About The Role

Join our team as a Principal Backend Engineer and serve as the Technical Lead for the Platform Integration team. In this high-impact role, you will shape the systems, architecture, and technical direction behind a product that helps security teams prioritize and fix weaknesses in their environment. You will be responsible for translating ambiguous product goals into concrete technical roadmaps, writing production code, mentoring other engineers, and influencing decisions across multiple projects and partner teams. This is an ideal opportunity for someone with deep expertise in software architecture and a passion for building scalable systems.

  • Contribuir al diseño y la implementación de sistemas escalables y arquitecturas técnicas para la integración de plataformas.
  • Colaborar con partes interesadas multifuncionales para traducir objetivos de producto y negocio ambiguos en estrategias técnicas concretas.
  • Mentorear y desarrollar ingenieros en el equipo, proporcionando retroalimentación reflexiva, coaching técnico y marcos que ayuden a otros a hacer su mejor trabajo.
  • This is an ideal opportunity for someone who has lived and breathed Integrations in a past life, and understands the power that a scalable API platform can allow for an entire class of power-users
  • You think in terms of platforms and systems, not just features, and you balance security, usability, and scalability in every decision
  • Deep expertise in software architecture, distributed or service-oriented systems, and the engineering tradeoffs involved in building durable, scalable products. We are at a critical inflection point and are investing heavily in building scalable systems for our continued growth
  • Experience working across multiple projects or workstreams at the same time while maintaining clarity on priorities, risks, and execution sequencing. Like most jobs, there will be competing priorities, you’ll help set priorities and communicate tradeoffs
  • Strong product judgment and the ability to translate business or customer needs into pragmatic technical decisions. If you only care about code, this may not be the right role for you
  • Strong written and verbal communication skills, including the ability to explain technical decisions and tradeoffs to non-technical stakeholders
  • A history of mentoring engineers, elevating team performance, and improving engineering craft through design feedback, code reviews, and technical guidance
  • Proven ability to work effectively with cross-functional partners including Product, Design, Security, peer engineering teams, and senior leadership
  • Comfort operating in ambiguity and making sound decisions with incomplete information
  • Strong technical leadership experience as a senior individual contributor or technical lead, with a track record of leading through influence rather than formal management authority. We are a small team that is growing quickly and you will play a crucial role in our success
  • 10+ years of professional software engineering experience
  • Bachelor’s degree in Computer Science, Computer Engineering, or a related field, or equivalent practical experience
  • Experience building backend services on a cloud platform (AWS, GCP, or Azure), and familiarity with Docker and containerized applications

  • Experience with PostgreSQL and performance tuning for large datasets
  • Experience with graph databases such as Neo4j or interest in learning them
  • Experience building or consuming GraphQL backends
  • Experience with ETL pipelines and data processing tools (e.g., Airflow-like frameworks, custom ETL jobs, or similar).
  • Experience with observability stacks (e.g., Datadog, Prometheus, Grafana) and instrumentation of services
  • Experience in cybersecurity, vulnerability management, security analytics, security data platforms, or adjacent domains
  • Required Tech Stack Experience
  • Backend development in one or more of: Go, Rust, Python, Java, or similar
  • Designing and operating APIs, services, and asynchronous or event-driven systems
  • Data modeling and persistence layers for product-grade backend systems
  • Technical design documents, architectural proposals, and engineering standards that can be adopted by other teams
  • Cloud-native application development and deployment patterns
  • Observability, reliability, and operational best practices for production services
  • Experience building products or platforms in vulnerability management, exposure management, security telemetry, or related cybersecurity domains
  • Familiarity with risk scoring, prioritization systems, or data-intensive backend workflows
  • Experience partnering closely with product managers to define and sequence an MVP without painting the team into a corner
  • Experience helping define technical standards or practices adopted beyond your immediate team
  • A track record of shaping technical direction more broadly across an organization, with influence extending beyond a single team or domain
