We need someone who can move fluidly between system design, backend implementation, frontend product surfaces, and production reliability — and who knows when to keep things simple instead of overengineering.What you’ll doDesign and build core backend systems in PythonShip customer-facing product features in React and TypeScriptMake key architecture decisions across edge, cloud, data model, APIs, and UIBuild reliable systems for telemetry ingestion, incident generation, and site-level intelligenceOwn features end to end, from schema and backend logic through UI and production rolloutHelp create a trustworthy product that explains what is broken, where, why, and what to do nextWork closely with founders to translate ambiguous product ideas into simple, durable systemsContribute to AI-powered product capabilities where they create real value, while staying pragmatic about what should be deterministic vs model-drivenWhat success looks likeYou make strong architecture decisions without adding unnecessary complexityYou ship meaningful product features independently across backend and frontendYou build systems that are reliable in production, not just impressive in demosYou create clean interfaces between components without prematurely abstracting everythingYou improve product trust by focusing on correctness, observability, resilience, and maintainabilityYou help us build a platform that can run reliably in the field and scale into a real productWhat we’re looking for8–12 years of software engineering experienceExperience in a Series A or similarly fast-moving startup environmentStrong backend engineering skills in PythonStrong frontend engineering skills in React and TypeScriptStrong experience designing and shipping production systems on AWSProven ability to ship reliable, complex product features end to endStrong solutions architecture judgmentComfort working across backend, frontend, infrastructure, data, and productHigh ownership, strong product sense, and the ability to thrive in ambiguityA bias toward practical decisions, fast iteration, and durable executionStrongly preferredDjango or similar Python web frameworksReal-time application patterns such as WebSocketsGraphQL APIsElasticsearch / OpenSearchExperience building telemetry, observability, workflow, infrastructure, or edge/cloud productsExperience with event-driven systems, distributed systems, or reliability-sensitive softwareExperience building products that combine deterministic logic with AI-assisted workflowsFamiliarity with modern AI tooling such as AI SDKs, LangChain, or LangGraphNice to haveExperience with networking, wireless, telecom, or edge devicesExperience with ingestion pipelines, schema/versioning, or time-series/event dataExperience with incident workflows, root-cause analysis, or evidence-driven UXExperience operating in small teams where speed, tradeoff quality, and ownership matterHow we think about engineeringWe care a lot about architecture quality, but we are not interested in architecture theater. The product has to be reliable in real environments. That means building systems that can tolerate outages, preserve data, recover cleanly, and produce trustworthy outcomes. It also means being disciplined about sequencing: building the right foundations first, shipping hardcoded logic before generic engines, and favoring correctness over cleverness. Reliability, explainability, and end-to-end product quality matter more to us than trendy abstractions.Our stackOur current and target...
