We're looking for someone who combines a creative strategist and a user acquisition lead — the owner of user acquisition who builds creatives that actually work and personally drives their scaling on Meta Ads. This isn't an execution role inside a ready-made structure. We're looking for someone ready to build the UA function from the ground up into a real system, make decisions on both the numbers and the content, influence business results, and grow together with the product.

Role context:

Product: a digital product for a business audience (details shared at the interview stage).

Geo: Tier-1 — US, Canada, and others.

Channels: Meta Ads (primary). 

Funnels: Web-to-Web and Web-to-App — the funnel is already built and working, no need to create it from scratch.

Spend: a significant monthly budget with an active scaling plan (numbers shared at the interview).

Role split — 60/40:

• 60% Creative: research on competitors, audiences, spy tools; generating ideas and hooks; briefing designers/AI production; analyzing why a creative worked or didn't.
• 40% User acquisition & analysis: launching campaigns, reading the numbers, deciding what to scale and what to kill.

Team philosophy: a small, effective team with no bloated headcount — no juniors, only self-sufficient, strong people.

Zero bureaucracy and zero micromanagement: decisions are made fast, we work for results, not process.

Creatives are produced through an AI pipeline (static/video generation, AI avatars) — you own and run it yourself. This person needs to work hands-on with tools and systems, not "manage vendors."

Compensation:

Base + % of spend with a KPI gate:

• Base salary range — $2,500–4,000 to start (final number negotiable, depending on level).
• Bonus: 2% of monthly spend up to $100k + 2.5% on everything above $100k — no cap: the more you scale, the more you earn.
• Bonus is paid when average monthly CPA is ≤ target cap and early cohort re-bill is at or above the norm (a quality-of-traffic safeguard).
• CPA exceeds cap by up to 15% → bonus rate ×0.5; more than 15% → no bonus for that month.
• Everything is calculated from two numbers (spend + CPA); you see the calculation base in the dashboard.
• Base salary review after 6 months based on results.

Equity: after 12 months of collaboration, based on results — the opportunity to receive a share/option in the product. This is a level of partnership that corporate structures simply don't offer.

Fully remote, no office ties!

A working funnel and product — not a "maybe it'll take off" startup lottery: the funnel is built, there are sales, the job is to systematize and scale.

AI-first approach: creative production runs on an AI pipeline, with budget for tools and freedom to experiment with the stack.

No bureaucracy: direct access to the founder, decisions made within a day, no approvals through five layers of management.

What you'll be responsible for:

• Researching competitors, audiences, and spy tools to generate ideas and hooks. 

• Briefing designers and AI production with high-quality creative requirements. 

• Implementing and developing AI tools in creative production (static/video generation, AI avatars). 

• Building and evolving a creative testing system. 

• Managing Meta Ads campaigns for Tier-1 markets (US, Canada, and others). 

• Forming hypotheses, analyzing test results, and scaling winning creative + targeting combinations. 

• Analyzing campaign performance: CPA, ROAS, cohort analytics, and key business metrics. 

• Scaling ad campaigns without losing efficiency. 

• Contributing to the development of the product's creative and marketing strategy.

What we're looking for:

• AT LEAST 2 years of experience as a User Acquisition Manager or Creative Strategist with a performance focus. 

• Experience working at product companies with a strong performance culture. 

• Hands-on experience managing budgets of $50,000+ per month on Meta Ads. 

• Experience working with Tier-1 markets. 

• Understanding of Web-to-Web and/or Web-to-App funnels. 

• A strong feel for creative: understanding hooks, trends, and why something resonates with an audience. 

• Experience building creative testing processes and making data-driven decisions. 

• Hands-on experience briefing designers and working with AI creative generation tools. 

• Strong analytical skills and systems thinking. 

• Self-driven, with ownership of results.

Nice to have:

• Experience with AppsFlyer, Adjust, AEM, CAPI. 

• Experience with spy tools (AdSpy, PiPiADS, Foreplay, etc.). 

• Experience scaling ad budgets 2–3x while maintaining target metrics.

• Experience with Google Ads or TikTok Ads.

What we offer:

• A hybrid role with a high level of autonomy and influence over the business — on both creative and numbers. 

• Base salary of $2,500–4,000 (depending on experience). 

• A bonus system tied to results and scaling. 

• The opportunity for a compensation review based on performance. 

• A path to equity in the product after a successful collaboration. 

• Fully remote work format. 

