About V-Spot

V-Spot is a London-based cybersecurity research and technology institution. We conduct original security research, build defence technologies, and take on complex security engagements for government and enterprise clients across Europe. Our work spans zero-day research, blockchain security, and applied cryptography — we operate at the sharp end of the field.

The Engagement

We are looking for a Lead Security Analyst to join a specific, time-bound project: an independent security audit of did:webvh v1.0 — the decentralized identity protocol at the core of e-id infrastructure. 

The audit covers four areas:

• Cryptographic analysis of the did:webvh v1.0 specification (SCID derivation, entry hash chains, EdDSA/Ed25519, key lifecycle)
• Security assessment of the integration context (OID4VCI, OID4VP, SD-JWT VC, Trust Registry)
• Source code review of two open-source components: DID-Toolbox (Java) and DID-Resolver (Rust)

• STRIDE-based threat modelling and comparison against the existing threat model

   

What You Need

• 5+ years of hands-on experience in cryptographic security analysis and protocol auditing — not penetration testing of web apps, not cloud hardening. Protocol and cryptography work specifically.
• Real experience reading and auditing cryptographic specifications — finding logical flaws, not just implementation bugs
• Java code review for security — static analysis tools and manual review
• Rust code review for security — unsafe blocks, memory safety, concurrency issues
• Familiarity with decentralized identity standards: DID methods, Verifiable Credentials, W3C stack. Existing knowledge of did:web or did:webvh is a strong plus.
• Experience building STRIDE threat models on real engagements

• Ability to produce structured security reports with CVSS scoring for both technical and non-technical audiences

   

What Would Make You Stand Out

• Prior work on government digital identity systems or PKI infrastructure
• Published research in applied cryptography or protocol security
• Experience with Coordinated Vulnerability Disclosure (CVD) processes
• Knowledge of OID4VCI / OID4VP / SD-JWT ecosystem

Engagement Details

• Type: Contract (project-based)
• Location: Remote, with potential on-site sessions in Switzerland
• Language: English (German is a plus)
• Start: ASAP — timeline is fixed

To Apply

Tell us about a project where you audited a cryptographic protocol or specification — not a pentest, not a SAST scan. What did you analyze, what did you find, how did you report it? 

Your mission

Take full ownership of quality as a system, not a phase.
You will transform QA from a supporting function into a company-wide quality engineering discipline, driving process maturity, security awareness, and automation-first culture.

What you will actually do:

— Own and evolve QA strategy at the company level:
 define how quality is built, measured, and scaled across all projects

— Lead QA transformation initiatives:
 • move from manual-heavy QA to automation-first approach;
 • eliminate process chaos and introduce predictable, repeatable delivery models;
 • standardize QA practices across teamxs without killing flexibility.

— Embed security into QA processes (not as a checkbox):
 • define security testing standards;
 • integrate basic security checks into SDLC;
 • raise security awareness across engineering teams.

— Own non-functional quality:
 • performance & load testing strategy;
 • data integrity & database testing;
 • reliability for Live systems.

— Build a modern automation ecosystem:
 • define automation strategy across projects;
 • ensure frameworks are scalable, maintainable, and actually used;
 • drive high ROI automation (not “automation for the sake of automation”).

— Scale quality metrics that matter:
 • defect leakage;
 • automation efficiency;
 • team performance and delivery health.

— Build and lead a high-performance QA organization:
 • hire strong engineers, not “manual testers”;
 • grow people into T-shaped quality engineers;
 • mentor leads and shape future QA leaders.

— Partner with Engineering and DevOps to make quality a shared responsibility, not a QA bottleneck

What makes this role interesting:

— You are not “leading QA team” — you are shaping how the company builds software;
— You will work on processes that actually need fixing, not maintaining legacy bureaucracy;
— High level of ownership and decision-making power;
— Direct impact on engineering culture and delivery quality;
— Strong focus on growth and learning (courses, conferences, certifications);
 — Flexible work format (remote / office);
 — Paid vacations (23 business days) and sick leaves;
 — Full transparency on company performance.

We expect you to bring:

— Strong experience as Senior / Lead / Staff QA with real ownership of quality processes;
— Proven track record of building or transforming QA practices (not just supporting them);
— Deep expertise in:
 • test automation strategy and frameworks;
 • QA process design and scaling;
 • non-functional testing (performance, reliability, data).
— Solid understanding of security fundamentals in QA;
 (you don’t need to be a pentester, but you know where QA adds value in security)
— Experience working in multi-project / outsource environments is a big plus;
— Ability to operate on both levels:
 • strategic (define direction);
 • hands-on (get into tools, frameworks, problems when needed).
— Strong system thinking: you see QA as part of engineering ecosystem, not isolated function;
— Good technical background:
 • APIs, web, mobile;
 • logs, debugging, observability tools;
 • CI/CD understanding.
— English: Upper-Intermediate or higher.

