Senior Security Engineer Cryptography
for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). They say do NOT repeat the job title as a heading. They want sections only when posting has real specific content. So we need to map content to appropriate headings.
We have:
- About Trail Of Bits: company overview. Could be "About the role"? Actually "About the role" is typical heading for role description. But we have a separate "The Role" section describing role. Could use About the role
for that. Or we could use "About Trail Of Bits" as company description maybe not needed. The rules list examples but not strict; we can use headings that match content. Probably better to use headings: About the role, Responsibilities (What You'll Do), Requirements, Nice to Have (maybe Qualifications?), Benefits, Pay (Compensation). Also maybe "How This Role Fits the Team" and "What Success Looks Like" could be part of Responsibilities or separate? Could combine but better to keep as separate sections if they have substantive content. The rules: Prefer a few substantive sections over many thin ones. But we can still include if they are substantive. However "How This Role Fits the Team" and "What Success Looks Like" are somewhat generic but still specific. Might combine into "Responsibilities" or "Expectations". But we have "What You'll Do" which is responsibilities. The other two are more about expectations and success metrics. Could be included under "Responsibilities" as well. But to follow instruction: include a section ONLY when posting has real, specific content for it. Those sections have specific content, so we could keep them.
But we need to decide headings: Use for section headings. Use - for any list of duties/requirements/benefits, and
for prose.
We must not include boilerplate like EEO, E-Verify, etc. Also remove duplicated lines, navigation, cookie, legal, scam-warning, application instructions. Also remove "Learn More Here." etc.
We need to preserve all substantive information.
Let's extract content:
Company description: "United States | Remote | Full time About Trail Of Bits Founded in 2012 by 3 expert hackers with no investment capital, Trail of Bits is the premier place for security experts to boldly advance security and address technology's newest and most challenging risks. It has helped secure some of the world's most targeted organizations and devices. Our combination of novel research with practical solutions reduces the security risks that our clients face from emerging technologies. Our work helps drive the security industry and the public understanding of the technology underlying our world. Cybersecurity preparedness is a moving target. Companies like ours are the tip of the spear in the fight against attackers. Our research-based and custom-engineering approach ensures that our client's capabilities are at the forefront of what's available. For companies and technologies that live and die by their security, a proactive, tailored approach is required to keep one step ahead of attackers. Democratizing security information is essential. As part of our business, we provide ongoing informational support through blogs, whitepapers, newsletters, meetups, and open-source tools. The more the community understands security, the more they'll understand why a company like ours is so unique and valuable."
That's substantive; we could put under
About Trail of Bits
maybe. But the rules examples didn't list "About the company". However they said use headings like About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. They didn't forbid other headings; they just gave examples. Probably okay to use About Trail of Bits.
But maybe better to incorporate that into a brief intro paragraph before sections, not as a heading. The instruction: "Do NOT repeat the job title as a heading (the page already shows it) and do NOT put Job ID / requisition numbers as headings — fold minor metadata into a short or drop it." It doesn't forbid other headings. So we can have a heading for company overview.
Now sections:
- The Role: description of role: "We're hiring a Senior Security Engineer for the Cryptography team to review and strengthen high-assurance software and cryptographic systems used across technology, finance, defense, and blockchain. You will evaluate whether cryptographic designs and implementations deliver the security properties they claim, find subtle failures where theory meets code, and help clients make sound decisions about risk and remediation. On a typical engagement, you might review a new protocol, analyze an implementation of a standard primitive, test assumptions in a post-quantum construction, or build tooling that makes future assessments faster and more rigorous. The work spans code review, cryptanalysis, threat modeling, technical writing, and direct collaboration with client engineers. This is a senior individual-contributor role. You will independently lead substantial parts of engagements, exercise judgment when the problem is ambiguous, communicate clearly with clients and peers, and help raise the technical bar for the cryptography team. You will also have room to contribute to open-source tools, public research, and new service offerings."
That's substantive; could be under

or The Role
. Use About the role as per examples.
- What You'll Do: list of duties. We'll make - items.
List items:
1. Lead cryptographic assessments. Review protocols, libraries, and application code; identify design and implementation weaknesses; validate exploitability; and recommend practical fixes
2. Analyze advanced constructions. Work across standardized symmetric and asymmetric cryptography, post-quantum schemes, zero-knowledge proof systems, and multi-party computation protocols, learning unfamiliar designs when an engagement demands it
3. Build useful tooling. Create or extend tools, test harnesses, and proofs of concept that improve cryptanalysis, implementation review, and repeatability across engagements
4. Own clear client delivery. Plan your work, surface risk early, lead technical discussions, and produce precise reports that explain both the finding and the engineering path forward
5. Shape the practice. Contribute to scoping and methodology, mentor other engineers, identify promising research or tooling opportunities, and help turn repeated client needs into stronger services
6. Share what you learn. Contribute to open-source projects and, when appropriate, publish technical work or present it to the security and cryptography communities
- How This Role Fits the Team: paragraph.
- What Success Looks Like: bullet points? It's a list of statements. Could be
