c3 is a deep tech company building a spatial intelligence data layer for the physical world. We operate at the intersection of computer vision, spatial computing, sensing technology, and cryptographic data integrity. Our work is technically ambitious, commercially significant, and largely without direct precedent.

We are pre-Series A, founder-led, and based between London and Kyiv. The founding team is small by design. We are not building a feature roadmap — we are building infrastructure that other products and markets will depend on. The engineering problems we are solving are genuinely hard and the data asset we are creating is genuinely novel.

This is not a role for someone who wants to manage a large team and attend planning ceremonies. It is a role for someone who wants to define the technical architecture of something that does not exist yet, hire the people who will build it, and be accountable for every significant technical decision made along the way.

1. The role:

You will be the first senior technical hire at c3. You will report directly to the founder and hold full ownership of the technical vision, architecture, and engineering team.

In the first six months you will:

• Audit and assess the existing codebase, infrastructure, and ML pipeline inherited from the initial build phase — make clear-eyed decisions about what to keep, what to rebuild, and what to discard
• Define the technical architecture across the full stack — mobile capture, cloud processing, ML inference pipeline, temporal data storage, cryptographic integrity, and API layer
• Make the first three to four engineering hires alongside the founder — senior ML/CV engineer, senior backend engineer, and iOS engineer — and own those hiring decisions fully
• Establish engineering practices, tooling, and standards from scratch — version control, CI/CD, code review, documentation — appropriate for a small high-output team, not a large enterprise
• Translate c3's core technical concepts into language that investors, partners, and regulators can engage with — you will be present in external conversations where the technical credibility of c3 is being assessed

From month six onwards you will:

• Own the technical roadmap and its execution across a growing team
• Lead the architecture of multi-source data capture, temporal analytics, change detection, and fraud prevention systems
• Build relationships with the Kyiv deep tech and academic community to support future hiring
• Contribute to IP strategy alongside the founder and legal counsel — c3 has active patent filings and the CTO will be central to future filings
• Define and own c3's data integrity model — immutability, cryptographic anchoring, audit trail — which underpins the commercial and legal value of the platform

2. What we are looking for:

Technical foundation

• Proven experience architecting and shipping production-grade data infrastructure systems — you have built things that handle real load, real failure, and real data integrity requirements
• Deep understanding of distributed systems design — event sourcing, immutable data architectures, append-only stores, or equivalent patterns where correctness is non-negotiable
• Strong working knowledge of ML systems in production — not research familiarity, but genuine experience integrating ML inference pipelines into backend infrastructure at scale
• Comfortable across the cloud infrastructure layer — AWS-native, infrastructure as code, CI/CD, monitoring, and cost management
• Experience with or strong understanding of cryptographic integrity patterns — blockchain anchoring, hash-based verification, or equivalent approaches to tamper-evident data systems

• Familiarity with spatial computing, computer vision, or sensing systems is a significant advantage — experience with point cloud processing, 3D data pipelines, or real-world capture systems is highly valued

   

Leadership and ownership

• You have led or co-led engineering teams in an early-stage environment where technical decisions compound fast and reversing them is expensive
• You hire well — you know what good looks like across ML, backend, and mobile engineering, and you can assess it quickly and accurately
• You write and speak clearly — architecture decisions, technical documentation, and investor conversations all require the same underlying clarity

• You are comfortable with ambiguity and honest about what you do not know — c3 is building in territory where the answers are not always established

   

Personal disposition

• You are genuinely motivated by hard technical problems in physical-world data — sensing, spatial reasoning, and real-world data capture interest you independently of this role
• You want to build something from the ground up and accept the instability and opportunity that comes with that
• You are based in Kyiv or willing to relocate — this is an office-based role and the Kyiv engineering community is central to how we hire and operate

• You take long-term ownership seriously — you are not looking for a twelve-month stint, you are looking for the thing you want to spend the next four or five years building

   

3. What we offer:

• Competitive salary reflecting genuine seniority — range discussed directly and transparently at first conversation
• Meaningful equity stake — you are joining as a founding team member, not a senior employee, and the package reflects that
• Full technical ownership — no existing CTO to report to, no inherited architecture you are obligated to preserve, no committees to persuade
• A Kyiv office environment that reflects the seriousness and culture of the work — small, focused, and built around the team
• Direct and ongoing involvement in IP strategy, investor conversations, and company direction — this is a seat at the table, not a delivery function
• The founder is based in Kyiv and operationally present — you will not be managing upwards across time zones or through intermediaries

About the role

We're building a performance marketing team from scratch, and email is a core channel for retention, reactivation, and lifecycle communication. This role owns all email communication across the company — transactional, marketing, and campaign-based — and works at the intersection of marketing and product to create a seamless user experience across web and mobile.

