Tech Lead Software Engineer - OpenGRC

🌀 The Company

Filigran, founded in October 2022, stands out in the cybertech ecosystem for its commitment to revolutionizing cyber threat management with a proactive approach. Its mission is to develop innovative open-source solutions designed to anticipate cyber threats, identify security gaps, and strengthen organizational security posture. Filigran solutions are now trusted by over 6,000 public and private organizations worldwide.

We're looking for a Staff / Lead Software Engineer to be the technical founding pillar of our new OpenGRC team. You'll work closely with the Engineering Manager and a small, agile squad to define the technical architecture and build the MVP. You will define the technical strategy, system architecture, and engineering standards for a solution that turns abstract threat data into verified, quantified action plans.

You will balance hands‑on coding of the most complex components with high‑level architectural decision‑making, setting the trajectory for a scalable Open Source product.

• Technical Vision & Architecture:
  Own the technical roadmap and system design. You will architect a clean, scalable Single Page App (SPA) and event‑driven backend (Node.js/Type Script) capable of deployment as both SaaS and On‑Premise. You will anticipate scaling challenges related to heavy data ingestion and cross‑platform integrations.
• Core Engine Ownership:
  Architect and drive the implementation of the complex engines that differentiate OpenGRC:
  • Correlation Engine:
    Designing logic to link CTI feeds (STIX objects) to internal Assets and Controls.
  • Quantification Engine:
    Creating the mathematical models and algorithms to calculate financial risk dynamically based on changing threat landscapes.
• Engineering Standards & Mentorship:
  As a Lead, you will set the bar for code quality, testing patterns, and documentation. You will mentor future hires, conduct code reviews, and foster a culture of technical excellence and psychological safety.
• Strategic Product Engineering:
  Partner with Product Management to translate business goals into technical reality. You will play a key role in defining domain models for "Threat Contexts" and "Risk Scenarios," ensuring the technology can support future "What‑If" simulations.
• Ecosystem Integration:
  Lead the technical alignment with the wider ecosystem (OpenCTI, OpenAEV). You will ensure OpenGRC integrates seamlessly with these platforms, requiring deep collaboration with Principal Engineers across the organization.
• Open Source Leadership:
  Act as the technical face of OpenGRC in the open‑source community. You will engage with contributors on Git Hub/Slack, guide community architecture decisions, and manage external contributions.

• Direct report:
  You will report to the Engineering Manager of OpenGRC.
• Team:
  You will lead the technical execution of the initial squad, with plans for the team to grow rapidly.
• Collaboration:
  
  You will operate as a peer to the VP of Tech, CTO, and Principal Engineers, aligning on organization‑wide technical standards and integration strategies.

• Experience:
  
  10+ years of experience in Software Engineering, with significant proven experience in mentoring software teams and leading technical topics.
• Staff/Tech Lead
  
  Experience:
  
  You have a proven track record of designing and delivering complex systems from scratch. You have experience not just contributing to codebases, but owning the architecture and technical health of a product.
• System Design Mastery:
  You excel at data modeling (Entities, Relationships) and designing distributed systems. You can articulate the trade‑offs between different architectural patterns (SQL vs No
  
  SQL, Event‑driven vs REST, etc.) and make decisions that balance speed of delivery with long‑term maintainability.
• Full Stack Expertise:
  Deep proficiency in React, Type Script, and Node.js. You can bridge a distributed SQL backend handling massive scale with a high‑performance, intuitive React UI. You understand the nuances of end‑to‑end type safety and performance optimization.
• Product‑Minded Leader:
  You understand the "Why" behind the code. You are…
