Jobs Fullstack

Senior Full-Stack Engineer

Lidgen · Remote · Full-Time

About Lidgen

Lidgen (lidgen.io) is a fast-moving Sales Tech startup building cold outreach and lead generation infrastructure for B2B companies. We operate in the B2B lead generation and cold outreach space, building infrastructure used by sales teams to run outbound campaigns at scale. We move fast, we build smart, and we hold ourselves to a high standard. You'll work directly with the founder with real ownership and real impact on a product actively used by clients.

The Role

We need a senior full-stack engineer who can own the technical side of the company end to end — not just write code, but make proper tech decisions, manage infrastructure, and build internal automation that keeps operations running smoothly.

You'll start by blending into the existing setup, then progressively take full ownership of everything technical — with the goal of becoming the sole technical lead at Lidgen.

This isn't a ticket-execution job. We need someone with judgment, not just execution speed.

What You'll Own

• Full-stack codebase — features, architecture, code quality
• Database and auth layer — schema design, performance, security
• Cloud infrastructure — deployments, VM management, monitoring
• Automation workflows — lead enrichment, outreach launches, internal ops
• Internal tooling — AI-powered tools that reduce manual work
• API integrations — our GTM tool ecosystem

Core Tech Stack

• Next.js 16, React, TypeScript, TailwindCSS
• Supabase (PostgreSQL)
• Google Cloud Platform (GCP)
• n8n running on Docker (GCP VM)
• GitHub + GitHub Actions (CI/CD)
• Claude Code in VSCode for AI-assisted development
• Slack for daily communication (Israel business hours, UTC+3 — same timezone as Ukraine)

Requirements

Must Have

• 3–4+ years with Next.js, React, and TypeScript
• Solid experience with TailwindCSS
• Experience with Supabase or PostgreSQL
• Comfortable owning cloud infrastructure (GCP or similar)
• Strong API integration experience
• Available during Israel business hours (IST / UTC+3) on Slack
• Able to make independent technical decisions without hand-holding
• Professional English communication

Good to Have

• Experience with n8n, Make, or similar automation tools
• Familiarity with cold outreach platforms: Smartlead, Instantly, Clay
• Docker and containerized deployment experience
• Experience building internal back-office tooling
• Familiarity with AI-assisted development tools (Claude Code, Cursor, etc.)

Compensation

Starting: $1,500/month for the first month (trial period)

Growth path: $2,000–$2,500/month upon successful completion of the trial. As you take on full technical ownership and replace the need for additional part-time developers, compensation grows accordingly.

This is a real long-term role with real upside — not a short-term contract.

About Us

Smirnov Labs is a fast-growing engineering company founded by an ex-Googler. We help product teams launch and scale quickly by leveraging modern technology and AI-assisted development.

Our projects are diverse — we partner with clients at the earliest stages and own the technical delivery end-to-end.

We're a small, senior-heavy team where every engineer has real impact. No bureaucracy, no hand-holding — just sharp people shipping fast.

What You'll Do
 

• Own features end-to-end: from architecture and implementation to deployment and support
• Build and ship web applications using React, Next.js, Node.js, and TypeScript
• Design and maintain APIs, services, and data layers (MongoDB, Redis)
• Deploy and operate services on AWS with Docker
• Communicate with the CTO and client-side engineering team directly — no layers in between
• Use AI-assisted development tools (Claude, Cursor, GitHub Copilot) as part of your daily workflow
• Work across diverse projects — different domains, different challenges

What We're Looking For
 

• 5+ years of professional full-stack development experience
  Strong TypeScript skills on both frontend and backend
• Solid hands-on experience with React, Next.js, and Node.js
• Production experience with MongoDB, Redis, AWS, Docker
• Comfort working in US timezone (overlapping working hours required)
• Upper-Intermediate or higher English
• Ability to own and drive features independently with minimal supervision
• Go experience is a plus

What We Offer

• Competitive salary above market average
• Fully remote work
• Flat structure — work closely with the CTO, no middle management
• Diverse and technically challenging projects
• Modern AI-powered development workflow
• Small team culture — your voice matters, your code ships
• Paid vacation and sick leave
• Flexible schedule within US timezone overlap
• Professional and career growth through real ownership, not courses and certificates
   

How to Apply

Send your CV with a brief note about a project you're most proud of.

About the Role

We are building an agentic document-processing platform that autonomously extracts, validates, and routes financial documents through complex approval workflows - without manual intervention. The system combines LLM orchestration, MCP (Model Context Protocol) servers, and enterprise API integrations into a single AI-driven pipeline.

We are looking for a Junior Full-Stack Developer to join a small senior team. You will work on real features - backend services, frontend components, database queries - and gain structured mentorship on a production AI product. No prior AI or LLM experience required.

This is a learning role with clear growth expectations. Within 12–18 months, you are expected to reach an independent Mid-level engineer on the full stack, including the AI orchestration layer.

