Newfire is seeking a Senior Full-stack (Golang+React) Engineer

What's the Project?

We’re looking for a senior engineer to help modernize a surgical video platform operating in real clinical environments. The system combines Django/React/Go application layers with RTSP video pipelines, encoder integrations, on-prem infrastructure, and a planned migration toward AWS/EKS/S3. The work includes stabilizing production deployments, improving observability and failure detection, and shaping the future architecture of a platform that will later support AI-driven surgical analysis capabilities.

Your day-to-day activities:

Contribute to the stabilization and modernization of a legacy application
Troubleshoot and resolve issues across video ingestion pipelines, RTSP streams, encoder integrations, and backend services
Collaborate with engineering and product stakeholders to identify technical debt, architectural gaps, and reliability improvements
Design, implement, and optimize scalable backend APIs and services
Contribute to the migration of platform components from on-prem infrastructure to AWS-based environments
Participate in architecture and system design discussions related to scalability, reliability, and hybrid cloud/on-prem deployments
Investigate production incidents, perform root cause analysis, and implement long-term fixes
Collaborate with cross-functional teams during backlog refinement, technical planning, and delivery execution
Document technical decisions, architecture assumptions, and operational workflows as needed
Mentor engineers and contribute to engineering best practices where appropriate

You’re a perfect match if you have:

7+ years of software engineering experience
3+ years owning full stack systems
Senior-level Golang expertise (primary language); production experience with Go and React
Production experience building and maintaining distributed backend systems
Experience designing scalable APIs and backend services
Experience working with complex production systems and debugging live issues
Working knowledge of React (able to contribute to UI layer, not necessarily frontend specialist)
Experience working with cloud-based systems (AWS preferred)
Strong experience in system design and architectural decision-making
Ability to work with legacy systems and incrementally modernize them
Strong ownership mindset and comfort working in ambiguous technical environments
Experience in working with Agile Teams

Strong Plus:

Healthcare / clinical software experience
Experience with hardware-integrated systems
Experience with large binary/media data workflows
Experience with hybrid cloud + on-prem architectures
Exposure to AI/ML-enabled product ecosystems
Experience participating in architecture modernization initiatives

Please note that employment will be contingent upon providing documentation verifying your legal work authorization in the country of residence, in accordance with applicable law.
