Lead Software Engineer - NBA

Humana

5d•$129,300 - $177,800•Hybrid

About The Position

The Lead Full Stack Engineer owns the NBA platform’s orchestration and state machine, which carries a decision from creation through activation, delivery, and acknowledgment across member engagement channels. Built with Node.js and TypeScript on Temporal, the platform manages durable workflow execution, long-running member journeys, and reliable action delivery using Transactional Outbox and Kafka-based event patterns. The role is accountable for the critical path between decision generation, activation, delivery, and receipt processing, and for the durability, correctness, observability, and timeliness of action delivery at enterprise scale. This is a hands-on technical leadership position. The engineer writes code, leads a small team of engineers and contractors, owns end-to-end delivery for the orchestration pod, and makes its day-to-day architecture decisions. The role also coordinates interfaces and dependencies with decisioning, the Action Library, activation systems, and the platform team. The position is remote or hybrid, preferably based in Boston, Massachusetts. Occasional travel to Humana offices for training or meetings may be required. Typical hours are Monday through Friday, eight hours per day, with some flexibility depending on business needs. Remote or hybrid employees must provide internet service with at least 25 Mbps download and 10 Mbps upload speeds and work from a dedicated space that protects member PHI and HIPAA information.

Requirements

Bachelor’s degree in computer science or a relevant area.
At least 6 years of full-stack software engineering experience, including at least 1–2 years in a tech-lead or senior-lead capacity.
Strong Node.js and TypeScript backend experience building production services.
Hands-on experience with workflow orchestration platforms; Temporal is strongly preferred, or comparable technologies such as Cadence, Step Functions, or Airflow for durable workflows.
Strong distributed systems fundamentals, including event-driven architectures, asynchronous processing, retries, idempotency, and failure recovery.
Experience designing and implementing Kafka producer and consumer patterns in production environments.
Experience building reliable event delivery systems using Transactional Outbox, event-driven integration patterns, or comparable messaging architectures.
Demonstrated ability to lead a small pod through delivery and be accountable for technical outcomes.
Experience operating cloud-native systems on Azure or equivalent cloud infrastructure using Kubernetes, containers, and CI/CD pipelines.
Clear communication skills and ability to represent architecture, delivery status, operational risks, and tradeoffs to technical and business stakeholders.
For remote or hybrid home-office work, self-provided internet service must provide at least 25 Mbps download and 10 Mbps upload, and the employee must work from a dedicated space that protects member PHI and HIPAA information.

Nice To Haves

Production experience with Temporal at scale, including workflow versioning, long-running workflow management, and operational lifecycle management.
Deep experience implementing Transactional Outbox patterns, delivery acknowledgment workflows, dead-letter queue management, receipt reconciliation, and exactly-once processing semantics.
Experience integrating Adobe Experience Platform or comparable activation and engagement platforms.
Experience with Kafka ecosystem tooling, event schema governance, and large-scale event-driven architectures.
Familiarity with the wider NBA platform stack, including React/TypeScript, Java services, and Decision Intelligence systems.
Experience with Helm, Terraform, and Kubernetes-based deployment patterns.
Background in healthcare, insurance, or another regulated industry involving PHI handling, auditability, and compliance requirements.

Responsibilities

Own end-to-end orchestration-pod delivery, including planning, execution, quality, and shipping on time.
Design and build durable, long-running Temporal workflows in Node.js and TypeScript to model member action lifecycles, state transitions, scheduling, activation, and delivery outcomes.
Own the end-to-end action delivery pipeline from decision publication through activation, delivery acknowledgment, and state reconciliation.
Design and implement Transactional Outbox patterns, atomic persist-and-publish workflows, idempotency controls, retry and backoff mechanisms, dead-letter queue handling, and delivery receipt processing.
Own components that activate decisions to Adobe Experience Platform and publish through Kafka output patterns to downstream channels.
Define delivery contracts, activation guarantees, and receipt ingestion patterns for reliable action execution.
Contribute code, including Temporal workflows and activities, Node.js services, Kafka producers and consumers, outbox processors, and integration services.
Make the pod’s day-to-day architecture decisions, including workflow design, state machine modeling, retry and compensation strategies, idempotency, topic strategy, schema evolution, delivery guarantees, and API contracts.
Engineer distributed systems for correctness using idempotent consumers, deduplication, durable state management, safe retries, and graceful failure handling.
Establish monitoring, tracing, alerting, and operational visibility across workflow execution, event publication, activation processing, and delivery acknowledgment pipelines.
Manage and mentor engineers and contractors, run code reviews, uphold engineering standards, and keep the team unblocked.
Coordinate interfaces with decisioning, the Action Library, activation systems, and the platform team; surface dependencies, integration risks, and operational concerns early.
