3What this role really is

This job involves testing the security of connected devices, looking at firmware, hardware and network protocols to find weaknesses.

4What you'd actually use

The tools this job runs on, and how well you'd need to know each one.

Ghidra (or IDA Pro) Intermediate

Reverse engineering firmware images to understand functionality, identify vulnerable code paths, and analyse proprietary protocols. You'll spend a lot of time here.

Wireshark Advanced

Capturing, filtering, and deeply analysing network traffic for IoT protocols (MQTT, CoAP, custom ones). You'll be building custom dissectors and complex filters.

nmap Intermediate

Network scanning to identify open ports, services, and device fingerprints on IoT devices and gateways. You'll be writing custom NSE scripts to find specific IoT services.

JTAG/UART Adapters (e.g., Bus Pirate, FTDI) Intermediate

Gaining low-level console access to devices, dumping firmware, and interacting with debug ports. This is your gateway to the hardware.

Metasploit / Burp Suite Community Edition Intermediate

Exploiting known vulnerabilities in device web interfaces and APIs, and intercepting/modifying HTTP/HTTPS traffic for web-based attacks.

Python (with Scapy, pwntools) Intermediate

Scripting custom network attacks, fuzzing proprietary protocols, automating exploit development, and parsing binary data. This is your go-to scripting language.

AWS IoT Core / Azure IoT Hub (Security Features) Intermediate

Auditing and assessing the security configurations (policies, certificates, device provisioning) of devices connected to cloud IoT platforms. You'll check if things are set up correctly.

5What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing in Where you are nowThe step above
Tool Selection for Assessment Uses tools specified by supervisor; seeks approval for new tool use. Selects appropriate tools (e.g., `Ghidra` vs `IDA Pro` for RE) for routine assessments; consults Senior Specialist for novel tools or significant investment. Defines and standardises toolchains for specific assessment types; approves new tool adoption for the team.
Vulnerability Prioritisation Prioritises based on CVSS score and supervisor's guidance; escalates any ambiguity. Prioritises vulnerabilities based on CVSS, business impact, and exploitability; consults Senior Specialist for high-risk or complex cases. Defines and refines vulnerability prioritisation framework for product lines; makes final call on critical vulnerability impact assessment.
Assessment Scope Changes Escalates all scope change requests to supervisor for review and approval. Proposes minor scope adjustments for efficiency (e.g., focusing on one module over another based on initial findings); seeks approval from Senior Specialist. Approves significant scope changes within their workstream; negotiates scope with Product Management and Engineering leads.
Remediation Recommendation Suggests standard remediation options; supervisor reviews all recommendations. Independently proposes detailed, practical remediation strategies for most vulnerabilities; consults Senior Specialist for complex architectural fixes. Architects and validates complex remediation strategies; influences product roadmap for security improvements.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Validated Findings per Assessment
The average number of confirmed, reproducible vulnerabilities (Severity Medium or higher) you identify and document per device security assessment.
Target · 8+ confirmed vulnerabilities (Medium or higher)

After assessing the 'Smart Home Hub v2', you delivered a report detailing 12 unique, reproducible Medium-to-Critical vulnerabilities, including a firmware downgrade attack and an insecure API endpoint. That's a good result.

Time-to-PoC (Proof-of-Concept)
The average time it takes you to develop a working Proof-of-Concept exploit for a critical or high-severity vulnerability after its initial discovery.
Target · PoC within 72 hours of discovery for Critical/High findings

You found a critical buffer overflow in the device's web server. Within 48 hours, you had a Python script demonstrating remote code execution, making it clear to engineering how serious it was.

Report Clarity & Actionability
The number of follow-up clarification requests from engineering teams regarding your assessment reports.
Target · < 3 requests for clarification per report

Your last report on the 'Connected Kettle' had zero questions from the firmware team because your steps-to-reproduce, evidence, and recommendations were so clear. That saves everyone time.

Assessment Throughput
The number of complete IoT device security assessments you independently conduct and deliver each quarter.
Target · 2-3 full device assessments per quarter (depending on complexity)

In Q2, you completed full security assessments for the 'Smart Doorbell', 'Garage Opener', and initiated the 'Pet Feeder' analysis. That's hitting your stride.

