About c3

c3 is building the spatial intelligence data layer for the global rental market. We are preparing for a commercial pilot in the UK and US.

The role

You will be one of the first engineering hire into the product team, reporting to our existing backend consultant and working directly with the founder. Your immediate focus is preparing the App Clip and user-facing dashboard for pilot deployment - refining the frontend to the specific workflow needs of each pilot client, then running a tight feedback loop with those clients to improve the scan experience and fix issues in real time.

Longer term, you will own the data collection user experience end-to-end, building the scan pipeline into a dataset that is clean, structured, and ready for the ML/CV engineer who joins in the next phase.

What you will do

• Refine and harden the existing iOS App Clip (SLAM/LiDAR pipeline, point cloud capture, GLB output) for deployment
• Work directly with pilot users
• Run a structured feedback loop: capture issues, prioritise fixes, deploy rapidly
• Ensure scan outputs are consistent, complete, and correctly structured for downstream ML use
• Build the labelling and QA tooling the ML/CV engineer will need to begin training the comparison model

• Maintain and improve the agent dashboard as pilot requirements evolve

   

What we are looking for

• Strong iOS development (Swift, SwiftUI) with production App Clip or App experience
• Hands-on experience with ARKit
• SLAM/LiDAR frameworks - you have shipped something that uses the iPhone's spatial sensing hardware
• Comfortable across the full stack - backend integrations, data pipelines, cloud infrastructure - not just the frontend
• Experience collecting and structuring data for ML pipelines is a strong advantage
• Able to work with ambiguity, move fast, and communicate clearly with non-technical clients
• Fluent English - you will be on calls with UK and US users and team regularly

• Based in Kyiv preferred; hybrid or remote considered for the right candidate

   

What we offer

• Direct collaboration with the founder and a small, focused team building something technically novel
• Competitive salary benchmarked to Kyiv senior engineer market rates
• The opportunity to own a product that is already built, already works, and is going into real commercial use immediately

About the Role

We're building one of the fastest-growing telehealth platforms in the weight loss space, and our marketing team is genuinely strong — creative, in-house, and moving fast. The one gap we have is email, and we're done patching it with an agency. We need someone who owns this channel completely, top to bottom, and treats it like a core growth lever — not a checkbox.

This is a senior individual contributor role. You'll be the entire email function. That means strategy, execution, QA, segmentation, performance, and iteration — all yours.

What You'll Own

• Full lifecycle email program: acquisition, onboarding, retention, winback, transactional
• Campaign strategy and calendar across patient and prospect audiences
• Copywriting and creative direction (working with our in-house design team and Creative Director)
• Segmentation, A/B testing, and continuous optimization
• Deliverability monitoring and list hygiene
• Reporting and analysis — you define the metrics that matter

• Platform ownership (integrations, automations)

   

What We're Looking For

• 5+ years of hands-on email marketing experience, with at least 2–3 years owning the channel independently (not just executing someone else's strategy)
• Proven track record of building and scaling email programs from scratch or significantly improving underperforming ones — with numbers to back it up
• Strong copywriting instincts; you know what a good subject line feels like and why it works
• Deep understanding of segmentation, behavioral triggers, and lifecycle logic
• Solid grasp of deliverability fundamentals (sender reputation, domain warming, spam filters)
• Experience with at least one major ESP (Klaviyo, Customer.io, or similar) at an admin/owner level

• Comfortable with data — you can pull your own reports, interpret them, and make decisions without waiting for an analyst

   

We will not consider candidates with less than 5 years of experience or candidates who have primarily worked in support/execution roles without strategic ownership.

This role requires someone who has run an email channel before — not someone who wants to learn how.

Bonus Points

• Experience in DTC health, wellness, or subscription businesses
• Familiarity with HIPAA-adjacent communications or regulated industries

• Experience replacing or transitioning away from an agency setup

   

Why Join

• Strong in-house creative team to collaborate with — no fighting for design resources
• Real ownership with direct impact on revenue
• Fast-moving environment where decisions get made and things actually ship

• Competitive compensation, fully remote

   

To apply, include a short note on a specific email program you owned, what the situation was when you took it over, and what you changed. Applications without this will not be reviewed.

Overview
We're a B2B SaaS (shared WhatsApp inbox + CRM sync, rated #1 on the HubSpot/Pipedrive/Zoho marketplaces). We already run an established SmartLead setup — warmed mailboxes, lead-sourcing tools, proven sequence templates. We need one focused operator to run and optimize it.

Your one job: get qualified prospects to reply "yes" to a soft call-to-action (e.g. "reply yes and I'll send a one-pager tailored to your company"). That's it. You generate interested replies — our sales lead handles the calls and closing. We are not asking you to book meetings or sell; we're asking you to fill the top of the funnel with people who raised their hand.

What you'll own day-to-day
– Source and segment the right ICP (we sell strongest into WhatsApp-native markets — LATAM, MENA, Iberia, Turkey, Brazil — in services, real estate, travel/hospitality, IT).
– List hygiene: email validation, dedup, suppression, keeping bounce under 3%.
– Build and iterate 3-step soft-CTA sequences (spintax, deliverability-safe, no hard pitch in step 1).
– Run sends across our existing inbox infrastructure; manage warmup, sender health, throttling.
– Triage replies and hand off every "yes"/interested lead cleanly to our sales rep.
– Report weekly on the only metric that matters: positive replies per week (interested / wants-more-info), not opens or clicks.


You must have
– Hands-on SmartLead experience (this is non-negotiable — you know campaigns, sequences, master inbox, warmup, smart-server/IP routing).
– A track record of cold-email campaigns that produced real positive replies, with deliverability discipline.
– Strong written English and instinct for short, human, soft-CTA copy.
– Comfort with lead sourcing + validation tools (SmartProspect / Apollo / LeadMagic or similar).
Nice to have
– Experience selling into LATAM / MENA / emerging markets.
– Familiarity with WhatsApp-based business tools or CRM integrations.
-Experience with LinkedIn Outbound (HeyReach)
