We are seeking a Principal Engineer to join the founding team of our Performance Affiliate Network platform.
This is a high-impact role where you will lead architecture decisions, own system-level technical strategy, and deliver key features across an AI-integrated affiliate tech stack.
You'll work closely with Product, Growth, and other engineering teams to build resilient systems that scale for use cases like agent-based automation, channel integrations, and data ingestion.
Responsibilities
Design and develop full-stack features using TypeScript (NestJS, NextJS, React) and Python
Lead the implementation of microservices and event-driven orchestration patterns to support data-rich, real-time affiliate workflows
Architect and deploy AI agent systems using frameworks like LangChain, custom RAG pipelines, and vector databases
Build and maintain web scraping pipelines using Apify or custom frameworks, ensuring reliability, throughput, and compliance
Integrate bots and connectors across messaging and web platforms (e.g., Discord, Telegram)
Ensure observability (metrics, logs, traces), CI/CD health, and secure cloud infrastructure (AWS + Terraform, GitHub Actions, Argo CD)
Drive internal technical quality through unit testing (= 80% coverage), functional testing, and end-to-end testing, while actively managing critical technical debt
Collaborate with the Tech Lead and non-technical teams through pair programming, reviews, and demos
Evaluate and incorporate emerging technologies in AI, LLMs, and automation to continuously improve product capabilities
Requirements
5+ years of full-stack experience building and scaling production-grade web platforms
Expertise in TypeScript (Node.js, NestJS, React) and proficiency in Python (FastAPI)
Hands-on experience with AI agent frameworks (e.g., LangChain), vector stores, and RAG workflows
Proven ability to design and deploy scalable scraping systems using tools like Apify
Familiarity with messaging or bot development ecosystems (e.g., Discord.js, Telegraf)
Solid understanding of relational (PostgreSQL) and non-relational (e.g., MongoDB) databases; comfortable modeling for both transactional and unstructured data
Experience building event-driven architectures using Kafka, Kinesis, RabbitMQ, or similar
Strong debugging, profiling, and performance optimization skills across the full stack
A degree in Computer Science, Engineering, or a related technical field is preferred
Nice to Have
Experience in affiliate, fintech, gaming, or other high-compliance domains
Exposure to LLMs, embeddings, vector search (e.g., Pinecone), and tool/agent chaining logic
Familiarity with observability tooling (Grafana, Prometheus, DataDog) and incident response practices
Knowledge of privacy, data compliance, and secure coding standards (e.g., GDPR, ISO 27001)
Proficiency with CI/CD, infrastructure-as-code (Terraform), and cloud-native deployment on AWS
Contributions to open-source AI or development projects
