It’s home to our Co-Found program, where ambitious founders take products from zero to market in months, not years. This is where you get hands-on, zero-to-scale experience you won’t find in a regular job.\n\nWe are a fast-scaling travel startup with strong product-market fit, a generational traveltech company looking to disturb this sleepy industry. We are two-sided: travelers get a consumer product that helps them plan and book trips, and advisors get a SaaS-style subscription with certification and qualified leads in the offer.\n\nWe’re looking for the first developers to join a fast-growing travel startup that’s already found strong product-market fit and is now ready to scale.\n\nThis is not a role for someone who wants to manage agencies, coordinate stakeholders, or spend weeks building presentations. We’re looking for a builder – someone who can design a schema for breakfast, build a sandbox environment for lunch, load test it before dinner, and wake up excited to get it ready for prod the upcoming week.\n\nYou’ll work directly with the founder and early team, own growth from day one, and help shape what the product looks like as the company scales. Work-life balance can look different in a fast-moving company that’s on a mission to make a real impact.\n\nAbout the role\n\nYou’ll lead the move of our platform onto AWS and own the infrastructure and backend foundations it runs on. A big part of this role is building bulletproof background processing: queues and workers that never lose state (since they are part of our payment system), recover cleanly from failure, and scale with demand. Our current stack is TypeScript, Supabase (PostgreSQL), and TanStack, with a PHP/Laravel backend migration planned to AWS.\n\nReady to apply?\n\nJump to the application form and start your journey with us.\n\nGet ready to\n\nLead the migration of our platform to AWS, from planning the architecture to executing the cutover with minimal downtime.\n\nOwn the migration of our PHP/Laravel backend to AWS, deciding what moves as-is and what gets re-architected along the way.\n\nDesign and build background processing for our payment flows: queues and workers that never lose state, handle retries and idempotency correctly, and recover cleanly from failure.\n\nMake sure every job and transaction is traceable and auditable, so nothing goes missing between systems.\n\nBuild infrastructure that scales with demand, including autoscaling workers, managing load spikes, and keeping costs under control as we grow.\n\nSet up infrastructure as code, CI/CD pipelines, and environments (dev, staging, prod) that let the team ship quickly and safely.\n\nPut monitoring, logging, and alerting in place so problems are caught early and diagnosed fast.\n\nOwn security and reliability across the infrastructure, including access control, secrets management, backups, and disaster recovery.\n\nStrengthen the backend foundations of our TypeScript, Supabase (PostgreSQL), and TanStack stack so it can support production scale.\n\nWork directly with the founder and early team on infrastructure decisions that affect the product, and set the standards future engineers will build on.\n\nRequirements\n\nStrong software engineering fundamentals, with deep experience in Platform / Cloud Engineering (AWS) and Backend Software Engineering (PHP, Laravel, PostgreSQL).\n\nDeep, hands-on AWS expertise, especially SQS (standard and FIFO, visibility timeouts, DLQs), S3 (lifecycle policies, access control, presigned URLs, event notifications), and related services such as Lambda, ECS/Fargate, IAM, EventBridge and CloudWatch.\n\nProduction experience with PHP and Laravel, including Laravel Queues, Horizon or equivalent, and designing backend services on PostgreSQL.\n\nProven track record building highly reliable worker and queue systems: retry strategies with exponential backoff, idempotent job design, exactly-once or effectively-once processing, dead-letter queues, and state handling that survives crashes, deploys and partial failures.\n\nExperience planning and delivering complex platform migrations with minimal downtime, ideally including moving from a managed platform such as Supabase to self-managed AWS infrastructure.\n\nStrong Infrastructure as Code experience with Terraform, AWS CDK or Pulumi, plus CI/CD pipeline design.\n\nStrong understanding of observability and operational excellence: metrics, logging, tracing, alerting and incident response, using tools such as Datadog.\n\nSolid understanding of modern authentication and identity concepts (OAuth2, OIDC, SAML) and cloud security best practices, including IAM least privilege and secrets management.\n\nComfortable in an agile, collaborative environment and communicating effectively with technical and non-technical stakeholders.\n\nExperience leading technical initiatives, influencing architectural decisions or providing technical leadership across teams.\n\nNice to have\n\nTypeScript experience is an advantage, as it is the team’s primary development language.\n\nCompany offers\n\nHealth insurance (after probation)\n\nOn-site physiotherapist\n\nOffice gym and fitness classes\n\n7 extra days off\n\n3 days off for weddings\n\nHybrid work\n\nFreedom to work 2 months from anywhere in the world\n\nPet-friendly office\n\nFresh breakfasts and hot lunches\n\nDrawers and fridges stocked with snacks and food\n\nRooftop and cellar events\n\n10 social clubs\n\nPublic transport card for Vilnius\n\nPerks.lt perks\n\n€1000 yearly budget for coaching, mentorship, training, conferences, online courses, subscriptions, books\n\nOpportunity to step in as a co-founder\n\n€1500 for every successful
