Hello.

We are looking for a Senior Node.js Developer to join Ohayu (https://ohayu.com). We are building the easiest way for travelers to stay online anywhere in the world. We’re a fast-scaling B2C mobile + web app (iOS/Android/Web) that lets people buy eSIM data plans in minutes - cheaper than roaming, no SIM shops, no hassle. Thousands of travelers already use Ohayu worldwide, and we’re just getting started.
Our ambition is bigger than eSIM: we’re evolving Ohayu into a full Travel App that makes every journey smoother.

What you’ll do:

This role is for someone who wants real ownership and real product impact.

• Own integrations with third-party APIs (telco/eSIM providers, payments, analytics, etc.) - abstraction layers, reliability, observability, edge cases, scale.
• Shape backend direction: architecture decisions, technical standards, and how we build/ship safely at speed.
• Enable rapid experimentation: implement backend changes for A/B tests and product iterations that directly impact conversion and retention.
• Build and maintain production-grade services: migrations, logging, alerts, uptime, and smooth releases.

What we’re looking for:

• 5+ years of backend with OOP experience
• 5+ years with Node.js + TypeScript
• 2+ years with NestJS
• 5+ years with MySQL / MariaDB / PostgreSQL
• Hands-on production experience: migrations, monitoring/logging, alerts, process managers (pm2/supervisor), incident mindset
• You work independently, communicate clearly, and take responsibility end-to-end
• At least intermediate English level (all work communication is in English)

Nice to have:

• Experience with high-load systems
• Experience supporting A/B testing and experimentation platforms/pipelines

Why to join us:

• Direct product impact: what you ship gets used immediately by real travelers.
• Ownership: you’re not “a contributor,” you’re a builder helping set the backend direction.
• Product engineering culture: we care about UX and conversion as much as we care about clean code.
• Fast pace, real learning: constant iterations, clear feedback loops, real-world constraints.
• Genesis ecosystem: access to strong expertise, resources, and networking.
• Benefits: health insurance, 20 paid vacation days, annual performance review with clear salary progression.

Work format: Possibility to work fully remotely or from our offices in Warsaw, Kyiv or Lviv.

Join us in reshaping the future of connectivity.

We are a real estate lead generation platform.

Every month, we generate 3,000–5,000 homeowner leads (people who fill out a form indicating potential interest in selling their property).

We sell these leads to real estate investors (wholesalers, fix & flip, buy & hold, lenders).

2. The problem we are solving

Right now, the system is inefficient in 3 major ways:

1. Low contact rate

• ~60% of leads do not answer investor calls
• Result: wasted acquisition cost, poor investor experience

2. Poor qualification

• Not all leads are real sellers
• Many are low intent, unmotivated, or just exploring

3. Wrong investor matching

• Leads are distributed without deep understanding of:
  • seller situation
  • best exit strategy

👉 Result:

• lower conversion rates
• refunds / dissatisfaction from investors
• lost revenue

3. What we want to build

We are building an:

AI-powered Lead Qualification & Routing System

This is not just an AI caller.

This is a full decision-making layer that:

1. Contacts the lead
2. Qualifies the seller
3. Scores intent
4. Matches them with the right type of investor

4. Your role

You will own the design and implementation of this system.

This includes both:

• technical architecture
• logic of how decisions are made

5. Core components you’ll build

1. AI Calling Agent (Voice SDR)

• Automatically calls new leads
• Handles conversations naturally
• Collects key seller information

Goal:
→ maximize contact rate & engagement

2. Qualification System

Extract and structure:

• Motivation (why sell?)
• Timeline (urgent vs future)
• Property condition
• Price expectations

Output:
→ structured data + qualification tags

3. Lead Scoring Model

Classify leads into:

• High intent (ready to sell)
• Medium intent (nurture)
• Low / no intent
• Invalid / spam

Goal:
→ increase quality of leads delivered to investors

4. Intelligent Lead Routing

Match each seller with the best investor type:

Examples:

• Distressed property → wholesaler
• Good condition → retail / fix & flip
• Financial need → lending / financing

Goal:
→ maximize deal probability per lead

5. Multi-Touch Follow-Up System

If the lead doesn’t respond:

• Retry calls (timing optimization)
• SMS follow-ups
• Voicemail drops

Goal:
→ extract maximum value from every lead

6. Optimization Layer

• A/B testing call scripts
• Improving prompts
• Tracking conversion metrics

Goal:
→ continuously improve performance

6. What success looks like

Within 2–3 months, we expect measurable improvements:

• Contact rate: +30–50%
• Qualified leads: +25%+
• Revenue per lead: +20–40%
• Lower refund rate from investors

7. What matters most

This role is NOT about:

• building “cool AI demos”
• experimenting without outcomes

This role IS about:

• driving revenue through better decisions
• improving conversion across the funnel
• building systems that actually work in production

8. What we expect from you

• Ability to design end-to-end systems (not just components)
• Strong understanding of LLM-based workflows
• Experience with conversational / voice AI (or strong ability to learn fast)
• Product thinking (conversion, funnels, trade-offs)
• Ownership mindset

9. First milestone (very important)

Your first goal:

Launch a working AI calling + qualification MVP
that improves contact rate and produces structured lead data.

Speed matters more than perfection.