Technical Depth of Analysis
Your ability to go beyond surface-level vulnerabilities, diving deep into firmware, hardware, and protocol specifics to uncover complex or novel attack vectors.
  • Your reports consistently include detailed explanations of root causes (e.g., specific vulnerable code lines, hardware misconfigurations), not just symptoms. You're often the first to identify a non-obvious attack path, like a side-channel opportunity.
Collaboration with Engineering
How effectively you work with product and engineering teams to explain findings, discuss remediation strategies, and ensure security recommendations are practical and implemented.
  • Engineering teams actively seek your input early in their design process. You're seen as a helpful partner, not just a blocker. You can translate complex security jargon into language developers understand and act on.
Proactive Learning & Skill Development
Your initiative in staying current with the rapidly evolving IoT threat landscape, new attack techniques, and relevant security tools.
  • You regularly share interesting articles or new tools with the team. You're experimenting with new hardware hacking techniques in your spare time. You bring new ideas to team discussions about improving our security testing methodologies.
Documentation Quality
The clarity, accuracy, and completeness of your internal documentation, including test plans, tool configurations, and knowledge base entries.
  • Other team members can easily follow your test procedures or replicate your findings using your documentation. Your internal wiki contributions are well-organised and up-to-date, making it easier for everyone.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Solving Complex Puzzles

You thrive on the challenge of reverse-engineering undocumented protocols or finding a hidden debug port on a new device. Each assessment feels like a fresh puzzle to crack, and you genuinely enjoy the process of discovery.

Spending an afternoon with `Ghidra` and a logic analyser, slowly piecing together how a proprietary radio protocol works, and then finding a way to inject commands.

Tangible Impact on Security

You're motivated by knowing your work directly prevents real-world security incidents. Seeing a critical vulnerability you found get fixed before a product launch gives you a real buzz.

Discovering a serious flaw in an OTA update mechanism and then seeing the engineering team release a secure patch based on your findings, protecting millions of devices.

Continuous Learning & Mastery

You're driven by the opportunity to constantly learn new attack techniques, explore different hardware architectures, and master new tools. The idea of becoming an expert in a niche, challenging field excites you.

Successfully implementing a new side-channel attack technique you learned about online, even if it took several attempts and reading academic papers.

What frustrates people
  • The 'It's Behind a Firewall' Fallacy: Constantly battling the assumption from network teams that device-level security is unimportant because 'the network is secure'.
  • Vendor Indifference: Receiving a 'black box' device to secure with no source code, no schematics, and no support from the original manufacturer.
  • The BOM Cost Battle: Trying to justify an extra £0.10 per unit for a secure element chip to a management team obsessed with minimising the Bill of Materials (BOM) cost.
  • Proprietary Protocol Hell: Wasting weeks reverse-engineering a custom, undocumented protocol because a developer thought it was a 'secure' alternative to TLS.
  • The Physical Access Dismissal: Having a critical vulnerability downplayed because 'an attacker would need physical access', ignoring insider, supply chain, and 'evil maid' threats.
What this role does not give you
  • A predictable, routine 9-to-5 job – every day brings a new challenge, and some days are definitely longer than others.
  • A role where you only build things; you'll spend more time breaking and fixing than creating from scratch.
  • A role with immediate, high-level strategic influence – that comes later, after you've proven your technical chops.
  • A role where all the tools are perfectly documented and easy to use – you'll be wrestling with quirky hardware and command-line interfaces quite a bit.

8Who you work with

This role directly impacts the security posture and market reputation of our IoT product lines. Your work prevents critical vulnerabilities from reaching production, safeguarding customer data, ensuring device reliability, and avoiding costly post-launch remediation efforts or regulatory fines. Frankly, you're a crucial line of defence.

Inside the business
  • Product Engineering Teams (firmware, hardware, cloud)
  • Product Managers (for specific IoT devices)
  • Quality Assurance (QA) Teams
  • Legal & Compliance (for regulatory input)
Outside the business
  • Component Vendors (occasionally, for technical queries)
  • Security Researchers (when coordinating disclosures)

9What you need before you start

Not a wish list. The things you would be expected to already have.

  • At least 2 years of hands-on experience in security testing, penetration testing, or vulnerability research, ideally with some exposure to embedded systems or IoT.
  • A solid grasp of networking fundamentals (TCP/IP, common protocols) and operating system internals (Linux is a must, especially embedded Linux).
  • Proficiency in at least one scripting language for security tasks (Python is preferred, but strong C/C++ skills for reverse engineering are also highly valued).
  • Experience with basic reverse engineering tools like `Ghidra` or `IDA Free` and a willingness to dive deeper.
  • A proven track record of identifying and documenting security vulnerabilities in a clear, actionable manner.

