We are looking for a Senior Full Stack Engineer to join a fast-growing, AI-native startup that is rebuilding the software behind defence, aerospace and industrial supply chains. This is a founding-engineer-style role: you will own features end to end instead of picking up tickets. You will work closely with the founders, Deployment Strategists and other senior engineers to turn messy, manual workflows into semi-autonomous processes. You will start in Warsaw with the team, and the plan is to relocate to the US (San Francisco) within about six months, with visa sponsorship and relocation fully covered. This role suits a builder with strong full-stack skills, a passion for shipping and a real wish to move to the US and grow with an early-stage company. Success here means shipping useful, clean and maintainable code that delivers real value to customers.

It pairs the platform with forward-deployed engineers who work on-site with customers until their toughest operational problems are solved. The startup is backed by a top accelerator, has 7-figure ARR and is scaling quickly across defence, aerospace and industrial sectors.

You have:

• Strong, genuinely full-stack experience: TypeScript/JavaScript, React/Next.js and a backend in Node.js or Python
• Solid experience with PostgreSQL and SQL
• A strong track record that shows engineering excellence, for example: a top technical university, a reputable software house or product company, an elite internship, competitive programming or hackathon results, or past founder experience
• Builder mindset: side projects, open-source contributions, hackathons or 0-to-1 ownership
• Comfort with autonomy, ambiguity and a fast-paced, demanding startup environment
• Clear communication: you can explain and defend your ideas, set reliable deadlines and meet them
• Customer-focused approach: you see code as a way to deliver value and you own your work end to end
• Readiness to relocate to the US within about six months of starting
• Fluent English

Nice to have:

• Experience with complex integrations, data ingestion pipelines or ERP systems
• Experience with Svelte

Key responsibilities: 

• Service Development: Design, build and maintain secure, scalable backend services for authentication, authorisation, identity and personalisation, delivering high-quality, production-ready code. 
• Epic Tech Lead: Take on tech lead responsibilities for assigned epics: shaping the technical approach, breaking the work down and steering it through to delivery. 
• Quality and Testing: Write and maintain unit, integration and automated tests, and give constructive code reviews to keep engineering standards high. 
• Operational Excellence: Integrate services with monitoring and observability tooling, and take part in in-hours production support and incident response. Any out-of-hours support is arranged separately. 
• Prioritisation and Flow: Work to the priorities agreed with the team, and flag work that is poorly broken down or blocking delivery, proposing a better approach before picking up new work. 
• Collaboration and Knowledge Sharing: Work with architects, product and technical leads to turn requirements into implementable solutions, and support less experienced engineers through pairing, code reviews and knowledge sharing. 
• Agile Delivery: Work within an agile, multidisciplinary team to plan, develop and deliver product increments iteratively. 

Qualifications: 

• Backend Proficiency: Over 5 years of production experience building scalable distributed systems and backend services with TypeScript or JavaScript. 
• AWS Serverless: Over 2 years of experience with AWS serverless architecture, including Lambda, API Gateway, CDK and CloudFormation. 
• Test-Driven Development: Strong experience with TDD and broader testing and quality practices. 
• CI/CD and Operations: Experience implementing CI/CD pipelines and addressing operational concerns: monitoring, performance testing, scalability, availability, resilience and security. 
• Technical Leadership: Experience as technical lead on at least one medium or large piece of work (3+ months). 
• Nice to Have: Practical experience with OAuth 2.0, OpenID Connect and customer identity and access management (CIAM); Java; CloudWatch or Grafana; DynamoDB, Kinesis, ALB/WAF Node.js.