• A working product and an already-built sales funnel. 

• An AI-first approach and budget for modern tools. 

• Fast decision-making with no unnecessary bureaucracy.

If you're excited not just to run campaigns or just to make creatives, but to combine both and build a system that scales the product — I'd love to talk.

• Work on ingestion and processing of metadata (events, entities, timestamps, identifiers) used for workflow intelligence and reporting.
• Design and implement asynchronous and event-driven processes using RabbitMQ (queues, background jobs, retries, idempotency).
• Improve API reliability and performance: clear contracts, consistent error handling, pagination, and rate limiting.
• Work with databases:
  • MongoDB for operational and metadata storage,
  • ClickHouse for analytics, aggregations, and reporting workloads.
• Write and optimize queries, design schemas and indexes, participate in migrations, and help ensure data integrity and consistency.
• Implement authentication, authorization, and secure-by-default practices (permissions, tenant boundaries, safe handling of sensitive data).
• Write unit and integration tests; participate in code reviews and apply feedback quickly.
• Monitor and troubleshoot services in production: use logs, metrics, and tracing; contribute to root-cause fixes.
• Document backend services and APIs: how they work, how to run locally, and how to debug common issues.
• Contribute to engineering workflows: Git-based collaboration, containerized development (Docker), and CI/CD practices.
• Collaborate with Product, Frontend, and Engineering peers to deliver features in small, shippable increments in a remote environment.

• Startup experience or proven ability to move fast without heavy process.
• Experience with Kubernetes or cloud platforms (AWS, GCP, Azure).

What we offer:

• A practical growth role on real backend services used by customers, with clear feedback and mentorship from senior engineers.
• Work on meaningful product flows: metadata processing, workflow intelligence outputs, and reporting/alerts.
• A startup environment with low bureaucracy and fast iteration - you ship, learn, and improve quickly.
• Remote-friendly team with a simple setup and high trust.
• Competitive compensation (based on level) and growth opportunities as the team scales.

Company Operating Requirements:

At Graphio.ai we run a high-ownership, mission-driven team with clear operating rules. Please read these carefully before applying:

• LinkedIn profile is required (company policy). Employees are required to keep a current LinkedIn profile that shows their Graphio.ai position and is linked to the official Graphio.ai company page (company logo visible on the profile). Profile standards are provided during onboarding.
• Synchronized team vacations. The team takes coordinated time off four times per year to keep planning aligned and reduce context switching. Dates are announced in advance.
• Startup constraints. Vacation timing may be restricted during critical company periods. We plan time off as a team and communicate constraints early.
• Relocation readiness. Team members may reside in Ukraine, but must be prepared to relocate with their families to Europe or the United States if the company requests it and it becomes legally possible. Any relocation would be discussed in advance.
• Non-standard schedule. The role requires flexibility to collaborate across time zones. This may occasionally include early/late meetings depending on customer and team needs.

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.

Company overview:
 

Graphio connects to your existing systems through APIs to analyze events, activities, fields, and metadata. No content across documents or communication is analyzed.

Zero Integration: Works with your existing systems via APIs.

Zero Disruption: No changes to your current team workflows.

Privacy by Design: We analyze only fields, events, activities and metadata and don't analyze sensitive content across files and communication.

Rapid Deployment: Fully operational in under 48 hours.

SOC 2 Type 2, HIPAA compliant, and ISO 27001 (pending).

We’ve built and scaled before: the team behind Graphio.ai previously built upSWOT, a B2B platform adopted by hundreds of financial institutions, which was later acquired by Uptiq.  We’re applying those lessons in execution, delivery, and scale to Graphio.ai.

Supported by senior leaders from Experian, Mastercard, Lattice, BambooHR, Altrata, SAP, JackHenry, FIS, Pfizer, Workday, and more (graphio.ai/investors).

Position Overview:
 

We are looking for a Strong SecOps Engineer to own security operations and compliance for Graphio.ai — our compliance programs (SOC 2 Type 2, HIPAA, ISO 27001), the security architecture of a multi-tenant, AI-driven platform, and the audits, penetration tests, and customer security reviews that keep enterprise customers confident in how we handle their data.

This is a hands-on role for someone who treats security and compliance as an engineering discipline — rigorous and evidence-based — rather than a documentation exercise. You will build and run the processes that keep our security posture accurate, defensible, and consistent across every system, contract, and customer conversation.

