Senior Full-Stack Developer
About The Position
Automat-it is an all-in AWS Premier Partner and Managed Services Provider specializing in the startup ecosystem. With over 800 customers and 500+ AWS certifications, Automat-it brings hands-on expertise in AI, DevOps, and FinOps to empower fast-paced startups to grow, deliver & win. Our customers save significant time-to-market and optimize their cloud performance and costs.
We work across EMEA and the US, fueling innovation and solving complex challenges daily. Join us to grow your skills, shape bold ideas, and help build the future of tech.
We are looking for a Senior Full Stack Developer to join our dynamic R&D Team, where you will own high-scale features end-to-end across our FinOps platform and AWS billing engine โ contributing directly to our mission of empowering fast-paced startups.
This is not a traditional coding role. You will generate the vast majority of your production code with AI, and your value comes from the deep technical judgment you apply on top of it: guiding the model, critiquing its output, and shipping solutions that are high-quality, maintainable, and future-proof. We're looking for a senior engineer who is excited that the craft of software is changing - and wants to operate at the frontier of it.
You will work with: Node.js/TypeScript (NestJS, Fastify, Prisma ORM) + React (TanStack, TipTap, Material UI, Untitled UI) + PostgreSQL.
๐ Work location - Remote Ukraine
Key Responsibilities
- Own features end-to-end โ from vague stakeholder ask to production deployment, including discovery, design, implementation, testing, rollout, and iteration.
- Refine requirements proactively using the Value, Usability, Feasibility, Viability (VUFV) framework. Push back on weak requirements, propose better solutions than the one originally requested, and keep a tight feedback loop with stakeholders.
- Generate your code with AI (We provide Claude Opus 4.7 in Cursor). Your job is to direct the model, review its output with a senior engineer's eye, and take full ownership of what ships โ including architecture, performance, security, and long-term maintainability.
- Continuously level up your AI workflow. Stay current with new models, tools, and techniques, and bring the best of them into the team.
- Solve deep technical problems across FinOps processes and AWS billing calculations.
- Write scalable, maintainable, well-tested, and well-documented code. Create and maintain system design and implementation docs.
- Implement and support unit tests as a first-class part of delivery.
Requirements
- 5+ years of experience as a Full Stack Developer shipping production systems.
- Deep expertise in the TypeScript full-stack ecosystem โ specifically NestJS and React โ and experience with microservices architectures.
- Strong experience with Prisma ORM + PostgreSQL.
- Proven ability to translate complex, ambiguous business requirements into concrete technical specs and actionable work โ and to challenge requirements when there's a better solution.
- AI-first mindset. You already default to AI for code generation, and you have the technical depth to guide it rather than be guided by it. You understand every line the model produces and can explain why it's the right (or wrong) solution. This is explicitly not a "prompt engineer" role โ it's a senior engineering role where AI is the primary authoring tool.
- Strong debugging skills and a serious approach to unit testing.
- Excellent problem-solving skills and a bias toward action and unblocking.
- Fluent written and verbal English.
Nice to have:
- Experience with vector databases.
- Experience with monorepo tooling (Turborepo, Nx).
- Familiarity with AWS services, especially AWS Cost Explorer and AWS Cognito.
- Experience with financial dashboards or data-heavy UI.
- Strapi Framework experience.
- Experience with Material UI at scale.
- Strong SQL knowledge.
- Experience with Puppeteer / Playwright.
- Experience with Fastify.
Why join Automat-it?
- Professional training and certifications covered by the company (AWS, FinOps, Kubernetes, etc.)
- International work environment
- Referral program โ enjoy cooperation with your colleagues and get a bonus
- Company events and social gatherings (happy hours, team events, knowledge sharing, etc.)
- Wellbeing and professional coaching
- English classes
- Soft skills training
Country-specific benefits will be discussed during the hiring process.
Automat-it is committed to fostering a workplace that promotes equal opportunities for all and believes that a diverse workforce is crucial to our success. Our recruitment decisions are based on your experience and skills, recognizing the value you bring to our team.
