About the Client

The client is an American SaaS company in marketing analytics. Its platform helps e-commerce brands understand which ad spend truly drives revenue. It collects tracking data, combines it with data from major ad platforms, and uses ML modeling to turn it into reporting.

The company’s customers spend millions per month on advertising, so data volumes are large and business decisions depend on data accuracy.

About the Project

There are several projects in progress:

• Conversion API (main project): reprocessing tracking signals and delivering them to ad-platform APIs in real time. Each platform’s API works differently and has its own quirks, so integrations require careful work. Stack: Python streaming, Google Pub/Sub, Shopify JS tracking.
• Mobile attribution SDK (greenfield): a new SDK for JavaScript and iOS.
• Analytics data pipelines: pipelines built as part of the SaaS product, not internal BI.
• Full-stack product development: application features and integrations.

Requirements:

• Senior or Staff level, 7+ years of commercial experience in software engineering

• Experience with GCP and BigQuery
• Track record of building customer-facing products, not just internal tools or dashboards 
• Ability to design engineering abstractions and discuss architectural decisions with the team, explaining trade-offs
• Fluent English (C1) for daily communication with the US team: syncs, technical discussions and written communication

Nice-to-have:

• Experience with e-commerce and tracking analytics

• Experience with Google Pub/Sub and Airflow

   

Responsibilities:

• Work as a full-stack engineer on product features and integrations across frontend and backend
• Develop application features as part of full-stack product development

Requirements

• 7+ years of experience
• Sole engineer or engineering lead on a live production SaaS product, with end-to-end ownership of architecture, infrastructure and deployments
• Strong TypeScript and Node.js (Express)
• Solid PostgreSQL experience (schema design, query optimization)
• Modern frontend experience. Svelte is ideal, but strong React is fine if you can pick up Svelte quickly
• Hands-on CI/CD, GitHub workflows, production monitoring and troubleshooting
• Able to make decisions independently with minimal supervision
• English B2+

Nice to have

• Accounting or financial API integrations (QuickBooks, Xero, etc.)

Who we are

We’re a fast-growing telehealth product launched in 2025, focused on the US market. Our platform connects patients with doctors for weight-loss treatment, prescriptions, and insurance-covered telehealth visits.

We work in a HIPAA-conscious environment where reliability, security, and responsible handling of sensitive information are essential. Our user base is growing quickly, and our team is remote-first across multiple countries.

Role Overview

We're looking for a Senior Full-Stack Engineer to help build and scale the applications our patients and internal teams use every day. You'll work across the stack using React, Next.js, Node.js, and TypeScript, partnering closely with product managers, designers, QA engineers, and fellow developers to turn ideas into reliable, production-ready features.

This isn't a frontend role with occasional backend work, or vice versa. We expect you to own features end-to-end, from designing APIs and implementing backend services to building intuitive, high-performance user interfaces. You'll bring strong technical judgment to the table, knowing when a solution won't scale, identifying potential bottlenecks early, and writing code that others can confidently build upon.

We expect engineers to influence technical decisions and system architecture, challenge assumptions when appropriate, and do more than simply implement predefined tickets.

What matters to us just as much as the tech stack is how you approach your work. We're looking for someone who takes ownership, follows through on commitments, and speaks up when something doesn't look right instead of waiting to be told. Real patients use what we build, and that tends to attract engineers who genuinely care about getting it right.

This role is a great fit for a senior engineer who enjoys building products across the stack, cares deeply about UX, performance, reliability, maintainability, and protecting sensitive data through secure design and strong encryption practices, and treats AI-assisted development tools as a normal part of the daily workflow, not a novelty.

What you'll do

• Build and maintain patient-facing and internal applications using React, Next.js, Node.js, and TypeScript, delivering complete features across both the frontend and backend.
• Design, build, and evolve backend APIs and services, integrating with our commerce platform, Python-based microservices, and cloud infrastructure.
• Release in small, reversible increments backed by CI/CD, automated tests, and observability, rather than big-bang launches.
• Favor pragmatic, well-balanced solutions over gold-plating. Ship something robust and useful first, then iterate based on real feedback.
• Own what you ship end-to-end. Quality, reliability, performance, security, and operational readiness don't stop at merge.
• Bake security, privacy, and HIPAA-conscious data handling into every change, not as an afterthought.
• Turn Figma designs into responsive, accessible user interfaces with close attention to UX, accessibility, and Core Web Vitals.
• Build secure and scalable media delivery and asynchronous processing workflows.
• Collaborate with Product, Design, QA, and other engineers to validate solutions and prioritize what delivers the most value for patients.

