AI–Native Product Team

The Role

As a Senior Fullstack Engineer on one of our new AI–native squads, you will own entire features from database to UI. Our stack runs on AWS with PHP/Laravel and Node.js/NestJS powering the backend services, and React with TypeScript on the frontend. You will be expected to leverage AI coding assistants, automated testing tools, and generative AI workflows as core parts of your daily process—not as occasional novelties.

What you will be responsible for:

• Own and deliver features end–to–end across the full stack (backend services, APIs, frontend interfaces, and data layers)
• Design, build, and operate production systems in a payroll domain where correctness and reliability are non–negotiable
• Use AI coding tools (e.g., Claude Code, Cursor, Copilot) as a daily force multiplier for writing, reviewing, and refactoring code
• Write and maintain automated tests with AI–assisted generation, aiming for high coverage with minimal manual effort
• Participate in lean team rituals: async–first communication, lightweight code reviews, and continuous deployment
• Collaborate closely with product and design in a small squad to scope, estimate, and prioritize work
• Contribute to defining and evolving our AI–augmented engineering practices and toolchain
• Take shared ownership of operational concerns: monitoring, alerting, incident response, and on–call rotations

What We Are Looking For

Must–haves:

• 5+ years of professional software engineering experience with meaningful exposure to both backend (PHP or Node.js) and frontend (React/TypeScript) development
• Strong proficiency in our core stack: PHP/Laravel and/or Node.js/NestJS on the backend, React with TypeScript on the frontend
• Hands–on experience with AWS cloud infrastructure, relational databases, and API design (REST or GraphQL)
• Demonstrated comfort with AI–assisted development workflows—you already use AI tools regularly and can articulate how they change your process
• Strong fundamentals in testing: you know when to write a unit test, an integration test, or lean on AI–generated test suites
• Excellent async written communication—you document decisions, write clear PRs, and can drive alignment without meetings
• Ownership mindset: you do not wait for someone else to write the migration, fix the flaky test, or update the runbook

Nice–to–haves:

• Experience in payroll, HR tech, or fintech domains where precision and compliance matter
• Familiarity with prompt engineering, AI agent frameworks, or building LLM–powered features into products
• Experience migrating or integrating between PHP/Laravel and Node.js/NestJS services
• Experience working in small, high–autonomy teams (startups, platform teams, or similar)
• Background in QA or testing automation—understanding quality from first principles
• Contributions to developer tooling, CI/CD pipelines, or internal platform improvements

Why This Role Is Different

We are not adding “AI” to a job title for marketing purposes. We are restructuring our entire
engineering organization around a thesis: small teams of strong fullstack engineers, deeply
integrated with AI tools, can outperform larger traditional teams in speed, quality, and developer
satisfaction.

What this means in practice:

• You will not hand off work to a separate QA team—you own quality, aided by AI–powered testing and code review
• You will not wait on a backend engineer to build your API—you build the whole feature
• You will have real input into the tools and workflows the team adopts—this transformation is being built collaboratively
• You will work in a team of 2–3, not 5+, which means less coordination overhead and more building time

Benefit offerings include:

• 20 paid vacation days annually
• Paid public holidays based on your country of residence
• Unlimited sick leaves
• Comprehensive premium health insurance coverage

We're a fast-growing tech company building modern, innovative digital products — and we're looking for a Full-Stack Developer to join our team in Lviv. If you're comfortable on both sides of the stack, enjoy owning features end-to-end, and want to work in a team that values engineering quality, we'd love to hear from you.

What you'll be doing

You'll work as part of a cross-functional team to build and maintain full-stack features — from crafting responsive, user-friendly interfaces to designing scalable server-side architecture and APIs. Our frontend stack includes React, Next.js, TypeScript, Redux, GraphQL, SCSS, Material-UI, and Webpack. On the backend, we work with Node.js, Express, NestJS, PostgreSQL, MongoDB, JWT, Socket.IO, AWS (DynamoDB, S3, EC2), Firebase, and Heroku. We also integrate with third-party services such as Twilio, SendGrid, Google Maps, MapBox, and WebRTC.

