About Us

E-commerce got real-time data infrastructure decades ago. Physical stores still have not. RADAR is changing that. RADAR is building the data infrastructure layer for the physical world, starting with retail. Our hardware-enabled SaaS platform uses proprietary overhead sensors, software, and AI-powered analytics to locate every product in a store, continuously, down to the fixture. We are deployed across 1,400+ stores with retailers including American Eagle Outfitters and Old Navy, processing tens of billions of real-world events every day, delivering 99%+ accuracy in complex, noisy environments - at fleet scale. RADAR is one of the best-funded companies in retail technology, backed by a recent Series B financing at a $1 billion valuation. Inventory accuracy is only the beginning. We believe RADAR can become foundational infrastructure for the physical economy, powering new AI-driven commerce experiences across retail and beyond. Join us if you want to work on a large, unsolved, technically challenging problem with an ambitious team building category-defining technology.

Our Values

• Mission-Driven: We're transforming retail with cutting-edge technology and building something that truly matters.
• Collaborative Team: We thrive on curiosity, shared goals, and solving complex problems together.
• High Impact: You'll make meaningful contributions from day one and help shape the future of our product and company.
• Clear Communication: We value honesty, humility, and respectful dialogue—everyone's voice matters.
• Balanced Lives: We work hard, but not at the expense of well-being. We respect time, boundaries, and life outside of work.
• Diverse Perspectives: We believe better ideas come from diverse backgrounds, experiences, and viewpoints.
• Empathy-Driven Design: We build with deep respect for our end users, listening closely to their feedback and needs.

About The Job

Radar is hiring a Systems Engineer who will take end-to-end ownership of system-level inventory features. Radar's system consists of custom RFID sensors with complex hardware, firmware, software and cloud integration. The System Engineer will own cross-functional features to ensure that performance and quality standards are achieved across all hardware and software subsystems and components in the system. You will oversee feature implementation of the integrated system through testing, debug and customer release, and collaborate across all engineering teams including hardware, embedded software and analytics. Ultimately, you will be leading the problem solving process, writing requirements, coordinating cross-functionally and analyzing system-level data to ensure all customer-facing features perform as expected.

Responsibilities:

• End-to-end Ownership: you will be the go-to person for your assigned feature. You will understand how each component of the system contributes to the functionality and performance of the feature, lead cross functional work groups, validate and debug issues, analyze test data to draw practical conclusions, and report status to leadership.
• Requirements: Write detailed, testable feature requirements with well-defined acceptance criteria for testing to ensure the implemented feature meets both internal and customer expectations. Decompose requirements to subsystem levels to inform required component performance.
• Data Analysis: Create and run your own analyses in Python/SQL as needed; synthesize findings from other team members. Dig into production data from stores to understand how features are performing in the field
• Timeline and Plan: Create and execute a plan for feature problem resolution and release. Communicate the plan with scope and timing to engineering and product leadership

About You

Required:

• You have a B.S. in Engineering or any equivalent technical discipline
• 3-5 years of experience working on integrated hardware, firmware and software sensors or products
• You have strong problem solving and communication skills
• You are proficient with Python
• You have strong leadership skills - you can translate between engineering disciplines and align stakeholders with different technical backgrounds or opinions
• You enjoy both diving into the details of a problem and also understanding the high level context around it
• You have experience writing system requirements, test plans, or feature specs that guide cross-functional engineering team implementation
• You are comfortable operating autonomously in ambiguity
• You have experience working across hardware and software disciplines
• You maintain an entrepreneurial spirit with a general attitude of "figure it out" when faced with a difficult problem of any type

Preferred:

• Experience working on RF systems
• Experience writing and automating test scripts for integrated hardware/software products

What You'll Do

In your first 30 days, you will:

• Learn Radar's mission, technology stack and core values.
• Complete onboarding and security compliance training.
• Familiarize yourself with Radar's system architecture, especially as it relates to your key feature(s)

In your first 60 days, you will:

• Dive into the current status of the feature to understand where the gaps or potential failure modes exist.
• Create a plan mapping out all required work and identifying key blockers for success. Develop relationships with key contributors and stakeholders for the scoped work
• Familiarize yourself with Radar's tools and testing capabilities - understand existing test setups and data infrastructure, with capabilities to analyze relevant data as needed.

In your first 90 days, you will:

• Understand the full scope of your assigned feature, with a plan for maintaining high quality through the upcoming release cycle
• Lead a standing weekly cross-functional feature meeting where feature design, implementation, and test are planned and reviewed
• Create a set of requirements to outline the key performance required for your feature. Complete hands-on data analysis to characterize the performance of your feature and compare against the stated requirements.

At RADAR, your base pay is one part of your total compensation package. The expected base salary range for this position is $120,000 - $160,000 . Individual pay is determined by work location and additional factors, including job-related skills, experience and relevant education or training. You will also be eligible to receive other benefits including: equity, comprehensive medical and dental coverage, life and disability benefits, 401k plan, flexible time off, and paid parental leave. The pay range listed for this position is a good faith and reasonable estimate of the range of possible base compensation at the time of posting.

Research has shown that women & underrepresented minorities are more likely to read lists of requirements and consider themselves unqualified if they don't meet every single one. This list represents what we're ideally looking for, but everyone has unique strengths & weaknesses, and we hire for strength & potential, not lack of weakness.

Use of artificial intelligence or a LLM such as ChatGPT during the interview process will be grounds for rejection of your application process.
