Senior Software Engineer

Role Overview

Senior Software Engineer (Backend) at Bastion, focused on building and improving services in a fast-moving startup environment.

What You’ll Do

First 30 Days

• Learn the service “rails” (architecture, CI/CD, observability, engineering conventions)
• Ship a small feature slice or quality-of-life improvement
• Add tests, dashboards, or runbook notes for areas you touch

By 90 Days

• Own a service surface and raise the bar for reliability and quality
• Lead a medium-scope project (e.g., API contract updates, partner integration, or hardening a critical path)
• Improve logging, tracing, alerts, and failure handling

By 180 Days

• Drive cross-service impact (e.g., API versioning plan, data model migration, compliance-driven workflow changes)
• Shape technical direction via design docs and mentoring
• Collaborate with product and compliance on pragmatic, regulation-aware tradeoffs

Example Problems You May Work On

• Designing stable, evolvable custody/transfer/issuance APIs without breaking downstream clients
• Building idempotent, high-throughput job flows with strong audit trails
• Hardening key operations with hardware-backed isolation and robust key policies
• Improving p95 latency via query tuning, caching, or backpressure

Requirements & Qualifications

• Strong backend engineering background (Go and/or TypeScript/Node.js)
• Experience shipping production features with quality practices (tests, observability, operational readiness)
• Ability to lead projects and improve reliability/metrics over time

Nice-to-Haves / Likely Stack Exposure

• gRPC and REST; GraphQL/tRPC at the edge for BFFs
• Postgres, Redis, and Kafka; async workflow systems
• Temporal workflow management
• AWS, Kubernetes, Terraform
• Datadog, Grafana, Sentry, and incident/ops tooling
