Job description

JOB OVERVIEW:

We are looking for a Staff Software Engineer to be the technical anchor for our Engineering team at SalesIntel a deeply hands‑on individual contributor who sets the architecture everyone else builds against. This is a pure IC role: your impact comes from the systems you design and the code you write, not from managing people.

WHAT YOU WILL DO:

• Own the architecture for the team service boundaries, API contracts, data models, and the standards that keep a growing codebase coherent at scale.
• Design and operate high‑scale search indexing, relevance, and predictable low latency as volume and traffic grow.
• Design our APIs and the controls around them: clean contracts, versioning, rate limiting, throttling, and quotas.
• Drive the database layer schema design, query performance, indexing, partitioning, and capacity planning for heavy workloads.
• Lead our most complex, cross‑cutting initiatives, staying deeply hands‑on: writing and reviewing production code and prototyping the hard parts yourself.
• Pay down systemic technical debt and reliability risks before they become incidents.
• Mentor engineers through design reviews and pairing, raising the bar on testing, operability, and system design.

REQUIRED SKILLS & QUALIFICATIONS:

• 7+ years of software engineering experience owning large, ambiguous systems from design through production. Depth and impact matter more than years.
• Strong, proven architecture capability you define the boundaries, data models, and standards others build on.
• Deep expertise in backend development with Java and Spring Boot.
• Experience designing and operating high‑scale search indexing, relevance, and low‑latency query performance under load.
• Extensive API design experience, including the operational controls that keep APIs healthy: rate limiting, throttling, quotas, and abuse prevention.
• Deep database expertise schema design, query optimization, indexing, partitioning, and capacity planning for high‑volume workloads.
• Strong distributed systems fundamentals, with a bias toward staying close to the code.
• Hands‑on experience building and operating services on AWS.
• A plus: experience building agentic systems LLM‑driven workflows, tool/function calling, orchestration, or MCP‑style integrations.
• Excellent verbal and written communication skills
• Strong system design, architectural thinking, and technical leadership
• Ability to engage and influence both technical and cross‑functional stakeholders
• High level of ownership, accountability, and engineering maturity
• Strong organizational skills and ability to manage complexity across multiple initiatives
• Ability to work independently in a remote/global environment
• Passion for mentoring engineers and raising the bar across the team

Success Metrics

In your first 6-12 months you'll have taken ownership of the core layer search performance, API scale, and the data layer delivered a materially more scalable and reliable system across it, and established the architectural standards the team builds against.