You will work closely with Engineering on platform and infrastructure security, with Customer Success and Sales on enterprise security reviews, and with Legal on the security and data-handling terms of our contracts.

You will report directly to the CTO.

Key Responsibilities:
 

• Own and continuously operate our compliance programs (SOC 2 Type 2, HIPAA, ISO 27001): design controls correctly, keep evidence current, and make sure they hold up to independent scrutiny across the full period, not only at the point of testing.
• Design and run our penetration testing and vulnerability management program: define scope, prioritize findings by risk, and track remediation through to closure.
• Own the security architecture of a multi-tenant, AI-driven platform: data isolation between tenants and at the inference/model layer, including third-party infrastructure and GPU providers.
• Harden authentication, authorization, and network-layer defenses across our APIs and integrations, and keep that posture current as the product evolves.
• Keep our security and compliance documentation internally consistent — audits, contracts, architecture records, and public-facing claims should tell the same accurate story and stand up to scrutiny from customers and auditors.
• Lead technical engagement with enterprise customers during security reviews and due-diligence processes, acting as the internal authority on what we can credibly claim about our security posture.
• Manage risk from infrastructure and sub-processor vendors, including reviewing their security posture and attestations before we rely on them.
• Partner with Legal on the security and data-handling terms of customer and vendor contracts (including data processing agreements), so operational practice and written commitments stay aligned.

Preferred Qualifications:

• Substantial experience in security engineering, SecOps, or compliance engineering, including real ownership of at least one SOC 2, HIPAA, or ISO 27001 program from the inside.
• Practical experience running or managing a penetration testing and vulnerability management program, including remediation tracking and reporting.
• Solid understanding of multi-tenant SaaS security models and the tradeoffs between shared and dedicated infrastructure.
• Practical knowledge of cloud infrastructure security (Azure preferred; AWS or GCP acceptable), API security (authentication, authorization, rate limiting, WAF), and secrets and token lifecycle management.
• Familiarity with data processing agreements and similar compliance-related contract language, and comfort partnering with Legal on it.
• Experience handling enterprise customer security questionnaires and vendor due-diligence processes.
• A rigorous, evidence-first approach: comfortable being the internal authority on whether a security or compliance claim is actually accurate.

• Excellent written English: able to produce documentation clear and precise enough to satisfy external auditors and enterprise customers.

  
  Nice to have:

• Experience with AI/LLM inference security — isolating tenant context at the model layer, GPU-provider risk.
• Exposure to AI-specific attestation frameworks (e.g., ISO/IEC 42001) or willingness to build toward one.
• Experience building or scaling a compliance program in a startup environment.
• Experience with compliance automation tooling (e.g., Vanta, Drata, Secureframe, or similar).

What we offer:

• Full ownership of the security and compliance function — you build and run the program, not just execute someone else's checklist.
• Direct access to the CTO and engineering leadership, with a clear mandate to shape how security and compliance work at Graphio.ai.
• A product built for compliance-conscious enterprise customers, so this work has direct, visible business impact.
• Direct collaboration with Product, Machine Learning and AI specialists, and Software Engineers in a low-bureaucracy startup environment.
• Clear success metrics tied to audit outcomes, customer trust, and reduced security risk.
• Competitive compensation and room to grow into a company-wide security leadership role as we scale.

Company Operating Requirements:

At Graphio.ai we run a high-ownership, mission-driven team with clear operating rules. Please read these carefully before applying:

• LinkedIn profile is required (company policy). Employees are required to keep a current LinkedIn profile that shows their Graphio.ai position and is linked to the official Graphio.ai company page (company logo visible on the profile). Profile standards are provided during onboarding.
• Synchronized team vacations. The team takes coordinated time off four times per year to keep planning aligned and reduce context switching. Dates are announced in advance.
• Startup constraints. Vacation timing may be restricted during critical company periods. We plan time off as a team and communicate constraints early.
• Non-standard schedule. The role requires flexibility to collaborate across time zones. This may occasionally include early/late meetings depending on customer and team needs.
• US Eastern Time (ET) collaboration. This role requires regular overlap with US East Coast (ET) working hours. You must be comfortable running meetings, follow-ups, and execution in that time zone.
• Zero slow offboarding. We run lean and fast. When the fit isn’t there, we act quickly: employment may be ended within a day and access is removed immediately.

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.

Because we work with US-based stakeholders, you should be comfortable aligning part of your schedule with US Eastern Time (ET).