What we're looking for

Frontend

• Solid experience with React and modern React hooks
• Confident use of modern JavaScript (ES6+) and TypeScript
• Strong command of HTML5, CSS3, and SCSS
• Experience with Redux or other state management tools
• Ability to build responsive, cross-browser compatible layouts

Backend

• Solid hands-on experience with Node.js
• Practical experience with Express.js and/or NestJS
• Experience working with ORM tools
• Proficiency in SQL databases (MySQL / PostgreSQL) and NoSQL databases
• Experience designing RESTful APIs and integrating with third-party services

General

• Experience with Git and version control workflows
• Ability to work across the full product lifecycle — from feature design to deployment
• Responsible, self-motivated, and comfortable working both independently and as part of a team

What we offer

• Full-time, in-office position in Lviv
• Official employment and a competitive salary based on your skills and experience
• Company-provided equipment
• A well-structured work schedule
• A friendly, supportive team and a comfortable office environment
• Mentorship and guidance from experienced colleagues
• Interesting and technically challenging projects to grow on

How to apply

Send us your CV — we review every application and get back to candidates promptly. This could be the start of something great.

The Role

You'll be the primary engineer behind Parqlet — owning the backend, the database, the mobile app, and the infrastructure that ties them together. This is a senior, autonomous role: you'll set the technical direction, decide what to build next, and ship it. If you like owning a whole product end-to-end rather than a narrow slice, this is that job.

The core functionality is done. Your job is to keep it stable and correct as our first building goes live, then build the next wave from the roadmap:

Rewards exchange — residents redeem credits for gift cards and local business perks

Garage camera integration — license plate recognition so buildings automatically verify every vehicle in the garage is authorized

Revenue share with buildings — a model where the platform pays for itself as the building's parking pool grows

Multi-building scale — onboarding new buildings, each in its own isolated environment

What you'll own

The API & business logic — booking flows (auto-assign, holds, broadcast/offer, approvals), the credit/wallet system, and the rules that keep them correct.

Payments — Stripe integration end-to-end: PaymentIntents, webhooks, idempotency, subscriptions/invoices, and the reconciliation and safeguards that make sure no one is ever double-charged or under-credited.

The database — PostgreSQL schema design, migrations, data integrity, and query performance. You're comfortable owning schema changes and migration tooling in production.

The mobile app — a React Native / Expo app: features, releases through EAS to TestFlight and the App Store, and the native integrations (Stripe, push notifications).

Infra & reliability — CI/CD, deploys, observability, and hardening the system so incidents are rare and quick to resolve.

BuildingLink data integration — syncing resident and unit data from the building's management system via FTPS file exchange, keeping our database current with move-ins, move-outs, and spot assignments.

Our stack

Backend: Node.js, TypeScript, Hono, Drizzle ORM, PostgreSQL

Payments & services: Stripe, Firebase Cloud Messaging (push), object storage (MinIO/S3-compatible)

Mobile: React Native, Expo (expo-router), EAS builds, native Stripe SDK

Infra: Docker, GitHub Actions CI/CD, migration-driven schema management

Auth: OTP + JWT

You don't need to have used every one of these, but you should be genuinely strong on the backend/database side and able to move confidently across the whole stack.

What we're looking for

6+ years building and running production full-stack systems, with real depth on the backend and databases (SQL schema design, migrations, transactions, avoiding race conditions).

Hands-on experience with payments is a must-have (Stripe or similar) — you understand webhooks, idempotency, and why correctness with money is non-negotiable.

Solid TypeScript/Node and comfort in a React Native / mobile release workflow (or a track record that shows you'll pick it up fast).

Strong instincts for security (authorization, data protection) and reliability (observability, safe migrations, graceful failure).

Excellent written communication — you keep work visible, flag risks early, and write clear PRs and updates without being asked.

You will Identify opportunities to improve lagging metrics across customer acquisition, retention, product adoption, and revenue. Design and implement initiatives to address them

How we work — and who thrives here

AI-accelerated by default. We'll provide you a Claude subscription (Claude Code) and tools like CodeRabbit for automated reviews. We expect you to lean on them heavily to ship faster and with higher quality — and to review the AI's work critically. You direct the tools, catch what they miss, and make sure the codebase stays clean and coherent as it grows. AI writes a lot of the code; you own its quality.

We run on Loom videos and written updates — you should be comfortable recording a quick walkthrough instead of scheduling a meeting. Sync calls happen in the afternoon (CET).

