Senior Software Engineer, Platform

Role Description

As a Senior Software Engineer in Platform Engineering, you will build internal platforms and AI-enabled tooling that make shipping high-quality software the default. You will:

• Contribute to key parts of the Platform roadmap - from problem discovery to rollout and adoption.
• Build developer productivity tools/frameworks that scale quality across teams (not gatekeeping).
• Design and implement CI quality gates (unit/integration/API/contract/E2E), test reliability improvements, and quality signals that prevent production issues.
• Build platforms for automation utilities, reporting, and observability to improve confidence and reduce engineering toil.
• Embed AI-assisted workflows into processes (e.g., test generation, test data generation, failure analysis, flake detection, regression recommendations, smarter triage).
• Partner closely with Product Engineering, SRE/Platform, and Security teams to improve release confidence, reduce regressions, and shorten feedback loops.
• Set standards and build reusable libraries/SDKs so teams can easily "do the right thing" with minimal friction.
• Automate everything that an engineer should not be working on.

Qualifications

• 5+ years of industry experience as a software engineer, preferably in SaaS / product engineering.
• Proven ability to take ownership, drive initiatives, and deliver platforms adopted by multiple teams.
• Strong software engineering fundamentals: system design, APIs, code quality, scalability, and reliability.
• Deep proficiency in at least one high-level language (e.g., Java, JavaScript/TypeScript, Go, Python).
• Strong understanding of modern engineering practices: CI/CD, developer workflows, branching/release strategies, PR checks, build pipelines.
• Experience with cloud infrastructure (AWS / GCP) and distributed systems concepts.
• Strong problem-solving skills, comfort working with complex systems, and a bias toward automation.
• Hands-on experience with AI (must-have):
• Using LLMs/AI agents in engineering workflows.
• Building AI-powered tooling (prompting, evaluation, guardrails, automation integration).
• Practical experience integrating AI into developer productivity platforms.
• Highly data-driven mindset - comfortable defining success metrics, measuring adoption, and iterating.

Requirements

• Experience building/maintaining test automation frameworks (API/contract/E2E), test infra, or quality tooling used org-wide.
• Exposure to microservices architecture, GraphQL/REST, event-driven systems, and contract testing.
• Experience improving test reliability (flake reduction), failure triage automation, test impact analysis, or regression risk scoring.
• Familiarity with observability tools (logs/metrics/traces) and building actionable quality dashboards.
• Experience building internal platforms/SDKs and driving adoption through documentation, enablement, and DX improvements.

Benefits

• Flexible vacation.
• Flexible work times.
• Work from anywhere.
• Equipment you need to do your job.
• Health insurance.
• Attractive ESOPs.

Selection Process

• Initial screening round.
• Technical interview with our engineering team.
• In-depth technical interview with our CTO.
• Meet the founders and discuss our mission and vision.
