Role Description Nooxit is looking for a Full Stack Engineer who wants to build things that matter — someone who's equally comfortable designing a clean API as they are shipping a polished frontend feature, and who genuinely cares about whether the AI behind it is actually getting things right. Our product makes critical financial decisions for enterprise customers, so accuracy isn't a nice-to-have — it's everything. We want someone who's obsessed with observability: - If the AI extracts the wrong line item, misclassifies a transaction, or drifts in confidence over time, you want to know about it before anyone else does. - You'll build the systems that measure, surface, and improve model performance — from evaluation pipelines and accuracy dashboards to real-time alerting on prediction quality. - You'll work across the stack to develop, improve, and scale cloud-native applications while ensuring we always have a clear, data-driven picture of how our AI is performing in the wild. - You'll have real ownership, creative freedom, and the opportunity to shape both the product and the engineering culture as we grow. Qualifications - Strong proficiency in Python and TypeScript - Solid experience with Docker, Git, and cloud-based development workflows - Familiarity with SQL databases (PostgreSQL preferred) - Experience with or willingness to work with: Pytest, CI/CD pipelines, Kubernetes, Terraform, Helm - Comfort working across backend and frontend — you don't need to be an expert in both, but you're curious and willing to learn - Experience with testing practices and a quality-first mindset - A genuine passion for AI accuracy and observability - Comfort with metrics and data analysis - Proactive, communicative, and comfortable working autonomously in a remote team Requirements - Previous experience in a startup or fast-moving environment (BONUS) - Hands-on experience building evaluation pipelines, accuracy benchmarks, or monitoring for ML/AI systems in production (BONUS) - Experience with observability tools and practices (e.g., Prometheus, Grafana, Datadog, OpenTelemetry, structured logging, distributed tracing) (BONUS) - Familiarity with ML metrics concepts — confusion matrices, F1 scores, calibration curves, data drift detection, A/B testing (BONUS) - Experience working at the intersection of engineering and data science (BONUS) - Interest in AI/ML applications or fintech (BONUS) - Experience mentoring other engineers or helping shape engineering processes (BONUS) Benefits - Fully remote — work from anywhere in the world - Flexible working hours — we care about output, not clocked hours - Competitive salary with room to grow as the company scales - An open, diverse, and international team that values collaboration and curiosity - The chance to work with renowned enterprise customers and help build what could become the next finance automation category leader - Real ownership and influence over the product and engineering direction

Role Description The Principal Backend Engineer is the most senior individual contributor on our backend engineering team — the person others go to when a problem is hard, a decision is consequential, or a system needs to be built right the first time. This is not a people-management role, but it is a leadership role: you set the technical direction for our backend systems, raise the engineering bar across teams, and solve problems that cut across products and disciplines. Our backend is built primarily on Ruby on Rails. You’ll own the architecture, standards, and long-term health of those systems while staying hands-on with production code. You’re also an engineer who has figured out how to get great results from AI tooling, and you bring that leverage to everything you do — and help the engineers around you do the same. You’ll report to the SVP of Technology and work closely with product, data, and platform teams. This is a high-ownership role for someone who leads through expertise and trust rather than title. In your first year, you've succeeded when: - The architecture is documented and actively owned. - The backend architecture roadmap is real and being executed. - The engineers around you are making harder technical decisions with more confidence — with or without you in the room. You must reside in one of these US states: AZ, CO, FL, GA, IL, IN, KY, MA, MD, MI, MN, NC, NV, OR, PA, RI, TX, VA, VT, WI, or one of these provinces in Canada: Ontario. Qualifications - 8+ years of professional software engineering experience, with demonstrated progression into senior technical leadership. - Deep expertise in backend engineering, with strong, current command of Ruby on Rails. - Proven experience designing and delivering large-scale, distributed systems that are maintainable, observable, and reliable in production. - A strong command of software design principles — SOLID, DRY, domain-driven design, event-driven architecture, and the like. - Experience leading technical design across multiple teams or product areas without direct authority. - A demonstrated AI-forward practice: you actively use AI tools to get strong results and have a clear point of view on where they help and where they don’t. - Excellent written and verbal communication — you can produce clear architecture docs, decision records, and technical specs, and explain them to engineers and non-engineers alike. - Comfort working in a remote, async-first environment with a high degree of ownership and autonomy. Requirements - Experience in a principal, staff, or architect-level role at a product-driven technology company. - Familiarity with cloud infrastructure, CI/CD pipelines, and Infrastructure/Platform practices (AWS preferred). - Experience with experimentation platforms (Optimizely, LaunchDarkly, VWO, or similar) and product analytics tools (Mixpanel, Amplitude). - A background in edtech, SaaS, or consumer-facing digital products. - A bachelor’s or advanced degree in Computer Science, Software Engineering, or a related field — though experience speaks louder. - A background in or genuine curiosity about the outdoors — our users are hunters, anglers, boaters, and snowmobilers. Benefits - We are a fully distributed company – unless specifically indicated in the job description, this is a work from home position. - Employer matched 401(k). - Medical/Dental/Vision insurance with generous employer contributions (including HSA). - Maternity and Paternity leave and benefits. - Three weeks of paid vacation, 12 paid holidays, a paid community service day, and a flexible work schedule. - Annual wellness allowance, as well as a paid mental health day once a year for when you need it. - Automatic WFH contribution to each paycheck. - Employee Assistance Program (EAP).
