What the job involves
- Jus Mundi is looking for a Staff Engineer to play a critical role in shaping and sustaining a resilient, secure, and scalable platform that acts as a force multiplier for our entire engineering organization
- Engineering Product Design team North Star is “Zero-friction delivery: We deliver business value at speed and securely by mastering simple, standardized engineering practices.”
- You will be the technical guardian of this mission, doing whatever it takes, from hands-on implementation to cross-team orchestration to make it happen, grounding every technical decision in product impact and a deep understanding of our business context (users, workflows, and value drivers)
- This role balances strategic technical leadership with hands-on engineering work
- You’ll roll up your sleeves for critical stack upgrades (PHP, Symfony, third party libraries, etc.) as much as you’ll architect large-scale system transitions
- This is a senior individual contributor role with broad influence, designed for an engineer who drives impact through architecture, standards, mentorship, and product-oriented technical leadership rather than people management
- You will work across multiple product and platform teams within Jus Mundi’s Engineering organization, collaborating closely with Engineering, Product, AI, and Security stakeholders from different squads to define shared foundations and enable teams to move faster and safer
- Our engineering culture values high ownership, pragmatism, collaboration, and technical excellence
- Drive architectural decisions and technical strategy across multiple teams and domains, with a strong focus on product outcomes and user impact
- Design and evolve fault-tolerant, scalable distributed systems
- Guide teams toward sound architectural decisions and coordinate initiatives across multiple squads
- Partner with Product and Engineering leaders to balance technical trade-offs with business value
- Hands-On Technical Work
- Tackle essential work such as stack upgrades (PHP, Symfony) and technical migrations
- Write production code across different domains and rapidly context-switch between technical subjects
- Jump into crisis situations and drive resolution (e.g., critical infrastructure incidents)
- Lead by example in code quality, testing strategies, security by design, and deployment best practices
- Platform Excellence & Engineering Framework
- Lead the implementation of our new engineering framework (priority #1)
- Define and enforce engineering standards related to reliability, security, testing, and deployment
- Lead the transition toward fully automated, self-healing, and immutable infrastructure
- Drive platform-wide initiatives that improve developer productivity, system reliability, and end-user experience