Awesome if you have:

— Experience implementing OWASP-based practices or security testing workflows;
— Programming experience (Java / JS / Python) for building robust automation;
— Experience with quality metrics systems and data-driven decision making.

Application requirement: short intro video (required):

Please include a short self-introduction video (2–5 minutes). You can add the link directly to your resume or submit it through the hiring platform in any available way (YouTube, Loom, Google Drive, or similar).

• No need for a polished production, a simple smartphone recording is perfectly fine.
• This does not replace live conversations, it only helps us speed up the first screening and understand your communication style and motivation.
• In the video, please cover:
  • Who you are and 2–3 measurable outcomes you delivered in recent roles
  • Why you are applying for this role at Graphio.ai
  • Why you are leaving or have left your previous role
  • Your view on how a high-ownership startup team should operate (pace, ownership, communication, and work-life balance expectations)
• Applications without the video may not be reviewed.

Final note:

Graphio.ai is not a 9-to-5 corporate environment. We move fast, operate with high ownership, and expect proactive execution without micromanagement. Graphio.ai is a strong fit for people who actively seek challenges for personal growth - especially those who want to build their own company one day and see this as a place to learn how high-performing startups execute.

We are looking for a hands-on, commercially-minded Demand Generation Manager to own the full acquisition funnel — from paid media strategy and execution to lead nurturing, CRM hygiene, and pipeline reporting. You will work directly with the CMO, content, PR and SDR teams to build a scalable, repeatable engine that converts target accounts into qualified opportunities.

What You Will Own:

Paid Media Execution
•      Plan, launch, and optimize campaigns across LinkedIn Ads, Google Ads, Meta, and TikTok
•      Own targeting strategy for ICP segments: PSPs, banks, fintech startups, enterprise merchants
•      Manage ad budgets with a focus on pipeline efficiency, not just CPL
•      Write and iterate on ad copy briefs in collaboration with the content team and designer

Lead Generation & Nurturing
•      Design and manage lead capture flows: gated content, demo requests, webinar registrations, contact forms
•      Build and maintain HubSpot workflows for lead scoring, segmentation, and lifecycle stage transitions
•      Own email nurture sequences for MQL-to-SQL conversion in close partnership with the SDR team
•      Ensure data quality: country, business category, source attribution — across all inbound leads

Analytics & Reporting
•      Maintain GA4, GSC, and Google Ads dashboards; integrate with HubSpot for closed-loop attribution
•      Surface actionable insights — not just numbers — with recommended next steps

Cross-Functional Collaboration
•      Brief the content team on assets needed for campaigns (landing pages, case studies, comparison pages)
•      Align with the PR manager on earned media syndication opportunities that support paid amplification

What We're Looking For:

Must-Have Experience
•      2-3 years in B2B demand generation, growth marketing, or performance marketing
•      Proven track record running LinkedIn Ads in a B2B SaaS or fintech context — this is non-negotiable
•      Hands-on experience with Google Ads (Search, Display, YouTube) and Meta Ads
•      Working proficiency in HubSpot: workflows, lists, forms, deal pipeline, and basic reporting
•      Solid GA4 and GSC knowledge; comfortable setting up conversion tracking and interpreting attribution data
•      Experience generating pipeline for products with 3–12 month sales cycles

Strong Advantages
•      Experience marketing to PSPs, banks, payment processors, or fintech platforms
•      HubSpot certification or advanced HubSpot Marketing Hub experience
•      TikTok Ads experience for B2B audience building or retargeting
•      Familiarity with ABM methodologies and tools (e.g., LinkedIn Matched Audiences, intent data)

Who You Are
•      You think in pipelines, not campaigns — every tactic connects back to revenue impact
•      You're data-literate but not data-paralyzed; you can make a call with 70% confidence
•      You can write a sharp brief and give structured creative feedback
•      You're comfortable operating in a lean team where you own execution, not just strategy
•      You ask 'so what?' about every metric — and you have an answer

What We Offer:
 

• Fully remote work format with a flexible schedule;
• An engaging, large-scale project in the online payments sector;
• Competitive financial compensation;
• 20 working days of vacation and 10 paid sick leave.
