Principal Full Stack Engineer

Locations: Colombia only (remote) Come join us at Odisea Cultura and work with some of the most exciting start-ups in the US The Mission IdleX is redefining the semi-truck eAPU as an AI-driven, zero-idle, zero-maintenance system. We are moving beyond static gauges to a system that predicts range, monitors health via acoustics, and communicates in natural language. As our Principal Engineer, you will be the "superstar" architect responsible for the entire data journey—from hardware-adjacent telemetry to the cloud-based fleet portal. What You’ll Do Full-Stack Platform Ownership: Design and implement backend services that ingest, normalize, and persist high-volume telemetry using event-driven and MQTT-based pipelines. IoT & Device Lifecycle: Implement secure authentication and bi-directional communication for commands and diagnostics, designed for intermittent connectivity. AI-Native Backend: Integrate edge AI outputs (range prediction, health monitoring) into cloud services and surface them explainably in a Fleet Portal UI. Connectivity Orchestration: Architect robust MQTT communication protocols for data exchange between the eAPU and various external devices/cloud services. Technical Leadership: Act as the technical "right-hand" to the leadership team, making pragmatic trade-offs between speed, reliability, and simplicity. Technical Requirements Must-Haves (The Core): English: Spoken & Written English at a level C1 or better. Experience: 5+ years of full-stack engineering experience with clear ownership of production systems. Languages: Expert proficiency in Python and TypeScript . IoT & Messaging: Proven experience with MQTT , pub/sub patterns, and device telemetry pipelines. Backend & Cloud: Strong experience with AWS (or other clouds), cloud-native microservices, and event-driven architectures. Data Models: Experience with time-series data, relational databases, and telemetry-heavy models. Distributed Systems: Strong understanding of data consistency, failure modes, and scalable backend platforms. Industry Context: Experience with hardware‑adjacent systems (smart homes, automotive, or mobile IoT) where data is harvested and shipped to the cloud. Hardware Awareness: Ability to reason about and manage specifics including: Main SoC: Dual-core RISC‑V (up to 400 MHz). Sensors: 3‑axis Gyro (IMU), GNSS, and Microphone headers. Memory/IO: SRAM, Tightly Coupled Memory (TCM), Ethernet, eSIM/LTE, and USB Camera interfaces. Nice‑to‑Haves (The "Unicorn" Traits) Languages: C and C++ . Embedded & UI: Knowledge of ESP‑IDF (Espressif) and LVGL for front-end screen development. Rapid Prototyping: Experience with EEZ Studio for UI prototyping. Specialized Protocols: Experience with J1939/CAN or NMEA 2000. Embedded AI: Experience with neural network math, LSTM reasoning, and operationalizing AI/ML outputs (federated learning, shadow models). How You Work AI-Forward: You must be "AI positive" and a superstar at using AI tools to accomplish tasks and increase efficiency. Startup Mindset: You are comfortable with ambiguity and willing to flex your hours to collaborate with global vendors (Australia/China) when necessary. Written Thinking: You capture decisions, assumptions, and system behavior in writing to create shared understanding. Tinkerer’s Soul: You aren't just "textbook"—you likely tinker at home with chipsets or hardware because you find it fun.
