Keeping software engineers in flow and unblocked is one of the key responsibilities of software development leaders. In each episode of the Engineering Unblocked podcast, Rebecca Murphey interviews leaders who have navigated challenges of scale, complexity, and growth. You’ll hear from people with lived experience across the software development ecosystem, from CTOs and VPEs to directors and line managers to product managers, program managers, tech leads, and more.
Writing the same book three times with Rebecca Murphey and Otto Hilska
In this special episode, former Engineering Unblocked host Rebecca Murphey returns — now at Honeycomb — alongside Swarmia CEO Otto Hilska, to talk through the third edition of Build: Elements of an Effective Software Organization: what changed between editions, what didn't, and where the industry is headed.
Rebecca looked at a few thousand pull requests at Honeycomb and found that somewhere in the order of 90% were unaffected by human review. Her team now has a goal of merging a quarter of all pull requests without a human reviewer by the end of the year. Otto describes the same bottleneck from the other side: what he calls the AI paradox, where individual developers 10x and the organization gets 10%.
They also get into where the constraint goes next. Otto thinks quality is the under-discussed topic of this era, and that cost and ROI math needs to become standard in every engineering organization. Rebecca thinks the question has stopped being about effective software organizations and started being about effective businesses.

AI's unglamorous wins for developer productivity with Tara Hernandez from MongoDB
In this episode, Tara Hernandez shares what 18 months of rigorous AI experimentation taught her at MongoDB — including why the initial results showed negative ROI, and where her team eventually found the real productivity wins.
Tara explains how AI saved developers an hour a week on coding but had zero impact on product velocity, why the unglamorous outer loop improvements (Slack bots, log analysis, ticket generation) deliver bigger impact than code generation, and how developer productivity ultimately comes down to information flow between humans.
She also gets into why developer experience matters more now than during the hiring frenzy, and why curiosity is what defines good developers.
(0:00) Introduction
(1:04) How Tara became MongoDB’s first VP of Developer Productivity
(6:42) Teaching Pixar how to do software development in 2002
(11:06) Tara's three pillars of developer productivity: tools, communication, and process
(18:52) How the internet changed infrastructure from “not real engineering” to essential
(22:00) MongoDB’s 18-month AI journey: from skepticism to scientific measurement
(25:11) The surprising truth: AI saved coding time but had zero impact on velocity
(27:03) Where AI actually wins: senior engineers with agentic programming
(30:04) What developer productivity teams should focus on in the AI era
(34:14) Why the outer loop matters more than the inner loop
(37:08) Measuring the cost of human-to-human communication
(40:14) Developer productivity is really about information flow
(41:13) Why developer experience matters more now, not less
(44:33) The ethical problem with celebrating AI-driven layoffs

What a year of hands-on AI coding teaches you about good software with Lada Kesseler
In this episode, Lada Kesseler shares what she’s learned from a year of hands-on experience building with AI coding tools — including the three fundamental challenges that define how these tools work, and why understanding limitations is what makes you better at using them.
Lada explains why “focus” is the critical concept most developers miss, how a dedicated committer agent will catch issues that a general-purpose copilot never does, and why software craftsmanship matters more now than ever. She also gets into why using AI to critique itself produces dramatically better results, and how AI works as an amplifier that speeds up both good and bad engineering practices.
