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)

• 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.
