Job description

Logixboard builds software for the freight forwarding industry. Our platform spans two areas: a white-labeled supply chain visibility product that freight forwarders offer to their customers, and AI-powered tools that automate the repetitive data entry and document handling work that freight operators do every day. Together, these products serve both sides of the logistics relationship; the customer tracking their cargo and the operator managing it.

We are a remote-first, product-driven company. We value high ownership, thoughtful technical decision-making, and building software that genuinely makes freight professionals' work better.

Role Summary

We\'re looking for a Senior Software Engineer to work across all parts of our platform. This is a full-stack individual contributor role. You\'ll build features end to end, from the React frontend through the Node.js backend, down to PostgreSQL schema design and AWS infrastructure. You\'ll work on things like real-time shipment visibility, AI-powered data extraction, TMS integration workflows, and the APIs that tie it all together.

You\'ll work closely with Product, Design, and other engineers to understand the problem, decide on the approach, and own the outcome. We look for engineers who are curious about the full context of what they\'re building and why, and who thrive when given the autonomy to figure out the best path forward.

This role reports to the CTO.

What You\'ll Do

Build Across Both Products

• Ship features across the full platform, from customer-facing visibility dashboards to operator-facing AI-assisted workflows.
• Work in our TypeScript monorepos: React frontends (Vite, MUI, tRPC) and Node.js backend services across Express, PostGraphile/GraphQL, and tRPC.
• Design and own database schema changes in PostgreSQL: migrations, query performance, data modeling for complex logistics domains.

Integrations & Workflow Orchestration

• Build and maintain durable integration workflows using Temporal.io that connect with TMS platforms (CargoWise, Descartes, McLeod, and others).
• Work with event-driven patterns across SQS, Kinesis, EventBridge, and Lambda to process shipment data, documents, and notifications at scale.
• Design integrations that are resilient to the realities of third-party systems: inconsistent APIs, XML payloads, FTP-based file exchanges, and unpredictable response times.

Infrastructure & Reliability

• Contribute to our multi-region AWS infrastructure (us-west-2, us-east-2, eu-west-3) using Terraform and Spacelift.
• Improve observability and reliability using Datadog (APM, traces, dashboards), Sentry, and structured logging.
• Participate in incident response and own the reliability of the systems you build.

Team & Culture

• Participate in code reviews, architectural discussions, and design reviews.
• Mentor other engineers, both in the US and in India, and raise the bar on code quality, testing, and operational practices.
• Communicate clearly and asynchronously. We\'re a distributed team and writing matters.
• Participate in on-call rotations. Our customers depend on us around the clock, and we support the platform 24x7.

What We\'re Looking For

• 6+ years of professional software engineering experience, with meaningful time spent building and operating production SaaS applications.
• Strong proficiency in TypeScript and Node.js. This is our primary language across the entire stack: frontend, backend, infrastructure tooling, and integration workers. You should be deeply comfortable here, not just familiar.
• Deep experience with React and modern frontend tooling (Vite, TanStack Query, component libraries, state management). You can build complex, interactive UIs and understand the performance and UX implications of your frontend choices.
• Solid understanding of relational databases, particularly PostgreSQL: schema design, query optimization, indexing strategies, and migrations. We have a large, evolving schema and you\'ll be making meaningful changes to it.
• Experience building and operating services on AWS. We use Lambda, SQS, S3, DynamoDB, RDS, Cognito, CloudFront, Kinesis, EventBridge, and more. You don\'t need to know all of them, but you should have real experience with AWS-based architectures.
• Comfort working in monorepo environments. We use Nx and Yarn workspaces across multiple repos. You should understand dependency management, build caching, and the tradeoffs of shared libraries.
• Strong testing discipline: unit tests (Jest/Vitest), integration tests against real databases, and E2E tests (Cypress). You write tests not because someone told you to, but because you\'ve been burned when tests were missing.
• Clear communication skills. You can articulate technical tradeoffs, write a concise design doc, explain a complex system to a non-technical stakeholder, and give direct, constructive feedback in code reviews.
• High ownership. You care about the outcome, not just the output. When something breaks, you dig in. When requirements are ambiguous, you clarify. When the approach isn\'t working, you speak up.

Preferred Qualifications

• Experience with Temporal.io or similar workflow orchestration engines (Cadence, Step Functions, Airflow). We use Temporal heavily for our TMS integrations and it\'s a core part of the architecture.
• Familiarity with GraphQL: particularly PostGraphile, code generation tooling, or Apollo/URQL clients.
• Experience with tRPC for type-safe API layers.
• Infrastructure-as-code experience with Terraform. We manage all AWS infrastructure through Terraform and Spacelift.
• Background in logistics, supply chain, or freight tech. You understand what a B/L is, why customs entry deadlines matter, and how freight forwarders operate. This is not required, but it dramatically accelerates your impact.
• Experience with AI/ML integration: working with LLMs, document extraction pipelines, or embedding AI capabilities into product features.
• Experience with feature flags (LaunchDarkly), observability platforms (Datadog), or multi-region deployments.
• Location: Remote US (all time zones welcome, though most of the team is on Pacific and Eastern)
• Type: Full-time
• Reports to: CTO

Logixboard is an equal opportunity employer. We welcome candidates of all backgrounds and do not discriminate based on race, color, religion, sex, sexual orientation, gender identity, national origin, disability, veteran status, or any other protected characteristic.

Compensation

The base pay range for this role is $180,000 – $220,000 per year.
