Senior Software Engineer (Frontend) - Remote

Working at Tech Holding isn't just a job, it's an opportunity to be a part of something bigger. We are a full-service consulting firm that was founded on the premise of delivering predictable outcomes and high-quality solutions to our clients. Our founders and team members have industry experience and have held senior positions in a wide variety of companies – from emerging startups to large Fortune 50 firms – and we have taken our combined experiences and developed a unique approach that is supported by the principles of deep expertise, integrity, transparency, and dependability.
We’re looking for a Software Engineer in Mexico to help build an AI-powered risk intelligence platform. The platform helps enterprises detect and respond to emerging online threats. The team builds software with a spec-driven, AI-assisted workflow: engineers write clear specifications, plans, and acceptance criteria, then direct AI coding agents to implement, test, and refine the code. You’ll own features end to end and help the team improve how it ships with AI.
Translate product requirements into precise specs, technical plans, and task breakdowns that AI coding agents can carry out reliably
Use AI coding agents (e.g., Claude Code, Cursor, GitHub Copilot, or Kiro) to implement features, then review, test, and refine the code they produce
Own features end to end across backend services, APIs, and integrations, from spec through to production
Define acceptance criteria and automated tests up front so AI-generated code is checked against the spec
Maintain project context files, coding standards, and reusable prompts and templates that keep agent output consistent
Review AI-generated and human-written code for correctness, security, performance, and maintainability
4+ years of professional software engineering experience building and shipping production applications

• Hands-on experience using AI coding agents as a core part of your daily development workflow, not just autocomplete
• Practical experience with spec-driven development: writing specs, plans, or structured requirements that guide AI-generated implementation (e.g., GitHub Spec Kit, Kiro, or a similar approach of your own)
• Backend: Python, TypeScript/Node.js, or Go, plus REST APIs and SQL databases
• Full stack: the above plus React or a similar modern frontend framework

Strong testing discipline, including unit, integration, and test-first habits that validate AI-generated code
Experience deploying to a cloud platform (AWS, GCP, or Azure)
Excellent written and spoken English, especially strong written communication for specs and documentation
Experience setting up AI development tooling for a team, such as MCP servers, agent rules files, or shared prompt libraries
Experience with data-heavy or SaaS platforms, especially in security, threat intelligence, or trust and safety
Familiarity with Docker, Kubernetes, or infrastructure as code (e.g., Terraform)
