Spectrum - Cyber Security Agents
[Equity 30% adaptable] Seeking technical co-founder (20 hrs/week) for Spectrum – open-source AI red/blue team platform
We are William and Roland, and we are looking for a third co-founder to join Spectrum. William is technical (pentester by trade) and has built the current MVP. Roland is non-technical but handles pitches, business development, and user research. We recently had a third co-founder (Eman) leave due to personal schedule conflicts – no drama, fully amicable, and we have since clarified our vesting and commitment expectations.
Our repository: https://github.com/spectrum-redteam/spectrum
What Spectrum is:
Spectrum is an agentic cybersecurity platform that runs an autonomous Red Team agent (attacker) and a Blue Team agent (defender) simultaneously, powered by LLMs. A built‑in guardrail engine called LobsterTrap inspects every action in real time. The platform is written in Python, lightweight, and supports Google Gemini, HuggingFace, and AMD Cloud. It is designed for security researchers, penetration testers, and small teams who want to automate continuous adversarial testing.
Current state:
- Working MVP, installable via Homebrew, Docker, PyPI, and package managers.
- Can be configured with a local database and existing cybersecurity tools (Nmap, Metasploit, etc.).
- Clear product roadmap for the next 6 months: improved logging, more LLM providers, a simple web dashboard, and integration with Slack/Teams for alerts.
What we are looking for:
A technical co-founder who can commit about 20 hours per week. This is not a full‑time role yet, but we treat it as a serious partnership. You will have significant say in architecture, tooling, and feature prioritisation. Specifically, we need:
- Strong Python skills (async, type hints, packaging).
- Experience or strong interest in LLMs (prompt engineering, function calling, cost optimisation).
- Some familiarity with cybersecurity concepts (OWASP, common exploits, or at least willingness to learn).
- Self‑starter attitude – you will not be micromanaged.
Equity and terms:
- We are offering 30% equity (standard 4‑year vesting with 1‑year cliff) as a baseline, but we are adaptable. If you have different expectations (e.g., less equity but a future salary guarantee, or a different vesting schedule), we are open to discussion.
- This is equity‑only until we close a pre‑seed round or generate revenue (we plan to offer a hosted version).
- Roles: William can handle security logic, testing, and some Python development. You will co‑own the LLM agent framework, API design, and deployment automation. Roland will handle fundraising, marketing, and user outreach.
Small test task (to be completed after initial DM conversation, not required in first message):
If we move to a serious conversation, we will ask you to complete a small technical task to ensure we work well together. Example: Find an issue with our current project, fix it, and open a pull request.
Alternatively, write a short design doc (1‑2 pages) describing how you would add support for a new LLM provider (e.g., Anthropic Claude) including error handling and rate limiting. This is not free labour – it is a mutual filter. We will also share our internal roadmap and answer any questions you have about the codebase.
How to apply:
Send me a DM (William) with:
- A link to your GitHub or portfolio showing relevant Python/LLM work.
- A sentence or two about what excites you most about Spectrum or autonomous red teaming.
- Your rough weekly availability (e.g., “15‑20 hours, evenings and weekends”).
We are based in GMT +08:00 in Hong Kong. Remote is fine, but we expect 2‑3 synchronous calls per week (e.g., Discord). Serious inquiries only – please do not message if you cannot commit at least 15 hours per week for the next 6 months.
Let us build the future of AI‑driven cybersecurity together.