Total ownership. You're trusted to be accountable for outcomes.

Productivity and quality, together. We move fast, but we don't ship sloppiness into a payments product. Tests, code review, clean migrations, and thoughtful design are how we go fast sustainably.

Communicate proactively. Clear and frequent communication is what makes it work — status, tradeoffs, and "here's what I'm about to do" over silence.

Inception-1 is a fast-growing product company. We create AI-driven products that help people feel more connected and less alone. Our mission is to build meaningful digital experiences that blend technology with empathy — and to prove that AI can be both human and transformative.
We are looking for a Fullstack Engineer with a strong backend foundation who is ready to take ownership of features from idea to release.

• English at Intermediate level or higher.
   

Nice to have:

• Experience integrating LLMs, AI APIs, or machine learning services into products.
• Strong grasp of product analytics.
• Experience in product feature design and testing.
   

What we offer:

• Flexible work format: you can work remotely or from our comfortable office in Kyiv’s Podil district — whatever works best for you
• Our office has secure shelters and uninterrupted internet, water and electricity. If you choose to work from the office, we’ll take care of the routine: breakfasts, lunches, snacks and fruits, lounges, massages, and other office-life benefits are waiting for you
• Flexible work schedule

LCNC Platform Experience

Experience designing and implementing drag-and-drop builders (e.g., visual editors, form builders, workflow designers) - Advantage

Experience building end-to-end low-code / no-code platforms, including visual modeling, rule engines, and runtime execution layers - Advantage.

Core Idea in LCNC Context

In an LCNC platform, end-users compose applications by dragging/dropping/recombining blocks (pre-built components with their own data schema, UI, validation rules, permissions, etc.). When a user connects a "User Profile" block with a "Billing Info" block (and maybe a "Custom Metadata" block), the platform must:

1. Dynamically compute the resulting data shape (merged schema).
2. Preserve all metadata (decorators, validation rules, OpenAPI extensions, UI hints, relations, etc.).
3. Generate runtime artifacts efficiently: TypeScript interfaces for backend services, JSON Schema for forms/validation, GraphQL types, database migrations, etc.
4. Do it at scale without exploding memory or compile time.

For a Team Lead role on a Low-Code/No-Code (LCNC) platform, this question is not just a syntax check. The interviewer is testing your architectural vision for metadata-driven development, visual modeling, and system scalability.

In an LCNC platform, you are building the blocks that other people use to build applications.

Why It Matters for a Low-Code/No-Code Platform

• Visual Schema Composition: LCNC platforms rely on users dragging and dropping blocks (e.g., combining a "User Profile" block and a "Billing Info" block). IntersectionType() is exactly how you dynamically merge those two visual schemas on the backend into a single, valid API contract.
• Dynamic Metadata Generation: Your platform must automatically generate API documentation and forms based on user layouts. You need utilities that preserve decorator metadata at runtime to achieve this.
• Performance and Memory: Creating thousands of distinct, hardcoded classes for every user configuration wastes server memory. Class composition helpers allow you to create dynamic schemas efficiently.

What to Have for this position

• 7+ years as a Full Stack Developer
• 3+ years in Backend web development in Node.Js
• 5+ years with React +Redux frontend web applications.
• 2+ years leading design and delivery
• Deep Knowledge and experience with JavaScript, TypeScript
• Experience with Databases - MongoDB
• Deep knowledge of software architecture design and REST API
• Experience owning your code quality by writing tests, automation, and monitoring dashboards
• Strong object-oriented design and development capabilities
• B.Sc. degree in Computer Science or equivalent practical experience
• Experience in SaaS or multi-tenant or cloud-based environments or scalable platforms (born in cloud or cloud native companies) - Must
• Experience in working in a foundation/platform team - Advantage
• Experience designing and implementing drag-and-drop builders (e.g., visual editors, form builders, workflow designers) - Advantage

• Experience building end-to-end low-code / no-code platforms, including visual modeling, rule engines, and runtime execution layers - Advantage

   

Personal skills

We offer

• Opportunity to design and develop complex integration solutions
• Stable permanent job contract
• Flexible working hours to help you keep the work-life balance and find time for your hobbies
• Partnership approach & communication respecting individual needs and employee development plan ideas
• Possibility to gain professional experience and learn from global industry experts
