Senior Engineer, AI-Native Development (Ranking Copilot)

Kyiv, Ukraine (Remote)

About the Company
We are a fast-growing product company building an AI-native B2B SaaS platform that transforms how professional services organizations manage and deploy their institutional knowledge.
Our product replaces manual, labor-intensive workflows by consolidating disparate data—such as company expertise, project histories, and team profiles—into a centralized intelligence engine. The platform automatically generates high-impact business proposals, client documentation, and pitch materials, reducing operational effort by up to 90% while improving output quality.

About the Role
We are looking for a hands-on Senior/Staff Engineer or Engineering Lead who has already driven — or has a clear operational vision for — transforming a software engineering team from "AI-assisted" to "AI-native."
What "AI-Native" means in practice:

  • Moving from manual in-IDE prompting to autonomous agent execution, where agents own tasks end-to-end under human supervision.
  • Development driven by clear specifications and acceptance criteria rather than ad-hoc prompts.
  • Shift-Left QA: Verification logic and test cases are designed before implementation begins.
  • Deterministic checks, linters, and architectural constraints replacing unnecessary human code review loops.
  • Turning repetitive dev tasks into reusable AI skills, workflows, and automated pipelines.
  • Systematically converting individual learning and corrections into shared tooling for the whole team.

What You'll Do

  • Audit & Blueprint: Assess current development and QA workflows, then design and execute a staged plan for the team's AI-native transformation.
  • Hands-on Leadership: Work alongside our existing full-stack engineers to establish new conventions, raise engineering standards, and upscale the team.
  • Tooling & Orchestration: Implement and own agentic workflows, moving the stack beyond basic copilots toward fully autonomous execution.
  • Architecture & Scale: Refactor and upgrade the core system architecture to handle a 5–10x increase in multi-tenant load and organizational scale.
  • Process Automation: Automate key high-effort operational tasks (e.g., automated pitch and proposal generation) currently handled manually by company leadership.
  • Deliver Measurable Results: Establish clear milestones to demonstrate tangible velocity and quality gains within the first 1–3 months.

Requirements

  • Technical Leadership: 5+ years of experience in Senior, Staff, or Tech Lead roles within product companies.
  • AI-Native Expertise: Practical experience designing, building, or adopting agentic workflows across a team (beyond personal use of AI assistants).
  • Strong Engineering Background: Full-stack or backend focus with a deep understanding of modern web ecosystems (Core: Node.js / TypeScript).
  • Product & Business Mindset: Comfortable making autonomous technical decisions that balance business priorities with long-term engineering health.
  • Architectural Scaling: Proven track record of refactoring systems for high availability, multi-tenancy, and performance.
  • Startup Drive: Comfortable navigating an active transformation phase with high autonomy and fast iteration cycles.

Tech Stack & Tooling

  • Core: TypeScript, Node.js, React, Next.js, NestJS
  • Infrastructure: Cloud (GCP / Azure), GitHub Actions, Docker
  • AI Tooling: Claude Code, Cursor, custom agent frameworks / orchestration workflows
