Remote AI Vibe Developer

Open-Source LLM Training & Agentic Product Engineering (Remote)

Role Summary

We’re hiring an AI Vibe Developer — a product-minded engineer who ships production-quality software quickly by combining strong engineering fundamentals with AI-assisted (“vibe coding”) workflows and modern LLMOps best practices (evals, tracing, guardrails, prompt/version management).

A core requirement of this role is working with an open-source / open-weights LLM that we will fine-tune and run ourselves. You’ll help take it end-to-end — from data → training → evaluation → serving → iteration — and integrate it into real, user-facing product flows.

Responsibilities

1) Build & ship AI-powered product features (end-to-end)

• Deliver features from prototype to production: UI, backend, integrations, deployments, and iteration.
• Use AI coding tools/agents to accelerate delivery while maintaining code quality (tests, reviews, standards).
• Own rollout strategy: feature flags, staged releases, rollback plans, and production support.

2) Design agentic workflows and “AI inside” capabilities

• Implement LLM features such as:
  • Tool/function calling with strict schemas and reliable fallbacks.
  • Retrieval-Augmented Generation (RAG) when needed (grounding, freshness, controllable outputs).
  • Multi-step agent flows (routing, planner/executor patterns, memory/context strategies).
• Integrate external tools/services securely (internal APIs, CMS, analytics, ticketing, CRM, etc.).

3) Open-source LLM training & lifecycle ownership

• Help select the best open-weights model baseline based on quality, licensing, latency, context length, and multilingual support.
• Build and maintain the data pipeline: collection, cleaning, de-duplication, PII redaction, formatting, and dataset versioning.
• Run fine-tuning workflows (e.g., SFT and preference tuning when relevant) with reproducibility and experiment tracking.
• Build a practical evaluation suite (golden sets + edge/adversarial cases) to gate training runs and releases.
• Drive iterative improvement using an error taxonomy: failures → targeted data improvements → retrain → regression checks → release notes.

4) Inference, serving, and performance optimization

• Package and deploy the model for production serving (containerized) with reliability and observability.
• Optimize serving latency/cost via batching, caching, quantization, and safe model routing where applicable.
• Implement system-level guardrails: schema-constrained outputs, input validation, tool allowlists, rate limits, and safe degradation paths.

5) Evals-first development and observability

• Define success metrics (quality, groundedness, refusal behavior, latency, cost, user satisfaction) and track them continuously.
• Instrument LLM flows with tracing (inputs, tool calls, retrieved docs, outputs, model/version, latency, cost).
• Maintain prompt/version control and changelogs; support A/B tests and controlled rollouts.

6) Collaboration & enablement

• Work closely with Product, Design, Data, and QA to translate “vibes” into measurable outcomes.
• Create lightweight playbooks: eval templates, prompt guidelines, incident runbooks, and “how we build with AI here.”
• Improve team velocity by sharing patterns and avoiding AI productivity pitfalls (over-trusting outputs, under-testing).
•  

Requirements

Core Engineering

• 3+ years of software engineering experience (or an equivalent portfolio of shipped products).
• Strong proficiency in Python (required for the training stack), plus at least one of: TypeScript/Node.js, Go, or Java.
• Strong fundamentals: API design, async workflows, testing strategy, debugging, CI/CD, Git, and production ownership.

Open-Source LLM Engineering (Must-have)

• Hands-on experience fine-tuning and/or deploying open-weights LLMs end-to-end: data → training → evaluation → serving.
• Strong understanding of:
  • Tokenization and context budgeting
  • Dataset quality, leakage risks, and evaluation methodology
  • Instruction tuning concepts and preference optimization fundamentals

We are looking for a DevOps Engineer.

This role combines broad architectural responsibility with deep hands-on work across
infrastructure, cloud, Kubernetes, and CI/CD, and includes technical leadership of complex,
end-to-end solutions.


Responsibilities

We need a senior Product Owner who can:

• take real ownership of product outcomes
• run the product delivery machine (discovery → scope → build → ship → measure)
• build structure, clarity, and priority discipline across teams
• grow into Head of Product / CPO responsibilities within months

You’ll work directly with the CEO and engineering leadership.

What you’ll own

1) Product Ownership and Delivery (Core)

• Own one or more key product areas end-to-end (e.g., Scheduling, CRM, Estimating, Work Orders, Invoicing, Reporting/KPIs, Mobile, Integrations).
• Maintain a healthy, prioritized backlog that engineers actually trust.
• Write high-quality PRDs/user stories with acceptance criteria, edge cases, and measurable success metrics.
• Run sprint ceremonies and keep delivery tight: refinement, planning, demos, retros.
• Ensure releases are coordinated with QA, support, implementation, and customer comms.

2) Discovery That Doesn’t Waste Everyone’s Time

• Run customer discovery continuously: interviews, support analysis, win/loss feedback, churn reasons, implementation pain points.
• Convert “noise” into clear problem statements and validated solutions.
• Work closely with Customer Success/Implementation to reduce onboarding friction and support burden.

3) Cross-functional Leadership (No Ego, All Results)

• Align stakeholders across Engineering, QA, Support, Sales, Marketing, Implementation, and Ops.
• Make hard priority calls and explain the tradeoffs like an adult.
• Drive product decisions with data + customer truth, not vibes.

4) Product Ops and Process Maturity (CPO Track)

• Implement product operating cadence: roadmap reviews, quarterly planning, release process, metrics dashboards.
• Set product standards: definition of ready/done, documentation templates, discovery playbooks, decision logs.
• Introduce scalable structure without killing speed.

5) Metrics and Outcomes

• Define and monitor KPIs for your product areas:
  • activation/onboarding success
  • retention and churn drivers
  • feature adoption
  • time-to-value
  • support ticket volume reduction
  • operational efficiency improvements for customers (time saved, fewer mistakes, faster scheduling, fewer re-visits)

• Use telemetry and feedback loops to verify impact after launch.

   

Required experience

• 5–10+ years in Product roles (PO/PM), with at least 3+ years as a senior owner of a B2B SaaS product area.
• Proven record shipping complex workflows (ops-heavy SaaS is a big plus).
• Strong ability to translate messy real-world operations into usable software.
• Excellent writing and specs: PRDs, stories, acceptance criteria, edge cases.
• Comfortable with ambiguity and can make decisions without needing permission every 12 minutes.
• C1 English proficiency

• Ukrainian Native language

   

Strongly preferred

• Experience with field-service platforms: tree care, landscaping, construction, home services, logistics, dispatch, route scheduling, job costing, invoicing.
• Experience with multi-tenant SaaS scaling: permissions, roles, audit trails, data imports, integrations (QuickBooks, payment processors, CRMs).
• Experience creating product analytics baselines and post-launch measurement.

• Experience working with outsourced or distributed engineering teams.

   

Skills and traits (aka the part most people ignore)

• You are decisive and can defend priorities with logic + evidence.
• You’re allergic to fake “Agile theater.”
• You communicate clearly with technical and non-technical people.
• You can say “no” without creating enemies.

• You care about outcomes more than output.

   

Tools / working style

• Jira/Confluence (or equivalent)
• Product analytics (Amplitude/Mixpanel/PostHog or similar)
• Figma (basic competency helpful)
• You write clean documentation and keep the team aligned
