About the role

  • Provide technical leadership for development and engineering teams (cloud, embedded/firmware, networking, data), ensuring best practices, quality, and predictable delivery;
  • Define and evolve end-to-end IoT solution architecture: device → gateway → connectivity (4G/5G, NB‑IoT, LTE‑M) → platform/ingestion → data lake → APIs/front-ends;
  • Select and standardize stacks, frameworks, and managed cloud services (e.g., AWS IoT, Azure IoT, GCP IoT, Kafka, time-series DBs), balancing cost, security, performance, and time-to-market;
  • Orchestrate the technical roadmap, prioritizing debt, scalability, observability, SRE, and test/CI‑CD automation;
  • Ensure security by design: device identity, PKI/certificates, TLS, hardening, secure OTA, network segmentation, key management and compliance (LGPD, ISO 27001);
  • Lead architecture reviews, code reviews and experiments (PoCs) to validate technologies, components and vendors;
  • Work with business, product and pre-sales teams to translate functional and non-functional requirements into clear, feasible technical solutions;
  • Define SLAs/SLOs, implement end-to-end monitoring (device telemetry, connectivity, platform, APIs) and respond to critical incidents;
  • Coordinate integrations with partners/ecosystem (OEMs, modules/Cat‑M/NB, eSIM platforms, device management platforms) and with internal systems (BSS/OSS);
  • Support cost management (FinOps) and optimization of cloud and connectivity consumption;
  • Develop the team: mentoring, career paths, dissemination of best practices and engineering culture;
  • Document architectural decisions (ADRs), standards and operational runbooks;
  • Participate in technical committees and innovation forums, bringing trends (5G SA, edge, eUICC/eSIM, AI at the edge).

Requirements

  • Degree in Engineering, Computer Science, Telecommunications or related fields;
  • Strong experience (5–8+ years) in software/systems engineering and 2–3+ years as a Technical Lead/Architect;
  • Proven experience with IoT production projects (E2E: device → connectivity → cloud/platform → integrations);
  • Knowledge of public cloud (AWS, Azure or GCP) with IaC (Terraform/CloudFormation) and CI/CD (GitHub Actions/GitLab CI);
  • IoT protocols and platforms: MQTT, CoAP, LwM2M; AWS IoT Core/Azure IoT Hub (or equivalents), brokers (MQTT/Kafka);
  • IoT connectivity: 4G/5G, NB‑IoT, LTE‑M, private APNs, eSIM/eUICC, VPNs;
  • Security by design: PKI, certificates, mTLS/TLS, key management, hardening and secure OTA; basic knowledge of LGPD;
  • Observability and SRE: metrics, logs and traces; Prometheus/Grafana/CloudWatch/App Insights; SLO/SLI definition;
  • Distributed systems architecture: microservices, event-driven, pub/sub, resilience (retry/backoff, idempotency, circuit breaker);
  • Integrations: REST/GraphQL APIs, authentication/authorization (OAuth2/JWT), webhooks and messaging;
  • Languages: one primary back-end language (Java/Go/Node.js/Python) and fundamentals in C/C++ for firmware; scripting (Python/Bash);
  • Databases: time-series (InfluxDB/Timescale), NoSQL (DynamoDB/Cosmos/Firestore) and relational (PostgreSQL/MySQL);
  • Practice with code reviews, defining technical standards and leading engineering rituals;
  • Tools: Git, Jira/Confluence, Postman, Wireshark, device simulators, OpenAPI/Swagger.
