Note: The job is a remote job and is open to candidates in USA. Topstep is hiring a Trading Platform Software Support Engineer to turn recurring trader-impacting issues into permanent fixes. The role owns complex escalations across TopstepX and Topstep Brokerage, including reproducing issues, diagnosing code, shipping production fixes, improving observability, and responding to incidents.
Responsibilities
- Drive engineering-routed escalations from reproduction through resolution, collaborating with other engineers as needed to land the right fix
- Write production code across our C#/.NET back-end services and React front-end to resolve escalations directly when the scope is small enough for an on-the-spot fix
- When an escalation requires work beyond an on-the-spot fix, scope it into a well-defined ticket so the work can be prioritized and picked up by any engineer on the team, including this role
- Build and maintain internal admin tooling and operator surfaces that reduce manual intervention from operations and support teams
- Lead complex investigations across distributed traces, database state reconstruction, race conditions, and integration boundary failures
- Reproduce trader-reported issues in a local development environment; pair with engineers when reproduction crosses service boundaries
- Be a main participant in the Trading Platform on-call rotation
- Respond to active production incidents: assess severity, drive stabilization (rollback, hotfix, or mitigation), and keep stakeholders informed while resolution is in progress
- Pull in the right engineers and operations partners quickly when an incident exceeds your scope or requires specialist knowledge
- Lead post-incident reviews for issues investigated and produce candid, learning-oriented write-ups the broader engineering team can use
- Identify the dashboards, queries, alerts, runbooks, and processes that would make investigations easier for yourself and the support team
- Look for recurring manual work across investigation, data export, and administrative actions, and replace it with automation that reduces ongoing toil for the team
- Improve diagnostic instrumentation in the platform itself, including log quality, structured error context, and trace propagation across services
- Be a primary stakeholder of Admin interface functionality alongside the rest of the Production Engineering team to improve tooling for support and engineering needs
- Partner with SWE on root-cause fixes and post-incident actions; partner with QA on regression coverage for previously-shipped bugs
- Partner with Cloud Ops on infrastructure metrics, alarms, alerts, and related observability, both to inform application-level investigations and to proactively flag services that aren’t performing correctly
- Partner with Product to translate recurring trader pain into well-defined backlog items, with you as the engineering author of the case
- Communicate clearly with non-engineering stakeholders about investigation status, root cause, and resolution
Skills
- 3 to 5 + years of professional software engineering experience in production systems, with demonstrated ownership of features end-to-end (design, ship, support)
- Fluency in C# / .NET for back-end services and working proficiency in React (TypeScript preferred) for front-end work
- Strong debugging instincts in distributed systems; you have owned a production investigation end-to-end and can articulate how you ruled hypotheses in and out
- Foundational SQL knowledge with active, hands-on development. Comfortable reading and writing queries against operational data stores as part of investigations
- Hands-on experience with an observability or logging stack (Datadog, Elasticsearch/Kibana, or equivalent), including reading logs, writing queries, and building dashboards
- Proficiency reading and triaging API logs and HTTP traffic; comfortable with tools such as Postman for request/response validation
- Excellent written communication. You can turn a messy investigation into a write-up a non-engineer stakeholder can act on
- Bias toward shipping fixes, not just diagnosing them
- Comfortable with remote work and a Slack-heavy async environment
- Familiarity with financial markets, futures trading, or trading platforms
- Familiarity with AWS (EKS, RDS, etc.)
- Prior on-call / incident response experience
- Experience writing internal tools or admin surfaces in a high-stakes operational environment
- Experience using AI tools (LLMs, coding assistants, agents) to accelerate engineering work across investigation, code generation, and documentation
