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 Altum

Altum Software is a technology company building AI-powered infrastructure for sales and business automation. We design and develop internal systems that replace manual workflows with autonomous AI agents — from lead qualification pipelines to customer communication layers.

We're a small, senior team that moves fast and builds things that actually work in production. No corporate overhead, no pointless meetings — just interesting problems and real ownership over what you ship.
 

The Role

We're looking for a Software Engineer to join the team building our AI automation infrastructure. You'll work on systems that operate at scale — managing concurrent sessions, orchestrating background jobs, integrating LLMs into real-world workflows, and making sure everything stays stable when it matters.

This is a hands-on engineering role with real architectural responsibility. You'll work directly with the founding team and have full visibility into product decisions.
 

What You'll Be Working On

• Building AI SDR systems — autonomous agents that manage communication pipelines, qualify leads, and move them through the funnel without manual intervention
• Developing browser automation layers that interact with web platforms on behalf of AI agents — handling sessions, actions, and anti-detection logic at scale
• Integrating LLMs (Claude API) for real-time message classification, context-aware response generation, and conversation management across hundreds of active threads simultaneously
• Building the job orchestration layer — queues, background workers, concurrency handling — that keeps everything running reliably at scale
• Connecting the system with external tools: CRM, calendar booking, messaging platforms, alert systems
• Designing internal AI agents that handle repetitive customer-facing workflows autonomously, escalating to humans only when needed

Requirements

• 2+ years of commercial experience in backend or fullstack development
• Strong understanding of system design — queues, background jobs, concurrency, failure handling
• Experience working with relational databases (PostgreSQL or similar)
• Comfortable integrating third-party APIs and navigating unfamiliar documentation quickly
• Systematic thinker — you see how components compose into a reliable whole
• Genuine curiosity about AI tooling — you follow what's happening in the space and like to experiment

Nice to Have

• Experience with Playwright, Puppeteer, or any browser automation framework
• Familiarity with anti-detect browsers or browser fingerprinting concepts
• Prior experience working with LLM APIs (Claude, OpenAI, or similar)
• Understanding of bot detection mechanisms and mitigation strategies
• Experience with Redis / BullMQ or similar job queue systems

What We're Really Looking For

Technical skill matters, but it's not the whole picture. We're looking for someone who picks things up fast, takes ownership without being asked, and genuinely enjoys working at the intersection of AI and automation. You don't need to have done exactly this before — but you should be the kind of engineer who looks at a complex system and wants to understand how it works end to end.

If you've never built browser automation before but the problem space excites you — reach out anyway.

Requirements:

• Strong production experience with both Vue.js and React
• Proficiency with JavaScript / TypeScript for frontend development
• Hands-on experience with Three.js and Canvas-based rendering
• Demonstrable frontend performance optimization experience (page load time, rendering efficiency, working with large or real-time data sets)
• Comfortable working across the stack — willingness to occasionally pivot to backend tasks (backend is primarily C++ with a small Python service)
• Ability to work highly autonomously, proactively clarify requirements and drive work forward with minimal supervision

• Hands-on experience with AI-assisted development tools — e.g. Claude Code and Codex — including AI skills, plugins, and MCP (Model Context Protocol), with a clear understanding of how to boost personal productivity and code quality using AI tooling.

• Hands-on experience with AI-assisted development tools — e.g. Claude Code and Codex — including AI skills, plugins, and MCP (Model Context Protocol), with a clear understanding of how to boost personal productivity and code quality using AI tooling

Nice-to-Have:

• Hands-on experience migrating a frontend from Vue to React (strong plus — the team will be defining its migration strategy together with this engineer)
• Experience rendering large, real-time data streams in the browser
• Familiarity with deck.gl and Leaflet
• WebGL experience beyond Three.js abstractions
• Familiarity with C++ or general backend development

Key Responsibilities:

• Help drive the migration of the application's frontend from Vue.js to React, including advising the team on transition strategy
• Optimize frontend performance — faster page loads and more efficient rendering of heavy real-time 3D scenes and data
• Build and maintain visualization UI components that render synchronized 3D, lidar, and media data
• Take ownership of features end-to-end, proactively clarifying requirements and assumptions
• Collaborate with a primarily US-based team with ~1–2 hours of daily overlap, while working largely independently
• Participate in code reviews and design discussions

About the Project:

You'll join the engineering team of a leading technology company building autonomous mobility and robotics systems. The team develops an internal data visualization platform — essentially a "video and data player" that renders a 3D scene, a lidar feed, and an audio feed in sync, used to inspect and debug the data recorded by autonomous vehicles.

The current focus spans two directions: optimizing the platform's performance and migrating the frontend from Vue.js to React, as the broader engineering organization standardizes on React. This is a long-term engagement for an engineer who is comfortable across the stack, cares about clean and performant code, and can drive features from design to production with high ownership and minimal supervision.