Core: JavaScript/TypeScript (async, basic OOP), React (hooks, components), SQL (queries + indexes), Git, HTTP/REST, English B1+.

Plus: any backend framework (NestJS/FastAPI), deeper TypeScript, Docker, PostgreSQL; bonus/growth — LLM APIs, MCP/agents, React Query/Zustand, OpenTelemetry.

What You’ll Work On

Backend Development

• Build and maintain REST API endpoints using NestJS (Node.js / TypeScript) or FastAPI (Python)
• Write and optimize PostgreSQL queries, design simple schema additions, run migrations
• Add unit and integration tests; fix bugs identified in code review
• Integrate third-party REST APIs under senior guidance

Frontend Development

• Build React 18 + TypeScript components for document dashboards and approval workflows
• Connect UI to live backend APIs; replace mock data, handle loading and error states
• Work with Tailwind CSS and shadcn/ui component library
• Implement real-time status updates via Server-Sent Events (SSE)

AI Components (Mentored)

• Learn how the MCP server works: tools, context management, structured outputs
• Make calls to LLM APIs (OpenAI, Anthropic) using existing patterns; extend prompt templates
• Understand document extraction pipeline and help build UI for reviewing AI decisions
• Gradually take on AI-adjacent tasks as confidence grows

Infrastructure & Quality

• Work with Docker and docker-compose for local development
• Create and update GitHub Actions workflows for simple CI tasks

• Follow code review feedback and improve over time
   

   

What We’re Looking For

Beyond technical foundation, these qualities define the right person for this role:

Coachability

You take feedback seriously, apply it, and don’t repeat the same mistake twice. Code review is a learning tool, not criticism.

Curiosity

You investigate before asking. When you don’t know something, you try first, document what you tried, and then ask a specific question.

Ownership

You don’t drop tasks because they got unclear. You ask the right question, unblock yourself, and follow through to done.

Honest communication.

You say “I don’t know” when you don’t know. You flag blockers early rather than going silent for days. Async first -written updates matter.

We're a boutique software company building custom ERP systems for clients across healthcare, food manufacturing, fintech, and e-commerce. Our solutions help businesses streamline complex processes — and we build them with care, using modern technologies and close collaboration with clients.

As we take on more projects at different stages, we're looking for a developer who can step into an active team, get up to speed quickly, and start making a real contribution early on. If you're someone who adapts well to new contexts — whether it's a different codebase, domain, or team dynamic — this could be a great fit.

Tech stack

• .NET Core
• EF Core
• MSSQL
• Angular
• DevExtreme
• Cloud platforms

Who we're looking for

• Solid hands-on experience with .NET Core and Angular (6 years of experience)
• Experience working on ERP or business management systems
• Ability to onboard quickly and contribute meaningfully from early on
• Good communication in English (B2 or above)

Our client is an AdTech SaaS built on Shopify that helps e-commerce businesses run ads on Meta and Google. The product is evolving from a simple setup tool into a full AI-driven solution: it analyzes a store, identifies the best product opportunities, generates creatives, launches campaigns, and optimizes them automatically. The merchant sets a target ROAS — the system handles the rest.

They are looking for a Senior Engineer who can take real ownership of the product and help deliver the next stage of growth.

What you’ll own

In the first months, you’ll dive deep into the existing platform: stabilizing, maintaining, and building context. Then you’ll move into:

• AI-native experience: building store intelligence that analyzes merchant data, scores products by predicted ROAS, and drives campaign decisions automatically
• Deep Shopify integration: ensuring the product lives where merchants already work (Shopify admin, Sidekick, Flow), not as a separate tool
• Platform reliability & UX improvements: improving onboarding, ROAS optimization, and performance transparency

• Quality at every stage: owning QA as part of delivery — writing specs with acceptance criteria, critically reviewing AI-generated code, and ensuring features are tested before release

   

How the team works

The team follows an AI-assisted development approach:
spec → generate → review → refine → ship

You don’t need to write every line manually — but you do need to:

• write clear specs
• review code confidently
• maintain a high quality bar

You’ll work directly with the founders — no PM layer, no excessive processes.

This role is for you if:

• You have 5+ years of production experience with Python and React
• You have hands-on experience with AWS (EC2, RDS, S3, Lambda or similar)
• You’re comfortable owning the full stack (frontend, backend, infrastructure)
• You’ve worked with Shopify API, Meta Marketing API, or Google Ads API
• You’re used to being the primary engineer and making architectural decisions
• You can balance support and feature development
• You’ve used AI coding tools (Cursor, Claude Code, Copilot) and understand their strengths and limitations

• You treat QA as part of shipping (tests, code reviews, validation before release)

   

Nice to have

• Experience building or maintaining Shopify apps
• Familiarity with LLM APIs (OpenAI, Gemini)
• Background in AdTech or performance marketing

What our client offers

• Real equity — joining as a key engineer at a pivotal stage
• Ownership over architecture and decisions
• Fully remote, flexible schedule
• Competitive salary
• Paid vacation
