Job description
Software Engineers in the Engineering team work hand-in-hand with the Product team, from exploration, design, and roadmap prioritization to implementation, and deployment in production. At Joko, we have firsthand experience that teams with engineers who possess a diverse range of skills, and where engineering and product collaborate closely, are able to deliver a truly delightful and innovative user experience.
The Engineering team is currently growing fast to continuously innovate on all parts of our product and tech stack and to empower the revolution of the way people shop online.
What you will do
At Joko, we're entering a new stage of scale: over half a million active daily users, and zero-downtime expectations. As our Staff Platform Engineer, you'll shape and lead our platform efforts. You'll be the first senior engineer focused on these topics, building on work currently spread across the team and turning it into a clear, reliable, high-leverage platform that helps everyone ship faster and safer.
- Infrastructure: Make our production infrastructure more scalable and resilient (runtime reliability, capacity, failure modes), so we can grow fast without compromising stability.
- Monitoring & alerting: Build best-in-class observability (metrics, logs, tracing, SLOs) and an alerting strategy that is actionable, low-noise, and improves incident response and on-call quality.
- Cost & performance: Optimize our architecture to balance reliability, performance, and cloud costs-identify the biggest cost drivers, simplify where it matters, and turn infrastructure efficiency into a measurable business lever.
- Developer experience: Treat our engineering workflows as a product-accelerate CI/CD, releases, environment management and automation, and create golden paths that make the right way the easiest way.
- Security baseline: Raise the security bar across infrastructure (IAM, secrets, hardening, security monitoring) with pragmatic solutions that scale with the team and don't add friction.
- Technical leadership: Define the platform roadmap, align stakeholders, and lead cross-team initiatives end-to-end-bringing structure, standards, and mentorship so platform practices become shared, not heroic., Half-day each week dedicated to leveling up with AI by exploring new tools, iterating hard, and sharpening your skills
- Yearly offsite in amazing locations and budget for team-building events & monthly in-person gatherings
- Contribution to your ClassPass subscription
- 8-week leave paid 100% for the second parent
- ...and much more, check the full list !
Our hiring process
-
Intro call: Quick screening with the Hiring Manager or the Talent team.
-
Step 1 - Team interview (45 min): Conversation with two Joko team members (could include the Hiring Manager, people from the team you'd join, or colleagues from other teams).
-
Step 2 - Role-specific assessments
-
For non-tech roles: Take-home case study followed by a 45 min interview. We assess both your output and how you think in real time. The exercise will be relevant to the role (e.g. analysis, strategy, or process design).
-
For tech roles: Live technical interviews:
-
Coding interview + System design interview
-
For research internships, an additional round may involve analyzing and presenting a research paper
-
Step 3 - Leadership interview (45 min): Conversation with a SteerCo member and a Founder.
-
References: Up to 3 calls with former colleagues or managers.
Requirements
Production reliability & scale: Strong track record operating and evolving production systems (observability, incident response, scalability, reliability patterns) in environments with real traffic and high expectations.
- DevOps & automation mindset: You consistently improve how engineers ship-CI/CD, releases, automation, tooling-and you care about fast feedback loops and day-to-day developer productivity.
- Cost/performance tradeoffs: You're comfortable making pragmatic architectural decisions that balance reliability, latency, and cloud costs, with a clear focus on impact.
- Security fundamentals: You have solid infrastructure security basics (permissions/IAM, secrets, least privilege, hardening). You don't need to be a full-time security specialist, but you know how to raise the baseline.
- Cloud & modern infrastructure: Experience with AWS (we run a server-less setup) or equivalent; familiarity with IaC and modern deployment patterns is a strong plus.
- Strong software engineering foundations: You're a strong engineer first (design quality, testing, maintainability) and you bring that rigor to platform work.
- Product-minded: Strong sensitivity to user experience, performance metrics, and real-world usage at scale.
- Problem solver: Comfortable working in complex, evolving codebases, with the patience and pragmatism to improve them incrementally.
- Collaboration & influence: You communicate clearly, raise the bar through reviews and mentorship, and partner well with engineers and product stakeholders.
- Languages: Fluent in English, both written and spoken. French is not required.
