About the Job

Requirements

Four or more years in release management, release coordination, or a closely related role.
Hands-on experience releasing software for connected devices, consumer electronics, wearables, or Internet of Things products, including firmware updates in the field.
Working knowledge of branching and release strategies, continuous integration and continuous delivery pipelines, and quality assurance cycles; the role partners with engineers on pipelines rather than building them.
Experience with app store review cycles and staged rollouts.
Strong Jira skills, including versions, release workflows, and automation rules.
Ability to communicate clearly when a release is at risk and confidence to call a no-go.

Responsibilities

Own the release calendar and versioning for firmware over-the-air updates, mobile app releases, and backend deployments.
Run release readiness reviews and go/no-go calls, and coordinate release-night execution with engineering, quality assurance, support, and offshore teams.
Manage staged firmware over-the-air rollouts by defining cohorts and stages, monitoring device health, and pausing or rolling back when needed.
Own code freezes, including holiday freezes, and the exception process.
Own pre-release builds and distribution for user acceptance testing, internal testing, influencers, and media.
Own release configuration in Jira, including fix versions, release workflows, and automated release notes.
Plan release and incident coverage for holidays and high-risk launches, with clear escalation paths.
Write and maintain release runbooks so anyone on the team can follow the process.
Track release quality after every release and share findings with the senior technical program manager and engineering leads.

Desired Qualifications

Experience with wearables and vertical integration.
Experience coordinating releases with offshore teams across time zones.

Release Manager

COSMO · Toronto, Canada · Full-time · Posted 2026-11-06

Salary: CAD 95,000–115,000

Workplace: on_site

Description

Location: Greater Toronto Area preferred (remote with periodic on-sites)

The role

You'll own how Cosmo ships. Every release has to land across firmware, software, and cloud services, and you'll be the person who makes that happen on time and correctly. You'll run the release calendar, readiness reviews and go/no-go calls, manage staged firmware rollouts to devices in the field, and keep our release tooling working. You'll partner closely with our Senior TPM, who owns program health and the overall operating rhythm.

What you'll do

Own the release calendar and versioning for firmware OTA updates, mobile app releases and backend deployments.
Run release readiness reviews and go/no-go calls, and coordinate release-night execution with engineering, QA, support and our offshore teams.
Manage staged FOTA rollouts: define cohorts and stages, monitor device health, and pause or roll back when needed.
Own code freezes, including holiday freezes, and the exception process.
Own pre-release builds and distribution for UAT, internal testing, influencers and media.
Own the release configuration in Jira: fix versions, release workflows and automated release notes.
Plan release and incident coverage for holidays and high-risk launches, with clear escalation paths.
Write and maintain release runbooks so anyone on the team can follow the process.
Track release quality after every release and share what you learn with the Sr TPM and engineering leads.

What success looks like

In 30 days, you've run a release alongside the interim owner and documented every manual step.
By 90 days, you own the release calendar and FOTA rollouts, and release runbooks are written for firmware, app and backend.
By six months, releases ship on a predictable cadence, release notes are fully automated and rollbacks are rare and fast.

Requirements

What you bring

4+ years in release management, release coordination or a closely related role.
Hands-on experience releasing software for connected devices, consumer electronics, wearables or IoT, including firmware updates in the field.
Working knowledge of branching and release strategies, CI/CD pipelines and QA cycles. You partner with engineers on pipelines rather than building them.
Experience with app store review cycles and staged rollouts.
Strong Jira skills, including versions, release workflows and automation rules.
Calm, clear communication when a release is at risk, and the confidence to call a no-go.

Nice to have

Experience with wearables and vertical integration
Experience coordinating releases with offshore teams across time zones.

Remote working environment
An opportunity to make a significant impact in a fast-growing company
