We're building an AI-powered document processing platform that automates complex back-office workflows — from intake and validation to approval and ERP synchronisation. The system is already in production and handles real financial flows; you'll be joining at the scaling stage.

What you'll work on

• AI orchestration layer: LLM tool-calling pipelines (Claude / OpenAI), MCP server (4 domain tools), context and retry management
• Integrations: Microsoft 365 Graph API, DocuSign REST API, Azure Document Intelligence
• Validation & routing engine: business rules, confidence scoring, exception handling

• Frontend: React 18 + TypeScript + Tailwind dashboard (agent status, approval queue, analytics)
• Infrastructure: Docker, GitHub Actions CI/CD, Azure / AWS cloud

Required

• Node.js + TypeScript — 4+ years in production, architecture-level decisions
• LLM API integration — tool calling, prompt design, context management (OpenAI, Anthropic, or Gemini)
• REST API design + OAuth2/OIDC implementation
• PostgreSQL — schema design, query optimisation, migrations
• Microsoft 365 Graph API or similar enterprise API (SharePoint, OneDrive, Teams)
• Azure Document Intelligence / AWS Textract / similar document AI service

• OpenTelemetry — metrics, traces, structured logs
• Tailwind CSS + shadcn/ui
   

We're looking for

Someone who has shipped AI-integrated features in production — not just experimented with them. You take ownership end-to-end: design → implementation → deployment → monitoring. You can make pragmatic architecture calls and explain trade-offs clearly.
 

Senior bar: you've led technical design of at least one non-trivial integration (enterprise API, document pipeline, or payment flow), and you don't need to be told what to research.
 

Offer

• Fully remote, async-friendly, EU time zone overlap (11:00–19:00 Kyiv)
• Small product team no bureaucracy, direct access to founders
• 24 days paid leave + public holidays
• 3-month probation period

About OneTablet
OneTablet is a restaurant delivery management platform that helps restaurants sell more and operate better across DoorDash, Uber Eats, Grubhub, and other ordering platforms. We optimize the signals that platform algorithms use to rank restaurants, enhance menus with AI, and expand sales surface — so restaurants make more money, measurably, in dollars.

We operate AI-first. AI isn't a buzzword here — it's how we actually run. We use AI agents internally to monitor stores, investigate issues, and handle operational work that traditional teams do manually. Our support team is built around this: smaller, sharper, more technical, and every person has real ownership over outcomes — not just tickets.

- Practical experience with MCP (Model Context Protocol) — building servers, designing tools, connecting agents to systems
- Experience creating and managing AI agents: skills, sub-agents, hooks, back-pressure mechanisms, context architecture
- Understanding of the full agentic engineering stack

Engineering
- Strong full-stack experience (Node.js / TypeScript + React)
- Hands-on experience with GraphQL in production
- UX sensitivity — you care how things feel, not just if they work

About HELO Solutions

HELO Solutions is an AI consulting and product development company. We build production AI systems — agents, automation platforms, and intelligent workflows — for enterprise clients across industries including CPG, financial services, legal, and music. We also develop our own AI products. We are a small, high-output team that ships fast, operates with minimal bureaucracy, and holds a high bar for work that actually runs in production and gets used.

About the Role

We are hiring an AI Engineer who has built agents that are live in production at real companies — not demos, not prototypes that died after a pitch, not research projects. We need someone who has shipped agentic systems that enterprises depend on every day, and who understands the full lifecycle: scoping the business problem, designing the agent architecture, integrating with messy enterprise systems, building evaluation and monitoring, and keeping it running reliably.

This role sits across two priorities equally: building our internal multi-agent AI platform and delivering agent-based solutions directly to enterprise clients. You will work closely with our engineering team and the Managing Partner. You will have significant autonomy and direct impact on both the product and the business.

Responsibilities

• Design, build, and deploy AI agents and multi-agent systems that solve real business problems for enterprise clients.
• Architect and implement agent orchestration — coordination, handoffs, shared state, and communication between specialized agents within our multi-agent platform.
• Integrate agents with enterprise systems (ERPs, CRMs, accounting platforms, APIs) to execute workflows end-to-end in production environments.
• Build evaluation frameworks and production monitoring for deployed agents — logging agent decisions, tracking accuracy, cost, and latency, and implementing feedback loops.
• Work within client systems to understand existing workflows and translate messy business processes into agent-executable architectures.
• Identify and codify repeatable deployment patterns across engagements to accelerate future delivery.
• Maintain deep, current knowledge of LLM capabilities, agent frameworks, implementation patterns, and the evolving AI product development stack.
• Deliver technical artifacts including agent skills, sub-agents, API integrations, and supporting infrastructure that will be used in production workflows.

• Contribute to internal product development, shaping the architecture and capabilities of our platform alongside the engineering team.

   

Requirements

• Production agent experience — You have built AI agents that are currently running in production for real companies. You can point to systems you built that people use every day.
• Python proficiency — Strong programming skills with Python as your primary language. You ship clean, maintainable production code.
• LLM fluency — Deep working knowledge of prompt engineering, context window management, and model selection. You know when to use a smaller model vs. a frontier model and why.
• Enterprise integration experience — You have connected agents to real business systems: ERPs (Acumatica, NetSuite, SAP), CRMs (Salesforce, HubSpot), accounting platforms (QuickBooks, Xero), or comparable enterprise APIs.
• Evaluation and monitoring in production — You have built observability into agents. You know how to log agent decisions, track accuracy and cost, and build feedback loops that improve agent performance over time.
• Multi-agent orchestration — You have designed or built systems where multiple specialized agents coordinate, hand off tasks, and share state to accomplish complex workflows.
• High agency — You can take a messy business problem and turn it into a working agent architecture without hand-holding. You thrive in ambiguity and move fast with minimal direction.
• Portfolio / case study — You must be able to walk us through at least one agent system you built that is live and being used by a real company. We want to understand the business problem, your architecture decisions, and how it is performing.

Nice-to-Haves

• TypeScript, Java, or a strong second language beyond Python.
• Customer-facing or consulting experience — you have worked directly with clients or stakeholders to scope and deliver technical projects.
• Domain experience in financial services, CPG, legal, or the music industry.
• Cost optimization thinking — token management, caching strategies, model routing to keep agent operating costs viable for clients.
• Experience with workflow orchestration tools (Temporal, Airflow, Step Functions, or similar).

• Former technical founder or early-stage startup experience — you have worn many hats and shipped under resource constraints.

   

How to Apply

Send us your resume and a brief write-up of an agent system you built that is live in production. We want to know: What was the business problem? What was your architecture? How is it performing? If multiple people contributed, tell us which part was yours. Keep it concise — a few paragraphs is plenty.

What We Offer

• Remote-first, global team — work from anywhere.
• Direct impact — you will shape both our products and our client engagements from day one.
• Small team, no bureaucracy — decisions happen fast, your work ships fast.
• Exposure to diverse enterprise AI challenges across multiple industries and verticals.

• Competitive compensation dependent on experience.
