Senior FullStack Software Engineer
Arionkoder
Role Description
We are looking for a Senior Full-Stack Engineer to design, build, and ship features end-to-end across one of our core product teams — from the interface a user touches, through the API, down to the data. You own meaningful parts of the product front to back:
- Shape the approach with your team.
- Build both the UI and the services behind it.
- Test them and run them in production.
This is a hands-on role: most of your day is spent writing, reviewing, and debugging real code across the stack, with the autonomy to make sound technical decisions and the judgment to know which ones to raise.
You care about more than making it work. You think about:
- Edge cases
- Failure modes
- Performance — both on the server and as the user perceives it
- Accessibility
- The engineers who'll read your code next
You collaborate closely with product managers, QA, and fellow engineers to turn ambiguous goals into reliable software, and you push back early when requirements don't add up. You bring an AI-first working style — using AI tooling daily to move faster across design, coding, and review — with the judgment to catch where its output falls short.
This is not a role for someone who lives on only one side of the stack. We need an engineer who's genuinely comfortable building and owning a feature from the component to the database, takes it from ambiguous intent to shipped, reliable software, and raises the bar for the team around them.
Qualifications
- 5+ years of professional software engineering experience building and operating production systems, working across both frontend and backend.
- Strong fluency in JavaScript/TypeScript and Python; comfortable owning non-trivial code in both.
- Production experience with a modern framework (React, Vue, or similar) in TypeScript.
- Hands-on experience building services on AWS — using core compute, data, and identity services.
- Comfortable with modern CI/CD and Git workflows.
- Strong production instincts: writes testable code, handles failure deliberately, and can debug and profile a live system.
- Reads and works within an existing architecture.
- AI-first working style: hands-on daily use of AI tooling with the judgment to verify its output.
- Senior judgment and autonomy: takes ambiguous requirements to ship software with minimal hand-holding.
- Advanced English; comfortable in a fully remote, distributed team.
Requirements
- Frontend depth: working grasp of responsive layout, accessibility, and browser performance.
- Backend depth: building services and APIs (REST/GraphQL or event-driven) with solid data modeling across relational and non-relational stores.
- Experience integrating with multiple third-party platforms in production.
- Exposure to Infrastructure as Code (Terraform, CloudFormation/CDK, or Pulumi).
- Experience working in multi-tenant or enterprise-facing products with real security and data-residency constraints.
- Familiarity with observability tooling (Datadog, Grafana, Sentry, or similar).
- Experience mentoring engineers or leading the implementation of a sizable feature.
Benefits
- Monthly USD Service Fee
- 20 business days of paid Agreed Time Off—Annual + 6 Local Holidays
- Caregiver Time Off
- A dynamic remote work culture. You can work from anywhere!
- An entrepreneurial environment.
