Senior Staff Software Engineer, On-prem in United States at Jobgether

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Staff Software Engineer, On-prem based in the United States.

This is a highly technical architecture leadership role focused on designing and evolving large-scale, self-hosted security systems deployed in customer-controlled environments. You will own the end-to-end architecture of a mission-critical on-prem platform that delivers endpoint protection capabilities across enterprise, government, and regulated infrastructures. The role requires deep expertise in distributed systems, high availability, and resilient infrastructure design under constraints such as air-gapped networks and heterogeneous hardware environments. You will translate cloud-native and SaaS capabilities into robust on-prem solutions while ensuring scalability, performance, and operational reliability. Acting as a technical authority across multiple engineering teams, you will define architectural standards, review complex designs, and influence long-term engineering direction. This is a hands-on, high-impact role where your decisions directly shape how advanced security technologies operate in some of the most demanding environments.

• Own and evolve the end-to-end architecture of the self-hosted platform across multiple engineering teams, including backend services, data pipelines, and deployment topologies.
• Design and enforce standards for high availability, resilience, and fault tolerance, including clustering, replication, failover, and distributed consensus mechanisms.
• Define scalability and capacity planning strategies across diverse customer environments, including constrained, air-gapped, and heterogeneous infrastructure setups.
• Translate SaaS and cloud-native capabilities into robust on-prem architectures that can operate reliably in customer-controlled environments.
• Establish engineering standards, coding patterns, and architectural guidelines across teams to ensure consistency and long-term maintainability.
• Lead cross-team technical initiatives, influencing roadmap decisions and driving complex system-level designs to completion.
• Review and elevate architectural designs and implementations across senior engineering teams as a technical authority.
• Drive performance optimization, infrastructure efficiency, and operational excellence across deployed systems.

Requirements:

• 8+ years of software engineering experience with strong expertise in distributed systems and backend architecture.
• Proven experience building and scaling on-prem or self-hosted software deployed in customer-controlled environments.
• Strong proficiency in Go and/or Python, with experience working across systems such as PostgreSQL, MongoDB, Redis, Kafka, Docker, and Linux environments.
• Deep understanding of distributed systems concepts, including replication, clustering, consensus algorithms, and high availability design.
• Experience designing for scalability in constrained environments, including performance tuning, capacity planning, and hardware-aware architecture decisions.
• Demonstrated ability to lead complex, cross-team architectural initiatives and influence engineering roadmaps.
• Strong communication and mentorship skills, with the ability to guide senior engineers and align stakeholders on technical direction.
• Experience in security or endpoint protection systems is a strong plus.

Benefits:

• Competitive compensation package including base salary and equity (RSUs)
• Employee Stock Purchase Plan (ESPP)
• Flexible time off policy and paid holidays
• Comprehensive medical, dental, and vision insurance coverage
• 401(k) retirement plan with company match