Responsibilities

• Full ownership of the email channel: strategy, execution, and performance across all communication types (transactional, broadcast, campaign, lifecycle flows).
• Design, build, and optimize automated flows and trigger-based sequences across the full user lifecycle — from onboarding and activation through engagement, re-engagement, and win-back.
• Develop segmentation strategies based on user behavior, product usage signals, and audience attributes to increase relevance and channel efficiency.
• Run systematic A/B tests on subject lines, content, timing, frequency, and flow logic. Formulate hypotheses, execute tests, and implement learnings.
• Work with users that enter the funnel (e.g., blog subscribers, quiz completions) but don't convert — build nurture sequences to move them toward action without aggressive frequency, respecting the sensitive nature of the product.
• Collaborate closely with the product team to ensure email communication is aligned with what's happening in the product (web + app), reflects the brand's tone of voice, and functions as part of a unified system rather than a siloed channel.
• Collaborate with the communications team, designers, and copywriters on email content. This role is the owner and final decision-maker on what gets sent, when, and to whom.
• Own email content creation and ideation — propose new campaigns, communication angles, and lifecycle touchpoints.
• Manage deliverability: domain health, sender reputation, spam rate monitoring, list hygiene.
• Build and maintain regular reporting on channel performance — open rates, CTR, conversion, unsubscribe rates, revenue attribution per flow.

For discussion: Participate in designing churn prevention flows triggered by product usage signals (e.g., no session booked in X days). Email is a secondary channel here — the logic and triggers will be defined jointly with the product team, but execution in email sits with this role.

Requirements

• 3+ years of experience in email marketing in a product company (SaaS, marketplace, or subscription-based product/edtech).
• Hands-on experience building automated flows and trigger-based campaigns in a marketing automation platform (experience with Customer.io is a strong plus).
• Strong understanding of user lifecycle stages and how email fits into the broader marketing and product funnel.
• Understanding of event-based triggers and audience parameters — ability to think in terms of "if user did X and didn't do Y within Z days, then…"
• Experience with segmentation, personalization, and A/B testing at scale.
• Solid grasp of email deliverability fundamentals (domain authentication, warm-up, list hygiene, spam triggers).
• Analytical mindset — comfortable working with data, interpreting metrics, and making decisions based on test results.
• Attention to detail, ownership mentality, and ability to work autonomously.

Nice to have

• Experience in health, wellness, or mental health products.
• Understanding of sensitive product communication — where intensity ≠ quality and user trust is paramount.
• Experience working with cross-functional teams (product, design, content).
• Familiarity with analytics tools (Mixpanel, GA4, or similar).
  
  What we offer:
• An opportunity to work on a health tech product that improves people’s mental well-being worldwide;
• Flexible schedule and full remote work - no strict location requirements;
• A team of passionate professionals who love what they do and foster an open, supportive atmosphere where every idea is heard and creativity is encouraged;
• Fully remote work with an option to visit our cozy office in Kyiv;
• Competitive compensation, based on your qualifications and experience;
• Paid time off 33 days per year (including public holidays);
• Paid sick leave 10 working days per year;
• Budget for learning and development;
• Paid mental health leave (5 working days per year).

About the role

We're building a performance marketing team, and this role is central to how we grow — owning conversion rates across all marketing touchpoints and the full user journey from first page view to first paid session. You'll work at the intersection of marketing, product, and engineering to generate, test, and scale ideas that move our core metrics: conversion rate, new clients, and CAC.

