Senior Software Engineer

QuoIntelligence

Role Description Mercury is QuoIntelligence's Threat Intelligence platform: it processes over 2 billion signals, tracks 400+ threat actors, and delivers finished intelligence to security teams across financial services, energy, and government in Europe. You will join a four-person engineering team, working directly with the engineering lead on Mercury and Agent Karla, an AI-powered threat analyst that runs on the Mercury engine. You will ship new features and pay down tech debt in the same week. The team treats clean, maintainable code as a prerequisite, not a nice-to-have. If you want to build a product where what you ship reaches real users quickly, where you will shape how the engineering team works as it grows, and where the domain is genuinely interesting, keep reading. What You'll Do - Design, build, and ship backend services in Python: REST APIs, web services, data processing (60% of your time). - Build and maintain basic frontend features in React and TypeScript. - Write and maintain tests at every level: unit, integration, end-to-end (Playwright or similar). - Own CI/CD pipelines, code quality tooling, and static analysis. - Work with data: SQL queries, data modeling, domain modeling, and visualization. - Collaborate across teams, asking for help when stuck and proactively helping others. AI-First in Engineering We want AI to be part of QuoIntelligence’s engineering operating model. We expect engineers to use AI tools like Cursor by default across design, coding, debugging, testing, and documentation. This role is not about casually using AI for convenience. It is about using AI to materially increase speed, leanness, and impact. - Use AI to turn engineering leverage, shorten delivery cycles, and focus on high-value problems. - Strong judgment in using AI, understanding risks, and applying pragmatic safeguards. - Help re-engineer team workflows, build repeatable standards, and better tooling. - Coach teammates less familiar with agentic coding and drive AI adoption. What You'll Bring Must-haves: - AI-assisted development: actively use AI tools (e.g. Cursor) and evaluate their output critically. - Strong Python backend experience: designed and shipped production APIs, web services, and data processing systems. - Working familiarity in React and TypeScript: can build and maintain basic frontend features. - Solid testing discipline: unit, integration, and e2e testing are part of your work. - CI/CD and code quality tooling experience: set up or maintained pipelines. - Data proficiency: SQL, data modeling, and comfort with data analysis and visualization. - Clean code habits: produce readable, maintainable, and extendable code. Nice-to-haves: - Go or additional programming languages. - UX and design principles knowledge. Your First 90 Days - Month 1: By day 30, have a working mental model of Mercury's architecture. - Month 2: Own a significant feature end-to-end and start reshaping something. - Month 3: An engineering practice or system you built is now part of the team's workflow. What We Offer - Full ownership from day one. - Interesting domain: Unified Risk Intelligence solution with an AI-agentic product. - Remote with autonomy: small team, low bureaucracy, high trust. - Shape the engineering culture as the team grows. - AI-native workflow: Cursor is the standard tool. FAQ - How small is the engineering team? Four engineers (including the engineering lead). - Do I need cybersecurity experience? No, strong engineering fundamentals are what matter. - What is the tech stack? Python (backend), React/TypeScript (frontend), Playwright (e2e testing). The Process - Recruiter Interview - AI Fluency Interview - Team Interview - Live Coding - Offer
