Skylo Senior IoT Solutions Engineer driving chipset and module enablement for Skylo's satellite connectivity network. Owns device and application enablement, reference designs, and developer support for NB-IoT NTN technology.
Responsibilities
Skylo is building a developer and device ecosystem that makes NTN (Non-Terrestrial Network) connectivity practical to adopt. We are hiring a hands-on Senior IoT Solutions Engineer to drive chipset and module enablement, firmware support, reference designs, and first-run developer journeys into a reliable product capability. You will guide external developers from unboxing to a validated NB-IoT NTN attach and data session without continuous engineering assistance.
Full-stack device & application enablement
Own chipset and module bring-up on the Skylo network: attach, provisioning, firmware validation, AT command behaviour, certification support (GCF/PTCRB where relevant).
Drive reference designs and integration guides for OEMs across IoT, automotive, and enterprise.
Optimise application behaviour for the constraints of NB-NTN: link budget, latency, duty cycle, and power (PSM / eDRX / RAI).
Define the reference architectures, debug tooling, integration guides, and support playbooks the vertical runs on — hands-on, not by delegation.
Set the technical interfaces with Network Engineering, Product, and Carrier Partnerships.
RAN & NTN behaviour
Be the deep expert on NB-NTN radio behavior — link budget, Doppler compensation, timing advance, satellite pass/visibility windows, and store-and-forward vs. real-time modes.
Own TN ↔ NTN switching: PLMN/network selection logic, RRC state behavior, mobility between terrestrial and non-terrestrial coverage, and the device-side configuration that makes switching reliable in the field.
Application layer, cloud & connectivity
Guide customers on NIDD (Non-IP Data Delivery) via NEF/SCEF over T6a, and on CoAP, LwM2M, MQTT/MQTT-SN, and payload optimisation for constrained links.
Qualification
Solid cellular IoT knowledgeHands-on with chipsets and modules — eIP networking — solid grasp of APNNB-IoT NTNPractical familiarity with Wireshark
Required
5+ years of experience in IoT solutions engineering, embedded systems, field applications engineering, or a highly technical customer-facing engineering role.
Strong hands-on C/C++ embedded development skills, RTOS experience, module bring-up, and cellular AT-command interfaces.
Solid cellular IoT knowledge, including network registration, attach sequences, SIM/eSIM profiles, PLMN selection, and packet data.
Strong command of NB-IoT and NB-NTN — 3GPP Rel-17 NTN concepts, RRC, NAS, PSM/eDRX, RAI, and the radio realities of a satellite link.
Hands-on with chipsets and modules — e.g. Qualcomm 9205S/212S, Sony Altair, Sequans, MediaTek at the silicon level; Quectel, u-blox, Murata, Fibocom, Telit at the module level.
Practical RAN understanding — link budgets, RF debug, coverage and interference reasoning, not just theory.
Modem log and packet-level debug — QXDM/QCAT or equivalent, AT command mastery, PCAP analysis.
Fluency in TN↔NTN switching / network selection behavior on real devices.
Cloud — hands-on with at least one major IoT cloud stack (AWS IoT / Azure IoT), device-to-cloud data pipelines, and identity/security for connected devices.
IP networking — solid grasp of APN, IP addressing, DNS, routing, NAT/firewall, and secure interconnect (IPsec/VPN, private connectivity); GTP / GRX/IPX awareness a plus.
APIs — designing and consuming REST APIs and webhooks; familiarity with network-exposure APIs (NEF/SCEF, CAMARA) is strongly desirable
Preferred
NB-IoT NTN, satellite IoT, 3GPP standards, or roaming experience.
Practical familiarity with Wireshark, signaling analytics, BigQuery, or developer portals.
A proven track record of creating developer documentation that materially reduces incoming support tickets.
