Backend Engineer - Node.js / TypeScript
Location: Remote| Full-Time
Underdog.io is a modern recruitment platform. Our hiring partner is pioneering a platform backed by $14M from top-tier investors, enabling enterprises to deploy authenticated AI agents for mission-critical workflows.
Our technology solves a fundamental challenge: securely accessing and transforming data trapped behind complex authentication barriers. We’ve automated weeks-long manual processes into minutes for industry leaders. Join our growing team to build the infrastructure that makes every business system AI-accessible.
Your Mission
Architect core systems that allow AI agents to securely navigate authenticated environments—from dynamic web interfaces to legacy systems—transforming unstructured data into actionable intelligence at scale.
Key Responsibilities
- Build Resilient AI Agents: Develop systems that automate complex logins (including MFA), extract unstructured data, and handle dynamic web interfaces without APIs.
- Engineer Secure Foundations: Create authentication workflows for diverse platforms and scalable APIs for enterprise-grade solutions.
- Design Data Infrastructure: Implement GCP-based data pipelines, optimize PostgreSQL performance, and ensure integrity for millions of records.
- Ship End-to-End Systems: Develop third-party integrations, testing suites, and observability tools with a focus on reliability.
- Collaborate Strategically: Work with senior engineers on system architecture and product teams to solve real customer challenges.
Tech Stack Deep Dive
- Core: TypeScript, Node.js, PostgreSQL
- Infra: GCP, Docker, GitHub Actions (CI/CD)
- Automation: Custom web agents, Puppeteer/Playwright (experience a plus)
Who You Are
- 3+ years backend engineering experience shipping production systems.
Technical Mastery:
- Proficient in modern backends (Node.js/TypeScript preferred)
- Experience with REST APIs, cloud platforms (GCP/AWS/Azure), and databases
- Familiarity with containerization (Docker) and CI/CD pipelines
Cultural Fit:
- Autonomy: Own outcomes end-to-end in ambiguous environments
- Craftsmanship: Balance best practices with pragmatic delivery
- Curiosity: Continuously explore authentication, security, and AI/automation
- Communication: Document decisions and align cross-functional teams
Nice-to-Haves
- Data engineering/ETL pipeline experience
- Knowledge of OAuth, SAML, or security protocols
- Startup experience or open-source contributions
- Monitoring tools (Prometheus, Grafana, etc.)
Why Join
- Impact Critical Infrastructure: Your code enables AI to access 90% of enterprise data currently locked behind logins.
- Founder-Level Equity: Significant ownership in a well-funded startup.
- Elite Team: Learn from former founders and early engineers who scaled 0→1 products.
