Staff Backend Software Engineer
Confirmed on the employer's own hiring board on Oct 17, 2026. First seen by Alion on Aug 3, 2026.
Join Lightfield, an innovative company that builds a living model of a company's customers. As a Staff Backend Software Engineer, you will own core product capabilities end to end, design shared abstractions, and evolve a schema-flexible data model. You will partner directly with product engineers, product leadership, and customers to turn ambiguous needs into practical backend architecture. This role offers meaningful early equity, health insurance, 3 weeks of PTO, and other perks.
Missions
- Posséder des capacités clés du produit de bout en bout, de la définition des exigences client à la mise en production.
- Concevoir des abstractions partagées utilisées par l'interface utilisateur de Lightfield, l'API publique, les agents, les automatisations et les équipes d'ingénierie internes.
- Évoluer un modèle de données flexible en schéma, en forme de graphe sur Postgres, où les clients définissent des objets, des attributs et des relations à l'exécution.
Profil recherché
- Experience operating systems with real reliability, latency, throughput, and correctness requirements- Comfort debugging across multiple layers of the stack, especially when product behavior and system behavior do not line up neatly
- Strong judgment about data models, APIs, system boundaries, migrations, and incremental rollout
- Product orientation: you care about the customer-visible consequences of backend decisions, not only the elegance of the implementation
- The ability to make practical tradeoffs, communicate clearly, and create alignment without relying on formal authority
- A record of owning significant product-facing systems or ambiguous technical projects from design through production
- 7+ years experience
- Strong software engineering fundamentals and substantial experience building backend systems
- Node.js or similar high-throughput service environments
- Postgres performance tuning, query planning, indexing, transaction design, or multi-tenant data modeling
- APIs, queues, workflow systems, background jobs, and distributed systems
- Observability, incident response, service ownership, and production debugging
- Experience in a high-growth product environment
