Job summary

Skylo is seeking a Staff Network Performance Engineer to own KPI definitions and metrics within our OSS platform, bridging raw network counters with dashboards, alarms, and reports that Engineering, NetOps, and leadership rely on to understand how the Skylo network is performing. This role is based in Espoo, Finland, and you will work onsite three days a week as part of a fast‑growing team.

You will implement KPIs for availability, latency, throughput, attach/registration, paging, and

Qualifications

• 8+ years in telecom network performance, OSS/BSS, or network engineering roles with hands‑on KPI/counter implementation.
• Experience implementing and validating KPIs/metrics on an OSS/EMS platform (counter and formula configuration).
• Solid understanding of 3GPP counters and KPIs across RAN and Core; NB‑IoT, NTN, or satellite experience is a plus.

Responsibilities

• Define and implement network performance KPIs and metrics for the OSS platform.
• Build and configure KPI formulas, counters, and dashboards with OSS and NetOps teams.
• Design and run validation tests to confirm KPI accuracy before production rollout.
• Collaborate with Network Implementation, NetOps, and Systems Test teams to align KPI definitions with release needs.
• Maintain single source of truth for KPI definitions and data lineage.

Job description

Position Overview

Skylo is hiring a Staff Network Performance Engineer to own the definition and implementation of network performance KPIs and metrics within our OSS platform, and to validate that those metrics are accurate and trustworthy before they reach production. You’ll be the bridge between raw network, RAN, and Core counters and the dashboards, alarms, and reports that Engineering, NetOps, and leadership rely on to understand how the Skylo network is performing.

This role is based in Espoo, Finland, one of Skylo’s core engineering hubs and fastest‑growing sites. You’ll work onsite three days a week as part of a team that’s scaling quickly.

How You Will Contribute

• Implement network performance KPIs and metrics (availability, latency, throughput, attach/registration success, paging, and satellite‑link‑specific counters) for implementation in the OSS platform.
• Build and configure KPI/metric formulas, counters, and dashboards directly in the OSS platform, working closely with OSS and NetOps engineering.
• Design and run validation test cases in lab and pre‑production environments to confirm KPI accuracy, catch counter drift or double‑counting, and sign off before production rollout.
• Partner with Network Implementation, Network Operations, and Systems Test teams to align KPI definitions with real operational and release‑readiness needs.
• Maintain a single source of truth for KPI/metric definitions, thresholds, and data lineage so metrics stay consistent as the network and OSS platform evolve.
• Identify gaps in existing observability, propose new metrics, and retire or replace metrics that no longer reflect network reality.

What We Look For

• 8+ years in telecom network performance, OSS/BSS, or network engineering roles, with direct hands‑on ownership of KPI/counter/metric implementation.
• Practical experience implementing and validating KPIs/metrics on an OSS/EMS platform (counter and formula configuration, PM/FM data pipelines).
• Solid understanding of 3GPP counters and KPIs across RAN and Core; NB‑IoT, NTN, or satellite network experience is a strong plus.
• Comfortable designing and executing validation test plans in lab and pre‑production environments, with a rigorous approach to sign‑off before production changes.
• Proficiency with SQL and a scripting language (Python preferred) for data validation, and familiarity with dashboarding/reporting tools (e.g., Grafana).
• Track record of working cross‑functionally with NetOps, Network Implementation, and Test teams in a fast‑moving environment.
• Bachelor’s or Master’s degree in Electrical Engineering, Telecommunications, Computer Science, or a related field.

Benefits

• Competitive compensation packages
• Occupational Healthcare and Health and Life Insurance
• E‑passi including wellness, culture, lunch and commuting benefit
• Phone & Internet allowance
• Individual learning & development budget for further personal and professional development
