Jobs at Djinni

PLVision is looking for an experienced Enterprise Network Architect with a deep understanding of how modern enterprise networks are designed, deployed, and operated. This role is critical in bridging real-world enterprise requirements with our open-source SONiC contributions, our internal SONiC Lite distribution, and other network operating systems we build for customers.

In this role, you will act as a subject-matter expert who defines enterprise-ready deployment models, verification methodologies, KPIs, and architectural blueprints that guide both our product roadmap and customer implementations. Your expertise will directly influence how our NOS offerings evolve, ensuring they are robust, intuitive, and aligned with real enterprise use cases, not limited to service provider environments.

This role is ideal for someone who has designed and operated complex enterprise networks and is motivated to shape the next generation of open networking solutions through hands-on architectural influence and strategic product impact.

Responsibilities

Architecture & Blueprint Definition
• Define reference architectures and deployment blueprints for SONiC, SONiC Lite, and customer-specific NOS distributions.
• Translate enterprise network requirements into system architecture specifications, configuration templates, and validated designs (VDs).
• Provide clear guidelines for L2/L3 fabrics, campus networks, DC leaf-spine, security zones, EVPN-VXLAN, QoS policies, and multisite designs.

Real-World Use Case Analysis
• Analyze typical enterprise challenges (brownfield migrations, multi-vendor networks, segmentation, QoS, monitoring gaps, high availability constraints).
• Ensure our NOS features solve actual enterprise operational pain points.
• Identify missing features, operational simplifications, or integrations needed by enterprise customers.

SONiC & SONiC Lite Product Shaping
• Work closely with engineering and product teams to drive enhancements to SONiC and SONiC Lite.
• Define feature requirements, acceptance criteria, success metrics, and expected behavior.
• Provide input to community-driven SONiC open-source development through clear and justified proposals.

Deployment Readiness, Testing, and KPIs
• Define verification plans, test cases, and rollout criteria for enterprise deployments.
• Establish network KPIs (latency, convergence, jitter, uptime, scaling limits) for each validated architecture.
• Work with QA teams to build automated test suites based on enterprise scenarios.

Documentation and Enablement
• Produce high-quality documentation:
• Deployment guides
• Best practice configurations
• Troubleshooting flows
• Operational handbooks
• Migration strategies
• Support creation of training materials and customer-facing onboarding content.

Customer Engagement
• Act as a technical authority during customer design discussions.
• Collect customer feedback and translate it into actionable product improvements.
• Assist in PoCs, architecture reviews, and complex deployments when needed.

Cross-Functional Collaboration
• Interface with Engineering, Product Management, QA, Support, and Sales Engineering.
• Influence long-term roadmap priorities based on enterprise expectations and market trends.
• Help shape broader company strategy around open networking adoption in enterprise environments.

Requirements

• 8+ years designing and operating enterprise networks at scale.
• Deep expertise in:
  • L2/L3 architectures, BGP, OSPF, EVPN-VXLAN
  • Campus + DC network design principles
  • High availability, redundancy, and failover strategies
  • QoS, ACLs, segmentation, multicast (optional but valuable)
• Strong understanding of NOS behavior (Cisco, Juniper, Arista, Cumulus, SONiC)
• Experience with automation (Ansible, Python, Nornir, etc.)
• Ability to write clear and concise documentation and architecture papers
• Familiarity with Linux-based NOSes and open networking ecosystems

Benefits

• Medical insurance
• Vacation and sick leave days
• Paid bank holidays (11 days in 2026)
• Relocation bonus
• Marriage and childbirth bonuses
• Referral bonus

• Set architecture patterns that other engineers follow.
• Partner directly with the founder on product and technical decisions.
• Stay hands-on: designing systems, writing code, reviewing pull requests, and shipping features.

This is an individual contributor role, not a people manager role, but your decisions will shape how other engineers build and ship.

Technical leadership

• Define and maintain architecture patterns across projects in our Node.js/TypeScript/React stack.
• Design scalable, well-documented APIs and backend systems used by multiple products.
• Establish shared libraries, tooling, and conventions so teams can move faster without reinventing the wheel.

• Integrate third-party APIs and services, including AI and large language model providers when they add real product value.
• Write clean, testable, maintainable code with a focus on long-term quality, not just short-term hacks.

• Create and maintain technical documentation that other engineers can rely on.

   

Product and ownership

• Work closely with the founder to translate business and product goals into technical strategies.
• Proactively propose improvements to products, architecture, and developer experience.
• Question requirements constructively and offer better solutions, not just point out problems.

• Take true ownership: surface risks early, suggest trade-offs, and follow through to shipped outcomes.

   

Team impact (without being a manager)

• Help other engineers make good architectural and implementation choices.
• Raise the bar on code quality, testing, and documentation through example and thoughtful review.

• Contribute to and refine the studio’s engineering practices, standards, and ownership culture.

   

What We Are Looking For:

Must-haves

• Senior-level experience (or above) building production systems in TypeScript and Node.js.
• Strong experience with modern frontend development using React.
• Proven track record of owning complex features or systems end to end: design, build, launch, iterate.
• Comfort operating in ambiguous environments: you can clarify requirements, propose approaches, and make decisions without needing rigid specifications.
• High ownership mindset: you think in terms of product and business impact, not just tasks completed.
• Strong communication skills: you document decisions, keep stakeholders updated, and communicate risks early.
• Experience designing APIs and backend architectures that serve multiple clients or products.

• Solid understanding of engineering fundamentals: data modeling, caching, performance, observability, testing.

   

AI and agents

• Real interest in AI and agents, with enough experience to integrate large language models or related services into products, for example calling an LLM API, designing prompts, or wiring tools.

• Excitement about using AI to build better products and workflows, even without a research background.

   

Nice-to-haves

• Experience acting as a de facto tech lead or staff-level individual contributor in a startup, studio, or multi-product environment.
• Experience with React Native or mobile development.
• Exposure to building internal platforms or shared component libraries for multiple teams or products.
• Experience with modern DevOps practices such as continuous integration and deployment, cloud infrastructure, and monitoring, sufficient to collaborate effectively with infrastructure-focused teammates.

• Prior work in early-stage companies or studios where you helped define engineering culture and practices.

   

Who You Are

• You are a builder who prefers shipping real things to only discussing them.
• You are energized by ambiguity and open problem spaces, not frustrated by them.
• You care about both the architecture and the user: you think about how your decisions affect the product and the business.
• You are comfortable being accountable: you make decisions, document them, and own the outcomes.
• You prefer lightweight process and clear ownership over heavy process and bureaucracy.

• You are not looking for a pure research role or a pure management role; you want to stay close to the code and the product.

   

How We Work

• Flat structure with direct communication between you, the founder, and the rest of the team.
• Multiple products in parallel, giving you exposure to a variety of problems and domains.
• Documentation and ownership: decisions get written down, and engineers are trusted to act on them.

• Remote-first: we work fully remotely and optimize for written communication and clear expectations.
