At c3 we're building a spatial intelligence data layer. We're a startup based in the UK, and are building an engineering team to focus on research and development of our proprietary models. 

Ideally we are looking for someone with: 

Multi-session SLAM / map merging / long-term localization / 3D registration experience

Ideal past experience:

Autonomous-driving mapping, warehouse/robot localization, AR persistent maps, LiDAR map differencing, construction progress monitoring, digital twins, or long-term robotics localization.

Requirements

* Strong background in 3D computer vision and geometric perception: point clouds, meshes, depth maps, coordinate transforms, registration, visibility/occlusion reasoning, and spatial change detection.

* Hands-on experience with real RGB-D / LiDAR / depth-sensor data. You should have dealt with noisy depth, incomplete scans, moving objects, partial overlap, and sensor/calibration errors.

* Strong understanding of 3D registration, including ICP variants, robust/global registration, geometric descriptors, RANSAC/TEASER++-style approaches, and failure detection.

* Experience solving multi-session or temporal mapping problems: comparing the same physical environment captured at different times.

* Familiarity with SLAM / visual-inertial odometry. You should understand accumulated drift, scale error, loop closure, and how errors in scan generation propagate downstream.

* Strong Python and PyTorch skills, with experience building production-quality evaluation and inference pipelines.

* Experience with learned feature matching such as LightGlue, SuperGlue, LoFTR, or equivalent is useful, particularly for cross-scan registration.

* Experience with synthetic data generation / simulation for augmentation and controlled failure-case generation.

* Robotics, autonomous systems, mapping, AR/VR, drones, or defence perception experience is highly relevant.

* Fluent English.

* Kyiv-based preferred; hybrid or remote considered.

What you will do

* Build a robust scan0 -> scan1 registration pipeline that aligns mostly-static structure while remaining insensitive to moved furniture and other transient objects.

* Handle partial overlap, occlusion, missing observations, drift, and scale differences between scans.

* Build temporal change detection that distinguishes:

    * object removed / added,

    * object moved,

    * surface or condition changed,

    * area unchanged,

    * area not observable / insufficient evidence.

* Develop visibility and free-space reasoning so that “not seen” is not incorrectly classified as “gone.”

* Build multi-stage registration using geometric and learned features, followed by robust local refinement.

* Define confidence / failure detection for registration and comparison results rather than forcing a result from bad scans.

* Develop condition/defect classification and severity scoring once geometric correspondence is sufficiently reliable.

* Create synthetic perturbations and generated training/evaluation data covering known failure modes.

* Own evaluation against ground truth, including registration success rate, false positive/negative change detection, localization accuracy, and uncertainty calibration.

* Evaluate alternative scene representations, including 3D Gaussian Splatting, NeRFs, TSDFs, occupancy/SDF representations, where they materially improve temporal comparison.

We run a portfolio of DTC ecom brands and test new products constantly. When one starts working, we push hard on it, that's where you come in.

You'll work closely with a small team of editors who turn your scripts into ads. This is why it's important that you not only make a script but create visual and auditory guidelines for the editors to follow.
What you'll do
Write ad scripts for whatever product is currently being scaled.
Research the product, the customer, the reviews, the competitors - fast
Build angle and hook variations around what's already working.
Study the winning ads in the space and pull what applies.
Hand off clean, shootable scripts (VO, on-screen text, visual notes) to editors.
Iterate based on performance data from the previous batch.

CreditBooster.ai’s mission is to help every American understand, build, and own their credit. We’re an AI-native credit platform, live on the App Store and Google Play, with real paying customers and a small remote team across the US and Europe. Our users work on improving their credit, learn how credit actually works, and find credit products matched to their profile. We grew 2,211% in six months.
 

The problem you’d own

Credit improvement has the slowest feedback loop in consumer fintech.

Improving a credit score is a long journey, and it moves in long cycles. Reports refresh once a month. Real change takes many months more. Between those moments a user’s score does not move and nothing visible happens. Every product in this category inherits that silence. Most of them fill it with noise, or with numbers they cannot stand behind. We would rather fill it with something true, and that is the design problem you would own.

The second half of it is comprehension. Credit is genuinely confusing, and most people arrive without a clear model of how it works or what to do first. Building that understanding, and making it feel like real movement long before the outcome arrives, is as much of this role as the mechanics are.

Your job is to design the system that fills that gap: a motivation and education layer that makes a 30-day wait feel like forward movement, without ever lying to the user about their score.

That last clause is the hard part, and it’s why this role needs a specialist. We operate under CROA and app-store rules. We cannot promise a score outcome, we cannot imply a guaranteed result, and we cannot reward users for taking on debt. Every mechanic you design has to create genuine momentum inside those constraints. If you’ve only ever gamified things where you could dangle the outcome, this will be a harder and more interesting problem than you’re used to.
 

