Responsibilities
As a Sr. Backend Fullstack Engineer you will:
* Own critical product areas end to end: architecture, implementation, testing, deployment, monitoring, and iteration.
* Operate as the DRI for your domain with minimal guidance, driving decisions and unblocking yourself.
* Focus on the Backend in Ruby on Rails while traversing the stack into LANDED’s Frontend web (Hotwire) and Mobile.
* Lead hands-on LLM and Generative AI feature development and productionization.
* Design and build systems and products that align with business objectives and real user needs.
* Be responsible for the upkeep, performance optimization, reliability, and scale-up of LANDED’s current product and processes.
* Uphold high engineering and security standards and continuously improve LANDED’s codebases and ways of working.
* Establish observability and operational excellence practices (metrics, logging, alerts, incident response).
* Troubleshoot and address bugs or issues swiftly and efficiently.
* Collaborate cross-functionally to shape specs, ship measurable outcomes, and learn from impact.
* Mentor teammates, give clear reviews, and help raise the engineering bar.
You’ll be a great fit if you:
* Have 6+ years of experience as a Backend or Full-stack Engineer delivering projects of varying complexity.
* Are highly proficient with Ruby on Rails and comfortable working across the stack when needed.
* Have experience working with JavaScript.
* Have strong experience with relational databases, mainly PostgreSQL, and ORM libraries like ActiveRecord, including performance tuning.
* Thrive in autonomy, prefer ownership over direction, and bring structure to ambiguous problems without hand holding.
* Like to ship code and test user-facing changes swiftly and rapidly, using CI/CD and automated testing.
* Learn quickly in new environments with a solutions-focused mindset.
* Communicate clearly and collaborate well in cross-functional settings.
Bonus points if you:
* Have commercial experience with React or React Native.
* Have experience with or are willing to learn Hotwire and Stimulus.
* Have experience in the SaaS or FinTech space, LLM development, and/or Applicant Tracking System or Human Resource Information System integrations.
* Have led projects end to end, influenced architecture, and mentored other engineers.
* Are comfortable with background jobs and caching in Rails (e.g., Sidekiq, Redis) and with cloud infrastructure and deployment tooling.
