About the role and the client:
We are looking for a Chief Technology Officer (CTO) for a consulting company delivering hardware and software solutions for defense projects.
The CTO will be the primary technical authority, responsible for system architecture, product viability, and engineering leadership — from idea conception to field deployment.

This role is ideal for a systems engineer and technical leader capable of designing complex end-to-end solutions and managing multi-disciplinary teams (hardware, embedded, software, AI/DSP).

In defence technology, mistakes in architecture are costly.
This role is about responsibility, systems thinking, and creating technologies that work in real operational conditions, not just look good in presentations.

Key Responsibilities:
- Define the company’s technical strategy and R&D directions.
- Design end-to-end systems (sensor → compute → comms → operator / effect).
- Provide architectural oversight for hardware, embedded, AI/DSP, and software teams.
- Participate in presales and technical client discussions.
- Evaluate and select new projects or solutions (go/no-go decisions).
- Collaborate with field teams to analyze real-world testing results.
- Manage the transition from prototype to working product and scalable solution.
- Build, mentor, and develop engineering teams.
- Select technologies, define architecture, and establish engineering processes.

Requirements:
- 5+ years of experience in systems engineering / embedded / robotics / avionics / radar / RF / EW / UAV / defense technology.
- Proven experience integrating hardware + embedded + software.
- Strong systems-level thinking and experience designing complex technical solutions.
- Understanding of field constraints: latency, reliability, maintainability, and real-world operational conditions.
- Track record of taking products from prototype → MVP → deployment/production.
- Experience managing engineering teams.
- Experience in client-facing technical roles / presales / solution architecture.
- English: Advanced.

Preferred Qualifications:
- Experience in one or more areas: UAV / RF / EW / radar / sensing / avionics / robotics.
- Ex-military engineer or experience working closely with operational military units.
- Experience with serial production or scaling complex systems.
- Proven ability to build R&D or engineering departments from scratch.
- Background in miltech / defence / robotics / telecom hardware companies.

Ideal Candidate:
- Thinks in systems, not just components.
- Can confidently say “this won’t work” and propose alternatives.
- Focused on results in the field, not presentations.
- Capable of making technical decisions under uncertainty.
- Strong leadership in client and engineering team interactions.
- Motivated to build products from scratch and shape the company’s technical direction.

What the Company Offers:
- Participation in defence technology projects.
- Exposure to hardware + embedded + software products.
- Active involvement in presales and technical strategy.
- Health insurance.
- 24 days of vacation.
- Office/lab in Kyiv.

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.
 

What We Offer

• Fully remote, async-friendly environment
• Flexible schedule — outcomes over hours
• Direct collaboration with the founding team
• Real ownership over technical decisions
• Long-term engagement for the right person

• Experience setting up reliability practices (SLI/SLOs, incident management and post-mortems) or observability (metrics/logs/traces) from scratch;

• Domain experience in high-load e-commerce, Fintech, or iGaming projects.

   

🥷 YOUR POWER-UPS SOURCE:

• Spontaneous weekend from the CEO;