• Take code reviews seriously, both giving and receiving feedback, and actively share knowledge as the stack evolves.

   

Success in this role looks like

• Performance, reliability, and maintainability remain first-class concerns across both frontend and backend services.
• Deployments stay low-risk and reversible through small, incremental releases rather than big-bang launches.
• Production issues are rare, and when they do occur, they're easy to diagnose and resolve.
• Sensitive data flows are handled correctly, with no PHI or security surprises.

• Your code reviews and technical decisions visibly raise the engineering bar across the team.

   

Team & Culture

• Direct, no-nonsense communication culture; disagreeing with your lead is normal and encouraged.
• Scrum/Kanban hybrid workflow with mandatory code reviews.

• A team that genuinely values engineering quality and initiative

   

Hiring Process

We aim to complete the hiring process within approximately two weeks.

1. Introductory call with a recruiter (30 minutes)
2. Technical interview with the Team Lead and Tech Lead (90 minutes)
3. Final interview with the Team Lead and CTO (45-60 minutes)

Benefits

• Competitive compensation based on your experience and skills.
• Flexible schedule and remote work options.
• 20 working days of paid vacation per year.
• 5 paid sick days per year.

• Opportunity to build a product used daily by thousands of patients in the US healthcare market.
• Company-provided equipment.

• Paid AI tooling subscriptions (Claude Code, GitHub Copilot, Cursor, or similar).

   

Job Requirements

Must have:

• 5+ years of professional software engineering experience building production applications with React, Next.js, Node.js, and TypeScript.
• Experience designing and implementing REST and/or GraphQL APIs, authentication flows, and backend services using Node.js and TypeScript.
• Experience designing secure authentication and authorization flows (JWT, OAuth, session-based authentication, etc.).
• Experience designing data models and working with relational and/or NoSQL databases.
• Experience with state management approaches.
• Solid understanding of web performance, accessibility (WCAG), and SEO considerations in a Next.js environment.
• Experience working with AWS services such as S3, CloudFront, Lambda, or similar cloud infrastructure.
• Hands-on production experience building and evolving software over time. You understand what breaks in production, how to debug it, and how your technical decisions affect the product beyond the initial release.
• Regular hands-on use of AI-assisted development tools (Claude Code, Codex, GitHub Copilot, Cursor, or similar) as part of your daily workflow.
• Strong ownership mindset. You understand the business context, make pragmatic technical decisions, and ship reliable solutions.

• Upper-Intermediate (B2) English or higher, with the ability to communicate effectively in written and spoken technical discussions.

   

Bonus points:

• A degree in Computer Science or a related field is a plus.
• Experience in healthcare, telehealth, or other regulated domains (e.g. HIPAA) is a strong plus.
• Experience building or working with a design system or component library.
• Experience with Stripe or other payment and checkout flows.

• Bring existing projects to a reliable state, so they work in production and not only in a demo
• Secure our projects: authentication and roles, storage of data and passwords, API protection, pre-release security checks, protection of clients' personal data under GDPR
• Deploy and maintain projects: Linux, Docker, Git, CI/CD, backups, monitoring, updates, access management
• Investigate incidents: find the root cause, restore service and prevent a repeat
• Write a plan and timeline before each task and send short daily, weekly and monthly reports

• Document what you build (service design, release and recovery procedures) so no system lives in one person's head

   

Requirements

• Fluent Ukrainian or Russian (required), as it's the language of the team; English for documentation
• 2–3+ years of commercial development (backend or full-stack), with at least one project you took to real users yourself
• Python or TypeScript (Node.js), PostgreSQL, APIs and integrations
• Docker, Linux, Git, basic CI/CD: you deploy your own projects to a server
• Security basics: no secrets in code, roles and access control, HTTPS, backups, no client data in logs
• At least one year of daily work with AI tools (Claude Code, Cursor or similar) and the ability to verify AI-generated code instead of pasting it blindly
• Ownership and transparency: you write your own plans and flag risks and mistakes immediately
• Ability to explain to a non-technical person what is done, what isn't and why

Nice to have

• Startup experience or your own launched projects
• OWASP Top 10, security checks in CI, practical GDPR experience
