Ivan De Marino, Lead Software Engineer at New Relic, has a unique career path that involves working twice at the company. He joined in 2014 and worked until 2018 to build Synthetics, a new offering for New Relic, before returning as Lead Software Engineer for the Kafka platform team in March this year. Ivan attributes his return to New Relic due to missing their products, especially NRDB, and feeling a sense of mission and purpose that aligns with his values. He praises the company culture, particularly accountability, which emphasizes taking responsibility for mistakes and learning from them. Ivan shares three tips for someone interested in joining the engineering team: establishing a solid relationship with code and software, assuming people have the best intentions in communication, and never beating oneself up over mistakes. New Relic offers opportunities for growth and career development, including support for AWS certifications and paying for exam fees.
