What project we have for you

Our client is one of the leading meal kit companies. They’re  providing more than 120 million meals to > 4 million households worldwide in 14 countries across 3 continents. From procurement tools to conversion rate optimization, live pricing tools, payment services and add-on upselling features, the company works on a wide variety of challenging problems.

Now the project is focused migrating 10,000+ users from Slack Enterprise Select to Enterprise+.

We are looking for an engineer who can independently own the technical risk surface of the migration – making judgment calls on app compatibility, designing testing methodology from scratch, producing runbooks, and bridging the gap between Slack’s guidance and our need for certainty. The engineer will own the Technical Workstream end-to-end.

What you will do

What you’ll do

• Take ownership of the technical risk assessment for Slack apps, workflows, integrations, and custom automations
• Assess app compatibility and make clear technical recommendations on migration readiness
• Design and execute testing methodology for the migration, including smoke tests and downtime scenarios
• Create detailed runbooks that can be followed during the migration under time pressure
• Coordinate with app owners, workflow owners, Slack PS team, and internal stakeholders
• Translate Slack guidance into practical technical actions and identify gaps or risks
• Work independently in an ambiguous environment and make judgment calls where needed
• Ensure the migration is technically safe, well-tested, and causes minimal business disruption

What you need for this

Requirements

Must Have:

• Solid experience  JavaScript, TypeScript, and Python
• Deep understanding of Slack’s platform architecture – APIs (Web API, Events API, RTM), webhooks, workflows, bot tokens, OAuth scopes, Slack apps vs legacy integrations
• Experience with enterprise Slack administration or Slack app development at scale
• Experience in working with AWS
• Ability to read, assess, and make risk judgments on custom app code across multiple languages/frameworks
• Comfortable designing testing methodology without vendor support, including smoke tests for hard downtime and soft downtime
• Operational discipline: can produce runbooks that another engineer could execute under pressure
• Can work independently with ambiguity
• Strong communication skills and sense of ownership — needs to coordinate with 100+ app and workflow owners, explain technical implications to non-technical stakeholders, and work directly with Slack’s PS team
• Makes unilateral calls on: app compatibility classification, test methodology, Sandbox configuration, runbook content, vendor outreach approach.
• Great communication skills, at least Upper-Intermediate level of English

Nice To Have:

• Experience with enterprise platform migrations (any SaaS — not necessarily Slack)
• Familiarity with workflow automation platforms (Slack Workflow Builder, Zapier, custom integrations)
• Experience with SSO/SCIM provisioning in enterprise contexts
• Background in food production/logistics operations (understanding why a workflow failure at a DC is different from a notification bot failing)