10What to practise next

Where the job is going, and what to do about it starting this week.

Advanced Hardware Security Analysis

As software security improves, attackers are increasingly looking at hardware-level vulnerabilities. Understanding side-channel attacks, fault injection, and advanced physical tampering will become essential for truly robust device security.

Side-Channel Attacks (Power/EM) · Fault Injection (Glitching) · Secure Elements & Trusted Execution Environments · PCB Reverse Engineering

  • This quarter: Read up on `ChipWhisperer` tutorials and basic side-channel theory. Order a cheap development board to experiment with.
  • Next quarter: Attend a workshop or online course on hardware hacking or embedded security, focusing on physical attacks.
  • Month 6-12: Set up a basic `ChipWhisperer` lab (we can help with equipment) and attempt a simple side-channel attack on a known target.
  • Month 12-18: Start contributing to internal discussions on hardware security requirements for new product designs.

Quick win: Watch YouTube videos from Black Hat or DEF CON on hardware hacking. It's a great way to see what's possible and get inspired.

Scalable PKI & Device Identity Management

As our device fleet grows into the millions, managing individual device identities and certificates becomes a huge challenge. You'll need to understand how to design and implement PKI solutions that scale without becoming a security nightmare.

X.509 Certificate Lifecycle Management · Device Provisioning & Onboarding · Certificate Authority (CA) Operations · Hardware Security Modules (HSMs)

  • This quarter: Review our current device provisioning process and identify potential weaknesses in certificate handling.
  • Next quarter: Take an online course on PKI fundamentals or enterprise certificate management.
  • Month 6-12: Work with the cloud engineering team to audit existing `AWS IoT Core` or `Azure IoT Hub` certificate policies.
  • Month 12-18: Propose improvements to our device identity management strategy for a new product line.

Quick win: Familiarise yourself with `OpenSSL` commands for generating and inspecting certificates. It's a basic but powerful skill.

11Staying current once you are in

What people here do to keep up
  • Regularly participate in security conferences (like Black Hat, DEF CON, BSides) or local meetups to network and stay updated on the latest threats and techniques.
  • Contribute to open-source security projects or personal hardware hacking projects to continuously hone your skills and build a portfolio.
  • Subscribe to relevant security blogs, mailing lists (e.g., Full Disclosure, IoT security newsletters), and research papers.
  • Actively engage in Capture The Flag (CTF) competitions, especially those focused on embedded systems or hardware challenges.
  • Take online courses or workshops on advanced topics like reverse engineering, exploit development, or specific IoT protocols.

    Level 3 (Senior)

    • Lead multi-device assessments and complex threat modelling exercises.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, security analysis can be incredibly time-consuming. From sifting through mountains of firmware to manually correlating logs, there's a lot of grunt work. But what if you could offload some of that to AI? We're embracing cutting-edge AI tools to make our security specialists more efficient, allowing you to focus on the truly hard, creative hacking, not the tedious bits.

In this role, you'll be actively encouraged to use AI to augment your security analysis. We're not talking about replacing your brain; we're talking about giving you a powerful co-pilot that handles the repetitive, pattern-matching tasks, freeing you up for deep thinking and novel attack development. Think of it as having an extra pair of super-fast, tireless eyes on your side.

Automated Firmware Triage

Use AI-powered binary analysis tools to perform a first-pass scan on firmware images. It'll automatically identify cryptographic libraries, hardcoded keys, known vulnerable functions, and missing binary protections. This means less time manually digging through vast codebases for obvious flaws.

Protocol Anomaly Detection

Train a model on legitimate traffic captures from a proprietary IoT protocol. The AI can then monitor live traffic during testing and flag any anomalous packets or sequences that deviate from the norm, indicating potential fuzzing success or hidden functionality. No more endless scrolling through `Wireshark` captures.

Component Vulnerability Synthesis

Feed a Software Bill of Materials (SBOM) into a specialised LLM that cross-references each component (e.g., `dropbear` v2018.76, `busybox` v1.29) against CVE databases, exploit-db, and GitHub commit logs. It'll generate a prioritised list of potential vulnerabilities and publicly available exploits, saving you hours of manual research.

PoC Script & Report Generation

After identifying a vulnerability (say, a buffer overflow), use a code-generation AI to help draft a Python Proof-of-Concept exploit script using libraries like `Scapy` or `pwntools`. The same AI can then take your structured notes and generate the first draft of the technical vulnerability report, getting you to a final document much faster.
