Jobs Fullstack

Our client: US product company, an athletics management platform used by thousands of schools across the United States: rosters, eligibility, scheduling, officials assignment and payments. A mature product with real scale, now adding AI features to the core workflows.

You will own features end to end, across the stack, in a small team where what you ship reaches production the same week.

Format and time zone

Fully remote from Ukraine. The team is distributed across US time zones, with its core on US Central Time. We ask for a few core overlap hours daily, in practice from around 16:00-17:00 Kyiv time. Everything else is asynchronous and written by default, with a low meeting load.

What you'll do

• Build user-facing features in Node.js/Express and React with TypeScript, from spec to production
• Own the full slice: API design, database schema changes, rollout and the monitoring that follows
• Work AI-first every day: funded frontier models from Anthropic and OpenAI, agentic coding tools, and repo-level convention files so generated code follows the team's patterns. The tools are used hard, the output is reviewed by humans, and PRs say what was generated
• Bring your own practice to the team: custom skills, project conventions, prompts and workflows that make the whole team faster, not just you
• Raise engineering standards through code review, architectural patterns and targeted refactors
• Support what you ship on a light shared on-call rotation

Requirements:

• 5+ years shipping production software as a full-stack engineer
• Strong Node.js with Express (or NestJS) and React, both in TypeScript
• PostgreSQL: schema design, migrations, query optimisation
• Working knowledge of AWS (ECS/Lambda, Secrets Manager, CloudWatch) and CI/CD in GitHub Actions
• Daily, hands-on use of AI coding tools (Claude Code, Cursor, Copilot or similar). Not occasional autocomplete, but agentic workflows, custom skills that encode project conventions, and the judgement to tell genuinely good generated code from code that merely looks plausible
• Comfortable owning a feature alone, from database to UI
• English B2+ for daily written async communication

Nice to have

• Angular, for the parts of the platform built on it
• MCP servers, custom agent skills or other tooling you built around AI-assisted development
• React Native
• Domain experience in scheduling or logistics

• Actively use Agentic Coding tools (e.g., Claude Code, Codex, Cursor) to improve development workflows.
• Work with relational databases (MySQL and/or PostgreSQL) and in-memory storage/caching solutions (e.g., Redis, AWS ElastiCache).
• Understand the AWS ecosystem and basic DevOps practices.
• Apply knowledge of microservices, microfrontends, BFFs, and asynchronous communication systems (e.g., RabbitMQ, Apache Kafka, Amazon SQS).
• Think in terms of business and product impact, not only implementation.
• Demonstrate eagerness to learn and share knowledge with others.
• Show independence, ambition, and a strong ownership mindset.
• Thrive in small, fast-moving teams with frequent releases and quick iteration cycles.

We're an early-stage product company building an AI-powered analytics platform for the iGaming industry. Users get answers from their data in plain English — an LLM turns questions into validated SQL over a large data warehouse — alongside a set of analytics dashboards and data pipelines. It's live in production.

You'd be our first dedicated engineer, working directly with a technical founder (product) and an experienced CTO (architecture + code review) — with a real path to Tech Lead as the team grows. You won't be flying solo, and you'll help shape the architecture, not just maintain it.

What you'll do

• Build and ship features across the backend and the dashboard.
• Write correct, performant SQL against a large Postgres warehouse — the numbers drive real decisions.
• Extend the LLM→SQL pipeline and the analytics APIs behind the product.
• Own reliability, testing, and deploy stability as we scale.

• Maintain and extend the React / TypeScript front end.

   

Stack

• Backend: Python 3.12 + FastAPI (async, SQL-first with asyncpg — no ORM).
• Data: large Azure PostgreSQL warehouse (tens of millions of rows) + nightly aggregation pipelines.
• AI: Anthropic Claude (natural-language → SQL, agent workflows).
• Frontend: React 18 + TypeScript + Vite, shadcn/ui + Tailwind, TanStack Query, Recharts.
• Infra: Azure, Redis, Docker, GitHub Actions.

Note: the data-science/ML models are owned by the founder — you won't build or maintain those.

You'll thrive here if you have

• Strong SQL and relational-DB skills (Postgres a plus) — the single most important thing.
• Solid Python, ideally with an async framework (FastAPI).
• Good React + TypeScript.
• A correctness-first instinct for data, and the ability to pick up a fast-built codebase and make it solid.

• Comfort with cloud + CI/CD (Azure a plus) and Docker.