Where you might come from

We’re as interested in game designers as in product people. If you’ve built progression systems, quest structures, meta systems, or in-game economies, and you want to point that craft at something that changes a person’s financial life rather than their score in a match, this is that job. The discipline transfers. The subject matter is what changes.

To be direct about one thing: this is not an iGaming or casino retention role, and that experience is not what we’re looking for. Bonus mechanics, lootboxes, and win-back offers are the opposite of the playbook here.
 

What you’d own

You’d work alongside our product manager.

• The engagement model. Define the progression system end to end: what counts as progress between report pulls, how it’s earned, how it’s shown, what it unlocks. We have an internal brainstorm covering XP, credit-health levels, streaks, and quest-framed progress. Treat it as raw material to argue with, not a spec to implement.
• Notifications and lifecycle messaging. Our push and email today are functional and forgettable. We want a messaging system built on a metaphor a user can hold in their head, delivered on a cadence that earns attention instead of burning it.
• First-run and education. Design what a new user sees in their first ten minutes and their first month. This is the single biggest lever we have on how a new user starts.
• The retention instrument panel. Decide what we measure, instrument it with our PM and engineers, and hold yourself to it. You should be able to say which mechanic moved which cohort, and kill the ones that didn’t.
• Experiment design. Set up the tests, call them honestly, and write down what we learned. We have PostHog, Amplitude, and RevenueCat in place.
   

What we’re looking for

• You’ve shipped a real system that survived contact with users. Progression, levels, quests, missions, streaks, meta systems, in-game economies, habit loops. In a game or in a product, it doesn’t matter which, as long as it went live and you can talk about what it changed using numbers. Not a case study, not a concept deck.
• You can write the document. A GDD, a systems spec, an engagement model, whatever your discipline calls it. You define the rules, the balance, and what the system refuses to do, clearly enough that designers and engineers can build from it.
• You reason from behavioral science, not from a pattern library. Self-determination theory, the Fogg behavior model, variable reward, loss aversion, the difference between a habit and a compulsion. You can explain why a mechanic works, and you can tell when the honest version of it is weaker than the manipulative version and choose the honest one anyway.
• You are comfortable being the person who says no. Half of good gamification is deleting mechanics. Points for their own sake, leaderboards that shame people, streaks that punish a missed day during a hard month. You’ve killed features like these before and you can explain why.
• You work in the constraint, not around it. Regulated, compliance-bound, or safety-critical product experience is a strong signal. Health, education, finance, insurance.
• You’re hands-on. We’re a small team. You will write the specs, sit with the designers in Figma, brief the engineers, read the dashboards, and argue with the CEO. There is no team under you and no one to delegate to.
   

You may be a good fit if you have

• 4+ years in game design, product design, behavioral design, or learning design, with at least 2 owning a progression, economy, or engagement system end to end
• Evidence a system you built changed how people behaved, and the honesty to also describe something you shipped that didn’t work
• Fluency with analytics and experimentation tooling, and the confidence to design a test that can actually fail
• A plus, not a requirement: experience at a company known for doing this well, such as Duolingo, SoFi, Noom, Headspace, Chime, Credit Karma, Peloton, Babbel, or Strava, or on a live game with real progression and economy systems
• Working English at C1 or above. Our team speaks Russian and Ukrainian internally, but all product artifacts, tickets, and customer-facing copy are in English
   

Nice to have

Consumer subscription experience, especially where the value takes weeks to arrive. Formal background in psychology, behavioral economics, or instructional design. Game design or live-ops experience. Experience in credit, lending, or another product where the user’s outcome is partly out of the product’s control.
 

How we work

Fully remote. You’ll need overlap with Chicago mornings, roughly 8 to 11am CT, for standups and demos. We’re open to full-time and to a focused fractional engagement if that’s how you work best. Tell us which you want and we’ll talk.
 

How to apply

Send us one system you shipped. Tell us what it was supposed to change, what it actually changed, and one mechanic you removed and why. First step is a 30-minute conversation. No take-home before that.

We're building a modern accounting SaaS, think QuickBooks, but genuinely nice to use. The backend is a forked Akaunting (Laravel) core owned by a dedicated backend engineer. Your job is everything the user sees: a fast, beautiful, mobile-first Next.js app that makes accounting feel less like accounting.

• Turn Figma or scoped ideas into motion-aware UI
• Consume the backend's REST/JSON API; collaborate closely with the backend engineer on API shape
• Small stuff: empty states, loading states, error states, keyboard shortcuts, accessibility
