No endless meetings here if it can be done today were all about getting it done today.

What is this role like

Were hiring a Software Engineer for our Infrastructure team the backbone of everything Topsort runs on. This is not a supporting role. Infrastructure at Topsort is a first-class mission-critical function. When our infrastructure is healthy every retailer and marketplace our customers serve gets fast reliable and fair auction results. When its not we feel it everywhere.

Youll be building and owning the systems that power our real-time auction engine API platform and internal developer tooling at a scale and reliability standard that leaves no room for sloppiness. We need someone who treats production like it matters because it does.

What Youll Do

Own the platform -Design build and maintain the foundational infrastructure that every Topsort product and engineering team depends on from compute and networking to deployment and observability.
Raise reliability - Define and enforce SLOs build alerting systems that catch issues before customers do and lead postmortems that actually prevent recurrence.
Make deployments boring - Build CI/CD pipelines and deployment systems that are so reliable theyre invisible. Automate the toil out of every release.
Manage infrastructure as code - Own our cloud infrastructure (AWS/GCP) through Terraform or equivalent no snowflake servers no manual configuration drift.
Enable developers - Build internal tooling and platform capabilities that make every Topsort engineer faster safer and more autonomous. Your customers are your colleagues.
Harden security - Implement and enforce security best practices at the infrastructure level secrets management network policies RBAC supply chain integrity.
Scale proactively - Capacity plan load test and tune our systems ahead of demand not in reaction to a page at 2am.
Participate in on-call - We take production seriously. Youll join the on-call rotation and be expected to respond resolve and document.

What We Think You Need to Be Successful

Were open to candidates who dont check every box but show strong potential.

Bachelors in Computer Science engineering or a related field from top schools
25 years of software engineering experience with a meaningful portion focused on infrastructure platform or SRE work
Solid hands-on experience with Kubernetes in production not a homelab not a tutorial but real clusters under real load
Experience with at least one major cloud provider (AWS preferred) and infrastructure-as-code (Terraform or similar)
Strong fundamentals in distributed systems you understand CAP theorem eventual consistency and failure modes before they happen
Experience building or maintaining CI/CD pipelines (GitHub Actions ArgoCD or similar)
Comfort with observability tooling metrics logs traces and the discipline to use them proactively
A security-conscious mindset: you think about blast radius principle of least privilege and secrets rotation without being asked

Youll stand out if you have:

Experience in high-throughput low-latency systems (ad tech fintech real-time bidding or similar)
Familiarity with service mesh eBPF or advanced Kubernetes networking
Experience with database infrastructure and data streaming
A track record of improving developer experience and reducing time-to-deploy
Experience at a high-growth startup where infra had to scale faster than the team

Who Thrives Here

Topsort engineering is not for everyone and thats intentional. Youll do well here if:

You take ownership seriously . You dont wait to be assigned a problem. If you see something broken you fix it or escalate immediately.
You write production-grade code not proof-of-concepts. You document your work write runbooks and leave systems better than you found them.
Youre honest about tradeoffs. Wed rather hear this will take two weeks to do right than ship something fragile under the guise of speed.
You sweat the details especially in infra. A misconfigured RBAC rule a missing circuit breaker an oversized pod resource request these things matter here.
You communicate clearly and often. We build in the open. Cross-functional collaboration is expected not optional.
Youre intellectually curious and you stay current. The infrastructure landscape moves fast. We expect engineers on this team to help us adopt the right new tools and resist the wrong ones.

We are proud to be an equal opportunity employer and to foster a workplace where diversity is valued and celebrated. We believe that diverse perspectives and experiences strengthen our teams and drive better outcomes. We respect and value any race religion color national origin ancestry caste gender gender identity or expression sexual orientation age disability medical condition pregnancy genetic information marital status or military service.
