Job description

This role is with one of Dex's trusted partner companies. We work closely with their teams to truly understand their culture, goals, and what they're looking for, so we can match you with the right opportunity and give you context about the role before you commit to a process.

The role

This company is rebuilding a legacy industry from the inside out. They acquire existing agencies, port their operations onto an AI-enabled platform, and automate the chaos that has defined the sector for decades. This model creates a direct line between engineering output and revenue, offering a rare opportunity to see your work's impact immediately.

This isn't a role where you sit above the work. You'll join a small, fast-growing engineering team, owning an entire domain end-to-end. You'll partner directly with product managers, make architectural calls, and ship pragmatic AI and agentic systems to production — not just prototypes. This is a rare seat to shape a system and team that's still small enough for your impact to be disproportionate and visible.

The work

• Understand legacy workflows, manual workarounds, and per-agency exceptions to identify the highest-leverage automation opportunities.
• Design and implement end-to-end architectures for your domain, making critical technical decisions that connect directly to business outcomes.
• Ship agentic systems and AI-powered features to production, ensuring they hold up under real-world operational load.
• Collaborate closely with product managers to frame problems, define solutions, and drive the roadmap for your domain.
• Be in the code, actively contributing to the codebase while guiding the technical direction and standards.

What You Bring

• You've independently delivered complex systems from idea to production, owning the full lifecycle, not just contributing to parts of it.
• You are strong across the full TypeScript stack, including Node.js on the backend and React on the frontend.
• You have shipped agentic systems that hold up under real production load, applying AI pragmatically to solve business problems.
• You make architectural decisions grounded in operational reality, connecting technical choices directly to business outcomes without being prompted.
• You thrive in high autonomy and ambiguity, with ownership extending past
• the ticket
• in a startup or scale-up environment.
• You are a fluent Russian speaker.
