical decisions hard, then commit fully once the call is made.
Simplify Relentlessly – You reach for the simplest working solution, not the most "clever" one.
Solidarity with the Team – You show up for your teammates, no invitation needed.
Vitality – You bring real energy and resilience that keeps you (and others) going.
