Solutions Engineer (IoT)

About the role

The world still has coverage blind spots. You could help eliminate them at Skylo.

Skylo has pioneered a standards-based approach to satellite connectivity. We connect smartphones and IoT devices directly to satellites. No special hardware, no entirely new networks. Just billions of existing devices, suddenly reachable anywhere on Earth. We're not building toward this future. We're already in it.

Our direct-to-device service is live on millions of activated devices across five continents, covering more than 72 million square kilometers, in partnership with leading satellite operators, mobile network operators, Tier-1 chipset makers, and OEMs worldwide. And we're just getting started.

At the heart of it all is Skylo's commercial NTN vRAN: a 3GPP standards-based, cloud-native platform that seamlessly bridges terrestrial and satellite networks. It's the infrastructure that makes true anywhere, anytime connectivity possible.

When you join Skylo, you'll work at the intersection of three markets reshaping how the world stays connected: mass-market consumer devices, automotive, and industrial IoT. Enabling people outdoors and critical workflows in the world's most remote places.

This is a rare chance to work on technology that matters, at a company that's already proving it works

This role is hybrid 3 days/week in Mountain View, CA

About the Role

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.

Responsibilities

• 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.
• Design and validate end-to-end data flows from device firmware through the core to the customer cloud (e.g. AWS IoT, Azure IoT).
• Own the IP networking path to the customer: APN design, IP addressing, DNS, routing, firewall/NAT behavior, and secure interconnect (IPsec/VPN tunnels, private/dedicated connectivity) - including how data egresses the core over the roaming/IPX path where relevant.
• Build and expose APIs - REST/webhook integrations, NEF/SCEF exposure APIs, and network-exposure interfaces (e.g. CAMARA-style) - so customers can provision, manage, and consume data programmatically.

Customer & partner support

• Serve as the top-tier technical escalation point for module vendors, OEMs, and enterprise customers.
• Reproduce, root-cause, and resolve field issues spanning device, RAN, core, and application layers.
• Developer Enablement: Build and maintain high-quality reference implementations, quick-start guides, sample code, and technical integration patterns.
• Workflow Optimization: Architect the self-service OEM and developer trial journey, systematically eliminating friction from documentation and product workflows.

Required Qualifications

• 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.
• Application-layer + full-stack ability - CoAP/LwM2M/MQTT-SN, NIDD, embedded C, Python, and cloud/API integration.
• 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 Qualifications

• 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.

What We Offer

• Competitive compensation packages including a stock option-based equity program
• Comprehensive benefits including medical, dental, vision, and retirement plan
• Monthly allowances for wellness and education reimbursement
• A generous time-off policy, holidays, and the opportunity to temporarily work abroad
• A once-in-a-career opportunity to operate the world's first commercial, live direct-to-device satellite network
• Access to a world-class team across software, hardware, chipsets, telecom, satellite, and network virtualization
• Open, transparent, inclusive culture that blends Silicon Valley, Nordic, and South Asia characteristics

• The estimated base salary range for this role is: $155,000 - $165,000
• Within the range, individual pay is determined by work location and additional factors, including job-related skills, experience, and relevant training.
• In addition to base salary, Skylo offers a competitive benefits package including health insurance, retirement plans, paid time off, and equity options.