   

Nice to have

• LLM app experience (Anthropic/OpenAI, NL→SQL, RAG).
• Data engineering / BI / warehousing background.
• iGaming, fintech, or marketplace domain experience.

Why join

• A live, revenue-generating product — early enough to shape it.
• A clear growth path to Tech Lead.
• Modern stack: large data warehouse + production LLM pipeline + polished React app.
• Real support: a technical founder on product, an experienced CTO on engineering.

Senior Full-Stack Engineer, Platform and Compliance (Node.js / GCP)
| Remote | Part-time, 50% capacity: about four hours per weekday, worked during US business hours

Project makes secure mobile access simple. Retailers and grocers use our QR-based system to control access to restrooms, fitting rooms, and locked merchandise. A visitor scans a QR code on our signage, opens a lightweight web app in their browser (no app download, no account, no PII), and receives a one-time digital pass that opens the door. The platform maintains SOC 2 compliance and is live with national retail and grocery chains.

We are a small, senior, distributed team. You will be our primary engineer, working directly with our CTO and leadership. This is a part-time position at 50% capacity: roughly four hours each weekday, and those hours must fall within US business hours. Where you work is flexible; when you work is not. The role deliberately blends three things: product engineering, DevOps, and security compliance ownership. If you want narrow scope, this isn't the job. If you want to run the whole platform of a real product in the field, it is.

What you'll own

• Product engineering. Our stack is Node.js and Next.js: a multi-tenant web application on Google Cloud that generates and validates one-time access credentials, plus the services and databases behind it. You'll ship features, fix what's broken, and steadily improve the codebase.
• Platform and DevOps. The full GCP footprint: services, managed databases, IAM, secrets management, backups and tested restores, and cloud cost. CI/CD and release engineering with safe, reversible deploys (we use Bitbucket with a PR-based workflow).
• Reliability. Monitoring and alerting (Sentry for errors, BetterStack for uptime), incident response, and real root-cause discipline: no production changes before diagnosis, and postmortems that actually change things.
• Security and compliance leadership. You own our SOC 2 program end to end: controls, evidence collection, and audit cycles, managed in Drata with our external auditor. You will also lead our ISO 27001 certification, from gap analysis and ISMS scoping through risk assessment, controls, policies, and the certification audit.
• Provisioning tooling. Config-file-based device provisioning across our product SKUs, QR and signage file generation, and our internal sign-to-door linkage app. Part of this job is documenting and automating these workflows so they never depend on a single person.
• Hardware integration. Our credentials are validated by access-control hardware running our OEM partner's firmware (Wiegand protocol). You'll work with the partner's engineers on integration and field issues, define test cases, and represent engineering in those conversations.
• Data and support. Software-side support escalations and usage reporting (Looker Studio), in partnership with our operations team.

What we're looking for

• 5+ years building and running production web applications, including meaningful time as the owner of a system, not just a contributor to one.
• Expert-level Node.js and production experience with Next.js, plus solid relational database and API design skills.
• Hands-on GCP experience: deploying and operating services and managed databases, IAM, monitoring, and cost management. Strong AWS/Azure backgrounds welcome if you can come up to speed on GCP fast.
• Real DevOps chops: CI/CD pipelines, environment management, secrets handling, backup and restore you've actually tested.
• Compliance experience you've lived, not just read about: you've carried a SOC 2 program through at least one audit cycle (Drata, Vanta, or similar), and you've led or materially contributed to an ISO 27001 implementation, or are ready to lead one with auditor support.
• Operational maturity: you've been the person responsible when things broke. You care about root cause before fixes, reversible changes, and writing things down.
• Comfort in a small company: self-directed, pragmatic, and a strong written communicator. We run on Notion and Slack.
• Availability for about four hours per weekday, scheduled during US business hours. This is essential, not preferred: our team, customers, and hardware partner all operate on US time, and daily presence in our tools during those hours is part of the job.

Nice to have

• Physical access control, IoT, or other hardware-adjacent software experience (Wiegand, credential systems, embedded/firmware coordination).
• ISO 27001 Lead Implementer training or equivalent.
• Infrastructure-as-code experience (Terraform or similar).
• Looker Studio or similar BI tooling.
• Time as the sole, founding, or first engineer at a startup.

How we work

Low ceremony, high trust. A weekly product meeting keeps everyone aligned; the rest is written communication and focused work. You'll have direct access to a hands-on CTO, and your work will be visible to customers within weeks, not quarters.
