Senior Staff Software Engineer - Cloud Platform

Lytx is building the future of its products on a scalable, cloud-first platform, fusing large-scale AWS infrastructure with the hardware that powers our in-vehicle gateways and smart cameras, plus the AI and fleet services layered on top. We're assembling a small, elite team of senior technical operators to own this platform end-to-end and define where Lytx goes next., * Architect, design, and build scalable, production-grade backend services running in AWS making critical technical decisions on system design, data modeling, and service boundaries with minimal oversight.

• Define and drive the technical direction of the cloud platform, including service architecture, infrastructure patterns, and operational standards that the team adopts.
• Develop and maintain services using Node.js and other backend technologies, with full ownership from design through deployment and production support.
• Leverage AI tools (e.g., Claude Code) as force multipliers in the development workflow.
• Design and implement infrastructure-as-code using AWS CDK, owning the full infrastructure lifecycle.
• Work with PostgreSQL at depth, including schema design, query performance optimization, and data architecture decisions.
• Build and maintain frontend applications using React & MUI and contribute to mobile applications built with React Native for Android and iOS.
• Develop software components across multiple languages: JavaScript/Node.js, Python, Rust, and C/C++, choosing the right tool for the problem.
• Set and uphold engineering standards for code quality, testing, reliability, and security, leading by example rather than by mandate.
• Evaluate emerging technologies, prototype solutions, and make build-vs-buy recommendations that shape the platform's technical roadmap.
• Operate as a full peer within a flat, high-trust team, participating in architectural discussions, code reviews, and production incident response with shared accountability.

We're looking for a Senior Staff Software Engineer with deep technical mastery and sharp architectural judgment to join as a core member. This is not a management role, and there's no hierarchy: every member operates with full autonomy - architecting solutions, writing production code, making high-stakes calls, and shipping at pace. You'll own problems end-to-end, from system design and backend services through infrastructure, frontend, and mobile, with direct accountability for production outcomes., * Bachelor's degree in Computer Science, Software Engineering, or equivalent depth of practical experience.

• 12+ years of software engineering experience building and operating cloud-based distributed systems at scale.
• Deep expertise with Node.js, React, and MUI in production environments.
• Proven mastery of distributed systems, microservices architecture, and cloud-native design patterns.
• Deep knowledge of AWS services and hands-on experience writing, testing, and maintaining AWS CDK scripts.
• Expertise in IP networking, including TCP/IP and related protocols.
• Demonstrated ability to operate across the full stack, backend, frontend, infrastructure, and deployment at a high level of proficiency in each.
• Track record of making sound architectural decisions independently and influencing technical direction beyond your immediate deliverables.
• Strong problem-solving skills with the ability to navigate ambiguity, make trade-offs, and deliver under time pressure.
• Effective communication skills, able to articulate architectural vision, defend technical trade-offs, and align with peers on approach.

Preferred Experience

• Large-scale, production cloud platforms serving high-volume, real-time workloads.
• IoT, device-integrated, or data-intensive systems.
• CI/CD pipelines, automated deployments, and infrastructure automation.
• Performance tuning, observability, and operational excellence in cloud environments.
• Prior experience in small, high-performance engineering teams with flat structures.

• Medical, dental and vision insurance
• Health Savings Account
• Flexible Spending Accounts
• Telehealth
• 401(k) and 401(k) match
• Life and AD&D insurance
• Short-Term and Long-Term Disability
• FTO or PTO
• Employee Well-Being program
• 11 paid holidays plus 1 inclusive holiday per year
• Volunteer Time Off
• Employee Referral program
• Education Reimbursement Program
• Employee Recognition and Appreciation program
• Additional perk and voluntary benefit programs

Salary is based on a number of factors including market location and may vary depending on job-related knowledge, skills, and experience. This position is also eligible for an incentive compensation plan. The expected hiring salary for this position is: $183,500.00 - $232,500.00