Responsibilities

• Own conversion performance across all marketing surfaces: main website, blog, landing pages, campaign funnels, and any new acquisition flows.
• Generate, prioritize, and execute CRO hypotheses — from ideation through briefing, prototyping, A/B testing, analysis, and implementation of winning variants.
• Design new funnels for paid channels (Meta, TikTok, and others as we scale), including concept, user flow, messaging framework, and success criteria. Coordinate execution with design, content, and engineering teams.
• Own the post-click experience for all paid traffic — ensure that what happens after a user clicks an ad is optimized for conversion, not just for traffic volume.
• Create and optimize landing pages for campaigns, audiences, and channels — working with designers and developers or using no-code/AI tools where appropriate.
• Monitor and analyze funnel performance at every stage (page view → authorization → first therapy created → first purchase). Identify drop-off points, diagnose root causes, and act on them.
• Run a continuous experimentation process: maintain a hypothesis backlog, manage test calendars, ensure statistical rigor, document results and learnings.
• Write clear briefs and technical specs for product and engineering teams. Communicate the goal, the hypothesis, the expected impact, and the success criteria for every initiative.
• Collaborate with the product team on the authorization-to-purchase flow. Currently owned by product — this role progressively takes over the marketing lens on this funnel, working jointly to improve it.
• Collaborate with the UA/paid channels manager on campaign-to-conversion alignment: ensuring ad creative messaging matches landing page experience, and that conversion signals are properly tracked.
• Participate in tracking and attribution setup alongside analytics — flag data gaps, validate conversion events, ensure the team can trust the numbers.
• Report regularly on conversion metrics, experiment results, and impact on new clients and CAC.

Requirements

• 3+ years in growth marketing, CRO, or a similar experimentation-driven role in a product company (marketplace, SaaS, subscription, or similar).
• Proven track record of improving conversion rates through systematic testing — not just ideas, but shipped experiments with measurable results.
• Strong understanding of user funnels, landing page best practices, and conversion psychology.
• Ability to write clear briefs, create wireframes or prototypes (even rough ones), and articulate what needs to be built and why.
• Hands-on experience with A/B testing tools (Google Optimize, VWO, Optimizely, or built-in product experimentation).
• Comfortable with analytics tools (GA4, Mixpanel, or similar) — able to pull data, interpret funnel reports, and make decisions based on evidence.
• Understanding of event-based tracking: how user events and parameters work, how they trigger flows, and what breaks when tracking is misconfigured.
• Strong cross-functional communication skills — this role lives between marketing, product and engineering daily.
• Structured thinking and ability to prioritize based on expected impact vs. effort.

Nice to have

• Experience with mental health, wellness, or other sensitive/high-trust products where aggressive conversion tactics don't work.
• Experience creating funnels for Meta Ads or other paid social channels specifically.
• Familiarity with no-code tools for landing pages
• Understanding of paid acquisition economics (CAC, LTV, ROAS) and how CRO improvements cascade into unit economics.
  
  What we offer:
• An opportunity to work on a health tech product that improves people’s mental well-being worldwide;

PaperLink (paperlink.online) is a document sharing platform with view analytics. You send a client a document and see who opened it, which pages they read, and how long they spent on each. Plus invoicing, financial tracking, and AI integration with Claude via MCP. No competitor has MCP-based AI integration.

The product is live. We need someone who can sell it and build the revenue foundation for what comes next.

What you'll do

• Bring first paying clients from your existing network or outreach
• Build and own the sales process from scratch
• Define ICP, messaging, and channels that work
• Lay the foundation for a future sales team

Who we're looking for

Someone who has done this before. You've built revenue at an early-stage B2B SaaS. You know how to close, and you know how to build the system around closing.

Ideally you have existing contacts in the target market: freelancers, consultants, law firms, agencies, or SMBs that regularly share documents with clients.

Part-time is fine. You likely work with several projects simultaneously. That's expected.

Compensation

Commission-based with equity participation tied to MRR milestones.

Commission-based on clients you bring. Equity participation as the product grows. Salary kicks in once MRR hits a defined threshold. All terms agreed upfront.

Payments: monthly, method by agreement.

Why this might interest you

The product exists and works. Competitors charge $45-150/month. We have a free plan and a real technical advantage.

The market is large. Every freelancer, lawyer, and consultant sends documents to clients.

Early stage means real influence. You define how revenue is built here, not inherit someone else's playbook.

What not to expect

Fixed salary from day one. If you need immediate stability, this isn't the right position.

A team to manage yet. That comes later. Right now it's you and the founder.

Format

Remote. Part-time. Flexible schedule. Any time zone.
