Senior Python Developer

Styx Intelligence is a fast-growing cybersecurity company based in Vancouver on a mission to make the digital world safer. Our AI-powered platform helps organizations protect what matters most - their brand, executives, and digital assets - by detecting and stopping threats like phishing, impersonation, data leaks, and even emerging risks fueled by generative AI. Backed by top-tier venture investors, we’re building an all-in-one digital risk protection solution that brings together cutting-edge technology, real-time visibility, and automated takedowns. 

At Styx, we move quickly, think boldly, and work collaboratively. Joining our team means having the opportunity to shape the future of online security, solve meaningful challenges at scale, and grow alongside a company that’s just getting started. 

About the Role 

We're looking for a Senior Python Developer to join our growing product team. You'll architect and own backend systems powering real-time data ingestion, large-scale threat detection, and AI-driven analysis. From wiring up LLM pipelines and agentic workflows to building rock-solid internal APIs, your code directly helps clients detect and shut down real digital threats. This role sits at the intersection of backend engineering and applied AI — you'll be expected to move fluidly between both. 

Responsibilities 

• Design and maintain Python-based microservices powering our digital risk protection platform at scale 
• Build and operate data pipelines that ingest, process, and normalize external risk signals — social media,  dark web feeds, web scraping, and more 
• Integrate and orchestrate AI/ML models for tasks like impersonation detection, content classification, and phishing identification 
• Leverage LLMs and agentic AI tools (including Claude and Claude Code) actively in your daily development workflow, not as novelties, but as core productivity and quality levers 
• Design RESTful and event-driven internal APIs to serve frontend teams, analysts, and automation pipelines 
• Collaborate with DevOps on performance, observability, and cloud infrastructure on AWS 
• Participate in architecture decisions, code reviews, and agile development cycles. 

Required Skills 

• 4–5 years of Python development with a strong command of the language, ecosystem, and async patterns 
• MySQL proficiency: schema design, query optimization, indexing strategies, and relational data modelling 
• AWS experience, comfortable deploying and monitoring workloads across EC2, Lambda, RDS, S3, SQS, and related services 
• AI Hands-on experience with AI developer tools — Claude Code, GitHub Copilot, Cursor, or similar; you use AI to write better code faster, not just as autocomplete 
• AI LLM/API integration experience — calling and orchestrating models via APIs (OpenAI, Anthropic, etc.), prompt engineering, and handling model outputs reliably in production 
• Experience building RESTful APIs and working with JSON, webhooks, and async messaging patterns 
• Solid understanding of data structures, performance optimization, and async/concurrent workflows 
• Strong debugging, structured logging, and error-handling discipline 
• CI/CD familiarity and comfort shipping in a fast-paced startup environment 
• Comfortable working in startup-paced environments with evolving requirements 

Nice-to-Haves: 

• Social media API experience — programmatic access to platforms like X/Twitter, LinkedIn, Meta, Reddit, or similar at scale 
• Cybersecurity or threat intelligence background — understanding of attack vectors, OSINT, brand protection, or digital risk 
• ML workflow exposure (scikit-learn, Hugging Face, fine-tuning, or building classification/detection pipelines)
• AI Experience building agentic workflows or multi-step AI pipelines (LangChain, LlamaIndex, custom orchestration) 
• Web scraping, DNS tooling, or OSINT data source integration 
• Experience with Redis, Elasticsearch, or graph databases alongside relational DBs 

 Why Join Styx Intelligence 

• Work on high-impact problems that matter to businesses around the world 
• Small, tight-knit team with a lot of room for ownership 
• Competitive salary and equity package 
• Flexible remote work, generous vacation, and growth opportunities
