Note: The job is a remote job and is open to candidates in USA. Loadsmart is a growth-stage technology company valued at over $1 billion, focused on reinventing the future of freight. They are seeking a Senior Python Back End Engineer to lead technical initiatives and evolve core systems that power freight brokerage operations.
Responsibilities
- Own and evolve core systems for freight brokerage operations and related services: quoting, booking, pricing and rate logic, contracts, carrier compliance, facility matching and location/address data quality, and scheduling-oriented workflows
- Lead technical initiatives across several Python/Django services, including design, phased rollout, and safe deprecation—not only single-service features
- Drive platform and reliability work: database and dependency upgrades, search/indexing changes, performance tuning (queries, indexing, caching), secrets/credential patterns, and tooling that prevents bad deployments (e.g. migration safety, validation pipelines)
- Ship high-impact product and revenue work: pricing and benchmark integrations, compliance/load-registration flows, feature-flag and segmentation strategies, and scope-shaping that ties technical design to business outcomes
- Define engineering standards for the squad and beyond: ADRs, shared client/integration layers, test and observability patterns, and code review culture that teaches (SOLID, architecture, thorough PRs)—including shared patterns between API and UI
- Operate production systems: incident response, war-room coordination, root-cause analysis, and fast stabilization PRs when freight brokerage operations are at risk
- Collaborate tightly with product on discovery and requirements—framing problems, narrowing scope with technical options, and sometimes presenting outcomes to senior stakeholders
- Mentor and level up teammates through pairing, design review, and informal leadership—without necessarily being a people manager
Skills
- Senior back-end engineer with a track record of owning ambiguous, multi-step projects end-to-end across API and UI (design → implementation → rollout → observability), comparable to tech-lead-level delivery on a business-critical system
- Strong Python and Django (or demonstrably deep transfer: e.g. long professional experience in Java/JVM ecosystems plus substantial Python web work in production)
- PostgreSQL expertise: schema design, production database migrations, query plans, indexing, and fixing latency/regression issues—not only CRUD
- Distributed systems and multi-service reality: async jobs/queues, events, idempotency, integration failures, and debugging across service boundaries
- Proven impact outside 'greenfield' only: experience in large or evolving codebases, modernization (framework/DB/search/runtime upgrades), or cost/performance work with measurable outcomes
- Production mindset: on-call or equivalent experience, incident response, and prioritizing stability under operational load
- Technical leadership without relying on title: examples of leading migrations, integrations, or architecture decisions; mentoring; and aligning engineers across teams
- Clear written and verbal communication: design docs, ADRs, RFCs, or review threads that other engineers adopt as reference
Benefits
- Competitive base salaries - we believe in rewarding top talent
- Extremely competitive Equity package - become a shareholder in our company!
- Loadie Time Off - PTO and sick days without a limit
