Staff Product Security Engineer - Offensive Testing
Finite State partners with product security teams, the guardians of our connected world, to create transparency for their connected devices and supply chains. Our platform handles connected devices and embedded systems across all industries, including those found in enterprises, healthcare, utilities, connected vehicles, manufacturing facilities, critical infrastructure, and government entities.
We are a fast-growing series-B company with a fully distributed workforce. Led by a team of seasoned experts, we are a mission-driven team passionate about arming our customers with the actionable insights, critical vulnerability data, and remediation guidance necessary to mitigate product risk and protect the connected attack surface. We are committed to a remote first culture.
Department: Services
Reports to: Head of PSC Engineering
Connected products run the world: vehicles, medical devices, industrial systems, and critical infrastructure—and securing them is one of the hardest engineering problems there is.
At Finite State, PSC Engineers are the technical owners of that problem for our customers: engineers who earn trust by building and shipping from the field.
You will work directly with the security and engineering teams of some of the world’s largest device manufacturers, analyzing their firmware, testing their products, assessing their risk, and building solutions on our platform that measurably harden what they ship.
You’ll do it with an outstanding and unique toolkit: our product security platform, the most advanced AI tooling available, and a team of genuinely world-class expert peers. This combination allows a single sharp engineer to deliver what once required an entire consulting team—and that is exactly the point.
You know your craft. You bring deep, hands-on product security expertise across embedded software and hardware security, firmware analysis, penetration testing, and threat and risk assessment. You’ve broken real devices and helped fix them.
You know the stack. You have a hands-on background evaluating the security posture of firmware, applications, networks, IoT, and embedded systems.
You improve the architecture. You have a proven track record of architecting features and hardening the security of complex networked or embedded environments, along with a strong command of the principles that drive secure product development and systemic design decisions.
You ship production code. You are experienced in building and deploying resilient, production-ready Linux and embedded systems.
You understand the adversary. You bring deep technical familiarity with reverse engineering techniques and the implementation of anti-tamper mechanisms.
You communicate at every altitude. You demonstrate exceptional professional clarity in writing and speech, with the ability to earn trust across technical and executive teams.
You build. You are proficient in one or more relevant modern programming languages, such as C/C++, Python, Go, Rust, TypeScript, or similar. You are comfortable working with APIs and automation and turning repetitive problems into scalable tools.
You are AI-native. You already use LLMs and agentic tooling as force multipliers in technical work, and you have the judgment to know where human ownership and validation are essential.
You are driven and self-directing. Give you a customer outcome and you find the path—no waiting to be told what to do. You hold yourself to a higher standard than anyone else sets for you.
You make others better. You share what you learn, draw on the expertise of your peers without ego, and build the kind of trust that makes customers ask for you by name.
You champion the team. You are committed to fostering a supportive, inclusive, and collaborative environment where every engineer and team member can excel.
You are certified for the offensive. You hold advanced credentials such as CISSP, CSSLP, OSCP, or OSWE, or have a proven history in exploit development and hands-on vulnerability research.
You navigate the regulatory landscape. You have practical familiarity with global standards and requirements, including the EU Cyber Resilience Act, RED EN 18031, FDA premarket cybersecurity requirements, or IEC 62443.
You speak hardware and firmware. You have deep technical knowledge of RTOS and embedded Linux internals, including JTAG, UART, SPI interfaces, and wireless communication protocols.
You secure complex systems. You have an expert understanding of the security architectures found in aerospace, medical, automotive, smart energy, smart city, home and commercial cyber-physical environments, and mission-critical embedded systems.
You master federal cyber policy. You bring fluency in modern U.S. government methodologies, including JSIG, ICD 503, NIST SP 800-160, and Cyber Survivability guidance.
You know the hardware logic. You have hands-on experience developing for programmable logic devices using industry-standard engineering tools.
You ship resilient code. You have a consistent record of building, testing, and deploying production-ready embedded and Linux systems from the field.
Because you’ll spend your time on the hard, interesting work: real devices, real adversaries, and real regulatory stakes.
You’ll have the leverage of a platform and AI stack that most security engineers do not yet have, while working on a team small enough that your contributions are visible and your standards help set the standard.
We depend on smart engineers who use cutting-edge technology and each other’s expertise to deliver something no one else can. If that sounds like a job description written for you, we should talk.
At Finite State, we're on a mission to secure the connected world. Our platform empowers product security teams to detect vulnerabilities, manage software supply chain risks, and ensure compliance across complex device ecosystems. From IoT to critical infrastructure, we provide unparalleled visibility into firmware and software components, helping organizations protect their products and customers.
We move with urgency and intent — we’re transparent, own outcomes, put customers first, speak up, and learn fast — turning evidence into action. CLARITY is how we move fast without breaking trust.
Bold Innovation – We push boundaries, explore new ideas, and take initiative to solve complex problems.
The Finite State platform brings visibility and control to the supply chains that create connected devices and embedded systems—all in a simple to use platform and at the scale manufacturers need to keep device production on time and on budget. After unpacking and analyzing every file, configuration, and setting in a firmware build, the platform generates a complete bill of materials for software components, identifies known and 0-day vulnerabilities, shows a contextual risk score, and provides actionable insights that product teams can use to secure their software
